I recently sent in a Glock slide for some custom machining. Best decision I ever made, pertaining to custom work, was to go with Go Machining. There a couple of places much much closer in the Southwest but you can see from his pictures he does outstanding work. When I got my slide back the work was incredible. I almost didnt want to have it painted. The surface wasnt marred by a vise, the cuts were clean... He got it back to me faster than local places were quoting by almost a month. Book with Jerry before other people realize how good he really is and his lead time becomes extended!
