Awesome gun smith/tool shop; but cant touch anything 😢 Still, all the stars!

Yall do awesome work definitely coming back for more

Sinner Mass mounted a scope for me and I couldnt be happier. I was told it would take a day or two, but got a call an hour later that it was ready. Quick service at a very reasonable price, not sure what more I could have asked for.

Sinner Mass does it again!! Time after time I am more impressed with the work that comes out of the guys at SM. I never had custom gun work done besides a trigger or small things until last year when I met Luke and Kevin at a Veteran Charity event and saw their work first hand. I have now done almost a dozen different custom orders through them and I am impressed more every time. I can give Luke or Ryan an idea and general direction and let them run with it creatively and couldn’t be happier! With Sinner Mass you are in great hands and the work & customer service is too notch! Thanks for everything guys!!

Love supporting fellow veterans when ever I can. The guys here are great and do top notch work. I take all of my NFA items here for engraving. I also have had some trigger jobs done here. Very pleased with their services and will continue to bring them my business.

Are you kidding me?! This place is amazing. They can do nearly anything to a Glock. I had them mill my G26.5 for an RMR and Cerakote the slide ODG. I had my slide back in less than a month and I am very satisfied with their prices and quality of work. This is who John Wick should have gone with for guns and mods.

The guys here do great work and i appreciate them could not be happier with the results will definitely bring in future work

Pros: Decent quality cerakote (not great). Relatively cheap (who charges tax on shipping??).Cons: Open-ended timelines (which they consider normal, when its not to anyone else in the industry) and poor communication.Basically, you get what you pay for. Not the best quality. Got my gun back with a few spots painted unevenly - dry sprayed, with dull finish right next to shiny. Not a big deal for me, since its an antique and has rough spots anyway, but would be more of an problem with a new gun. Whats more of an issue is that there is no way of knowing when your project is going to be completed. My project took 7 weeks, and it wasnt exactly a huge challenge - a small handgun, single color frame and slide, second color all small parts. Original estimate was 3 weeks. They prioritize other things, over-promising and misinforming along the way, resulting in a way longer timeline. You may get a better service if you are a local customer, not sure. Absolutely not worth the aggravation for mail-order - plenty of other, reputable cerakote applicators around.

Outstanding work! It’s nice to have a reliable Cerakote applicator right down the road. A great team, full of 2a knowledge. Had my Glock slide milled, cerakoted, and laser engraved. Will be bringing back a lot more work!

Sinner mass is definitely a great place and great people to work with. Dropped off my G22 and got back a masterpiece, I can’t believe how great it came out they definitely deserve all the praise they get. Wholesome people that I would definitely drop off my pistol to again

Luke and his crew at Sinner Mass really raise the bar for custom gun work. Every project they do is carefully tailored to the individual customer’s vision. I have several custom guns from SMF and am extremely pleased with all of them. However, I am kinda sad that David left. I wish him the best of luck as he works to fulfill his dreams as portable restroom attendant.

Great guys to work with. Theyre very knowledgeable, extremely helpful, have very fair prices, and superb workmanship. Not to mention the quick turnaround time. Would and will use again and again, would also highly recommend. Thanks again SMF Crew, yall ROCK!!!

Great Group of Men, that do Fantastic work. I Bought a new Compensator for my AR-10 Needed it Cerakoted, Contacted them when Part came in, and got it back today. Fantastic Job, the finished product is superlative to any other I have seen. Thank You David, Luke & Mark.. An Ol Army Vet..

Had the guy there custom build an AR pistol in .300 Blackout and cerakote it in Black Cherry. When it was done, I thought it was the more beautiful firearm I had ever seen. It was packed with all the components I had hoped for. David built it for me and had free range on what parts to use. He is a Master and Artist. Yall have me as customer for life. Shout out to Kevin as well. I recommend these guy 100%

Got two rifles there. Good guys. Veteran owned.

Regarding Sinner Mass, Luke and Kevin did an awesome job on an S&W, M&P custom slide job that I recently hired them to produce.The result of the project was beyond expectations with stellar performance and I will definitely be sending business their way in the future. I highly recommend Sinner Mass.

