I have owned 9 Glocks. I currently own 4 so I am a GSSF Glock man. I have never sent any pistol back to Smyrna for any reason. I had several FTFs and a whole lot of brass in my face for the first time in over 15 years of Glock shooting. I thought it might be the trigger bar. However, the 4256-1 that it came with I was sure they would change but they didn't. I was expecting for it to return with a 4256-1- but it did not and came back with the original -1. I haven't got a chance to give it a dance but I will shortly. I know several of you were wondering which bar mine would come back with and I was surprised because there was no explanation to what they did to the gun. I got it late this evening so I will call them tomm to find out what the problem was. Wanna kill these ads? We can help!
