Took my brand new Walther in to have night sights installed, was told that he accidentally broke them and had to order a new set.After several days the new sites were installed and I picked up the gun.Was told that he accidentally lost a part to my factory sites, I had no plan to use the factory sites so I wasn’t overly concerned at the time.Paid for the install and left.I few weeks later while at the range the rear site came loose.Took the gun to another gun smith and was told the night sites and my weapon were damaged from the install and that they needed my factory sights to repair the gun. (The missing peace that was lost was what they needed)Now my slide has to be sent into the factory to be repaired and I have to purchase a new set of sights(3rd set).I would not recommend this Gunsmith to anyone!