Im not one to write reviews, but these guys definitely deserve to be patted on the back.This year has been an absolute nightmare for the gun industry. Its been just about impossible to find parts, ammo, and good service. These guys provided all 3. They were upfront that it would take much longer than normal due to limited resources and overwhelming demand, but the project came out better than I could have imagined, well within my budget.I had them Cerakote my AR-10 with a FDE multicam pattern, and they also stippled and did some frame mods on my Glock 19.These guys HUSTLE! You can tell they love what they do, and it seems there is not enough hours in the day to keep up with the demand they have for their services. Throw on top, that everyone that works there is a disabled combat Veteran, Im surprised anything gets done (the VA is a joke), but they do, and then some!I will be brining back many more projects for many years to come. Very thankful for these gentlemen as they continue to serve the public the best way they know how. Im thankful that I do not need to ship out my guns anymore.

Almost impossible to reach anyone at the Shop. They were recommended to me by an aquiantance but I was never able to have them even look at my project. I gave up after a month or so, and went elsewhere for my Cerakote project.

Sinner Mass was a pleasant surprise. I am a first time gun buyer, and I feel like Im already an expert after the buying experience with the guys over at Sinner Mass. Very informative and patient. They have a lot of cool stuff there too that I look forward to doing to my gun. Highly recommend!

This was my first time here, and overall it was a positive experience. My husband has been wanting to Cerakote his AR15 for quite some time, so with the holiday season quickly approaching, I figured I would give these guys a shot.Wasnt the easiest place to find, as their address is on Broadway, but to get to the shop you have to enter from the 410 access road due to Caliber Collision. I was greeted by a very friendly dog, Gunner (very appropriate), and two very polite gentlemen.They knew exactly what I was wanting to accomplish and even made some suggestions to make it a more impressive gift without adding much cost at all. The also laser engraved of our kids initials on there. The gun came out beautiful and my husband has thanked me 100 times over for it.I would have loved to give this business 5 stars, but I do see some room for improvement. While their retail space was very cool, and unique, I found it a tad underwhelming with the guns they have available to put your hands on. This is not your standard gun shop, but from what it sounds like, they arent trying to be standard. They said there will be more guns up on the wall by the next time I return, but they will all be customized. No stock guns.Anyway, give these guys a shot, theres no doubt in my mind youll be impressed with the quality of work and customer service.

The older i get, the less i trust people. Luke and his team have restored my faith in humanity. Its great to see a younger generation take pride in their quality of work, and be patient and communicative.I had my scope mounted and zeroed in on my rifle. I also had some 1911 grips laser engraved and cerakote. They have earned my business going forward.

Great shop! Everyone is very helpful. Kevin helped me and was extremely helpful. This was my first firearm purchase and Kevin actually gave me a quick tutorial and was able to refer me to a great place to obtain my LTC! Thank you guys! I will definitely be back.

Dropped off my M&P to have the slide ceracoted in FDE. The turn around was incredibly fast with excellent work performed..

Absolutely amazing group of guys! Prices are great! And the work is incredible! I was blown away by the build they did! From cerakotes to builds. They have it all. So happy to have found them. Best shop in San Antonio!!!

Best gun-smithing in San Antonio the only company that would take on my AK-47 project. Great customer service!! Definitely coming back for all future projects

Now that I’ve moved to San Antonio, so glad that I have access to the best shop this side of Texas. Truly excellent crew, veteran run. 🇺🇸

I dropped off my AK for a change of color. Needless to say, the end result of my golden AK47 was absolutely mind blowing. Luke did an outstanding job. The attention to detail was phenomenal. Ill definitely be back in the future. Well done!!!👍

What an awesome hidden gem right in the heart San Antonio. Had them do a tiger stripe cerakote job on my rifle, came out immaculate. Great group of guys to work with. Veteran owned, and everyone that works there is a vet as well. cant wait to see these guys grow

I met Luke a while back at a gun show, and I just got around to stopping by his shop. Not your typical gun store, but they offer almost every gun service in the book. Had their gunsmith thread my barrel, and Luke laser engraved a slide that I wanted to gift to my son for his birthday. I also picked up a beautiful knife that I saw on their shelf while I was there.

Great people, great shop, great work. Can’t recommend them high enough. Definitely will be my go to shop from now on!

This was my first gun purchasing experience, so I dont another experience to compare too. The gentleman helping me was very patient and answered all my questions, but at the same time was very distracted. From what I understand. this is more of a shop, and not a retail space. Anyway, overall good experience and they gave me a great deal on my gun. They mentioned some kind of laser engraving and painting? of my gun which i may do down the road.

What a godsend Sinner Mass has been. I find myself trusting less and less people these days, but Luke and has team has restored a lot of that faith. Excellent work, efficient turnaround, and flawless work. Highly recommend you use this business for all your laser engraving, cerakote, and custom gun needs. THANK YOU ALL SO MUCH!!

Sinner-Mass is a great place to get a couple of projects completed. They were very helpful and professional even when I wasnt quite sure what direction I wanted to go in. The completed project is as beautiful as it is functional. At the end of the project my wife is very happy with the gift I got her. All in all the quality and craftsmanship is second to none and the prices are more than fair. I have nothing but good things to say about Luke.

Only giving 4 stars because I didnt receive my firearm back within the originally quoted turnaround time. They were communicative about it being delayed, so for that Ill give them props. Other than that, it was a pleasure doing business with these gentlemen. I had them Cerakote my AR15 and also laser engrave some magazines for me. Very unique gun shop in the heart of Alamo Heights. Will be giving them more of my business in the future.

A buddy of mine that is in the same unit recommended these guys to me. Very pleased with the level of detail and professionalism they put into their work. Had them Cerakote my lower, upper, and rail on my AR15. They offer a 15% discount for all First Responders, Vets, and Military! Great group of guys.

When I first saw the guns that Luke customized I was instantly drawn to his work. His patience, steady hand, experience, and artistic talent are apparent in his craftsmanship. He was easy to talk to and listened to my ideas about the distinctive modifications that I desired. Although my descriptions were inconsistent with the complicated terminology to complete the work, he easily translated the information to deliver a customized gun that exceeded my expectations. Truly an exceptional customer service experience.

Luke is awesome and has good prices at his shop. Luke’s knowledge of firearms and firearm customization is top notch and he has the best customer service I’ve seen in San Antonio. In a town where so many independent firearms dealers/shops are popping up, I trust the guys at Sinner Mass above all else.

Walked into Sinner Mass Fabrications and was totally impressed with the guns that were hanging on the wall. I had no idea these guns were custom made. The owners are a couple of military guys who have a raffle coming up to where you can win multiple guns as the months go by. These guys just want to help the veterans and truly care for the less fortunate. You get greeted by a friendly doggie named Gunner at the door. Awesome Experience!

Awesome job on almost all my stuff. Sig P230 all custom, AR15 all custom, Cerakoted my Tikka 308 and Swarovski Scope! And currently working on my 6.5 PRC Christensen Arms which I’ll be taking to Sonora on a sheep hunt! These guys and gals are solid and know what they’re doing. Custom jobs and Gun smithing! Thanks Sinner Mass.!Cheers

This was a first time experience for me. Everyone at Sinner Mass was very helpful and patient. They do exceptional work and have some very unique stuff in their shop. I now have my go-to gun shop in San Antonio.

If you are looking for a one stop gun shop. This is it! They took care of me from start to finish. Ordered an AR through their website, it was delivered within a few days, and they did a phenomenal job on the Cerakote job. They also ordered some specialty parts for me and installed them perfectly. Very satisfied with the turn around time, price, and professionalism. Will be back for more.

These guys are amazing! Their work is miticulous and amazing. No matter what has come up throughout the process they have done everything to deliver the best possible product. I would highly suggest using their services. Affordable prices as well!!

Luke did an amazing job. The quality and craftsmanship is unmatched. I always had good communication with SinnerMass and there was a very short turnaround time. I couldn’t be happier with their work. I will definitely be sending more projects their way in the future. Top-notch work from a top notch company and a fellow veteran.

Great place to do your FFL transfer. Everything is online and is quick, easy, and inexpensive. Also a neat place to browse while you wait for you background check.

Very cool shop! Impeccable Cerakote work. I will be bringing back my 1911 to have some gunsmith work done, and laser engraving. Awesome guys to work with, both Vets.

A great group of guys to work with. Had them work on my Glock and Ar-15, Cerakote work came out great. They also are quick, easy, and cheap for FFL transfers.

Im very thankful to have found this hidden gem. They laser engraved a present for my father, and also were well stocked on ammo at very fair price considering the crazy times.

Incredible work, fast turnaround, great price. Hands down the best around, I traveled 4 hrs one way to have my gun worked on by these guys. They are the best.

What an awesome place! They were the only shop that I called that had the ammo I needed at the time. Ended up just leaving my Glock with them for a single color cerakote and laser engraving. Highly recommend these guys.

Great group of guys at Sinner Mass. Outstanding customer service, great communication and honest - when was the last time you said all three things about a business? The quality and turnaround time on the engraving I had done was perfect. Veteran owned and operated (Semper Fi, brutha) and a hooya to the Army guys. Cant go wrong with Sinner Mass.

Awesome group of guys. Very friendly and were very patient with me with all my dumb questions. Had my fathers knife engraved. But now im wanting one of those cool looking guns!!!!

Luke did a fantastic job on my 1911. I had him gold plate (TiN titanium nitride) the slide, Cerakote the components, laser engrave the grips to give it a stippling effect, and they also did some gunsmith work to make it a 3lb trigger. Money well spent.

Took my G43x to get the slide cerakoted. I wanted to match the frame. When I saw the finished product, I was speechless. I knew it was going to look good because of the past reviews, but it was better than I expected. Now I have 100% confidence to let them work on my trigger along with any custom work I want done.

Really good customer service, very good pricing and their engraving is clean and has great detail. They keep you posted on the work their doing too which is nice to have that kind of communication.

Luke made a great weapon very personal. Beautiful job, on time, and a great price.Sinner Mass knows stuff! And does wonderful work!

This was the best price in town that I found and the work was perfect. I wanted to put a brake on my .308 rifle but I did not have a thread. A new barrel would have cost over $300 Sinner Mass threaded my barrel and mounted the brake for half that price and did a perfect job. Will be going back if I need more work done on a firearm.

I have been told that if I wanted any work done on my Glock, it should go to Sinner Mass first. They definitely lived up to the hype and I couldnt be happier with the finished product.My only issues was that my gun wasnt returned within the window that they gave me, due to some unforeseen building construction. But as far as communication, quality, and price goes, you cant beat em. Will be sending more projects to them in the near future.

Fantastic spot for some very cool mods. Awesome customer service and turn around time. Keep up the good work! Will be back for sure.

Really happy with how my G26 came out. I had Luke laser engrave my slide, and he removed the stock grip and stippled a much nicer grip on my frame. He also added a thumb paddle, which is a nice touch.

David was amazing and very helpful. Will definitely come back in the future. Thank you

I had tumblers personalized for my employees as appreciation gifts. Luke did an excellent job with the laser engraving and coloring. What a cool place! Very convenient location right off 410 and Broadway behind the Whataburger. Thank you!!

Came in to purchase some ammo and after talking to Luke I will definitely be coming back to get some work done from them. Awesome place!

Great business, great work, and even better owner. I tend to be pretty picky with a lot of things and I I was honestly a little unsure of what I wanted. However, I have them a general idea of what I wanted and they had my back. Definitely going to be doing business again!

Wow! is the best way to put it. Luke/Sinner mass did an outstanding job on my G17. I didnt know what I wanted so I called him on the phone and he took the time to explain it all to me. What customer service. Luke will be doing more work for me in the future. You should let Sinner Mass do your work you will not be disappointed. Give Luke a call today!

Sinner Mass was a great shop to have my gun shipped to. Mark was amazing at communicating when it arrived. Their custom laser seems awesome.

What an amazing experience purchasing my first pistol since moving to Texas. The staff was really helpful and knowledgeable.

Wow what an experience. Quality is amazing you can tell hard work was put into this. I couldn’t have dreamed of already badass sunuma Gun. I highly recommend this business & REMEMBER ... if it ain’t done by Sinner Mass it ain’t done right.

Absolute best in the business! Wish I could give 5000 stars. Thanks for the best and most thorough experience I’ve had.

Luke did custom hand stippling on my pistol frame, cerakote work on an upper, and ordered some parts I was missing. Quick turnaround, fair pricing, and a cool dude to work with. Ill definitely be a repeat customer and keep him in mind for future FFL/SOT needs.

Always amazing service. The quality of work is unmatched. Owner is always very honest about what his capabilities are.

Awesome Cerakote job at very fair price, super quick turnaround and great communication. Highly recommend anybody in San Antonio looking for anything gun related to check these guys out.

Very quick, easy, and cheap FFL transfer. Really cool shop. Will be bringing my husband’s rifle and pistol in for some upgrades (cerakote, stipple and laser engravings). Luke taught me quite a bit while I was there. Very knowledgeable and a pleasure to work with.

Process was simple, quick and they helped me with it. Good price.

Didnt buy a gun, but I was wanting to laser engrave some tumblers and pocket knives for the guys/gals at work for Christmas gifts. They gave me a very fair price and did some very detailed work that Im sure my coworkers will love.

I have followed this shop in IG for some time now and decided it was time to take my Benelli M2 Tactical in for some cerakote. I showed up to the shop on afternoon and I met with the owner Luke. We spoke about what I was looking for, we priced out the job, and I left my shotgun there to get some new color. Luke kept it touch with me throughout the process and the final product was exactly what I was looking for. Weather you know exactly what you want, or if you need a little help in the design these guys can help you out.

My boyfriend got his glock cerakoted and chain link stippled from these guys, we both love it. Luke was awesome to work with and even helped come up with a unique and creative design. Highly recommend these guys. I couldn’t have imagined it coming out any better. Already planning our next design.

Outstanding work done by these guys! Quick turn around and fair pricing! Will definitely be sending them more work

Not your standard gun shop. Just a group of Vets. that have a passion for guns. they did an FDE cerakote on the slide and frame, and they laser engraved my initials into my backplate as well. It is aesthetically flawless, and its a Glock so it shoots great. Once I get some tax return money, Ill be returning to have them modify the frame more to give it a more ergonomic feel, stippling and some undercuts. I also picked up a box of Fort Scott Munitions ammo. Thank you gentlemen!

Good people, easy to work with, outstanding craftsmanship. They stayed in constant communication so I always knew what was going on with my gear, so no surprises

Very cool shop. Bought a unique knife, and had them laser engrave it.

My g19 came out feeling like a glove. Nice deep undercut and chain link stippled frame. Thanks !

Hands down best cerekote, Laser engraving and service Ive ever had. When I first started discussing what I wanted with Sinner mass they immediately focused on helping me create ideas to customize the firearm of my dreams. Even though Im deployed they worked with me and made sure that I was getting exactly what I was paying for. The result was a beautifully cerekoted pistol slide and a exact lazer engraving of the image I sent to them. Even when FedEx lost one of the parts I had customized they made sure the package was insured and replaced. Nothing but absolute love for Sinner mass highly recommend their work.

Great attitude and ready to help! Highly recommend

Completely satisfied with the entire experience! communication was top notch and level of service was as good as it gets! very pleased!

Great products and advice. All around great experience .

LUKE YOU ARE MY FATHER... YOU DID an Absolutely fing amazing job.. customer service and lead times were above and beyond by far the quickest I have ever delt with. Would recommend to anyone for any of the service that they offer and then some, these guys do it all and DONT drop the ball. Will be back for more work!!!

I took my Tavor to them after Bullitproof Arms botched my trigger install and charged me twice for it. They fixed the trigger and hasnt had any issues since. I suggested him to my other friends with is the best review really

I had SMF do my Glock 19 up with cerakote, stipple and laser engraving. They produced jaw-dropping work. Luke kept in touch with me with progress pics and had a super fast turnaround. They will definitely get all of my custom gun work in the future.

I bought my glock from them and had a great experience with the FFL transfer. Shopped around and found their prices could not be beat. Very friendly folks to deal with.

Excellent work done, great pricing, quick turnaround time, and flawless artistry performed on my G43x. Im a big time horror movie fanatic and they really transformed my gun to show that in a unique and feminine way. Not to mention Mr. Hamilton is a bit of a looker, 10/10 would would hit that, and also get another gun from this company.

I bought a gun for my husband and used Sinner Mass for an FFL transfer because they are Veteran owned, and my husband is a Vet. Only drawback was that they had to close the store on the day that I wanted to pick it up. But Luke went out of his way to meet me early in the morning the following day before the shop was open for business.

Did an amazing job on my Glock 23. Exceeded my expectations. Go visit their social media to check out the quality of their work.

Great new gun modification shop. Fast friendly service. I bought my Glock and sign from them and the FFL transfer went very smooth. Will be returning for cerakote and laser engraving.

Good customer service, great work on their customization, they are very good on giving out ideas on your builds, defenetly will be doing more business with SinnerMass not to mention you can’t beat their great work with their fair prices

Quick and easy FFL Transfer. Preferred FFL for classic firearms making it super easy. Near instant replies to messages and really relaxed shop with electronic paperwork making it that much easier to finish the sale. Ill be back to get some custom work on my Glock for sure.

Quick, easy, and inexpensive FFL transfer. Will be back to get my G28 stippled and cerakoted.

Awesome new gunshop. Great people and great custom work!!

Turn around was very quick, and Luke’s work exceeded all expectations. Will be returning soon.

Had some work done on my Glock 19 and Sig sauer p320. Luke did an excellent job with the multi cam cerakote and also did a phenomenal job with stippling my frame. Quick turnaround time and very fair prices for the quality of work provided. Will be returning with a few of my hunting rifles for sure.

All of the modifications I needed to be made for my AR and Glock came out flawless. I had my grip stippled, a custom slide added, and had both firearms cerakoted. I also had him put a custom trigger in the AR. I will be bringing back my Sig Sauer for a laser engraving. Highly recommend
