RJL123

Thanks for the info. Gun shoots fine. It was puzzling because the rest of the gun shows decent quality control in the machining and finish. Have seen this on older 23s and 19s but my 36 doesn't show it at all.

Hi you guys. This is first time here. I am wondering if anyone has noticed scoring on the breechface of any of the various Glock models. These are very visible and run vertically on the face. I have never seen any thing like them on any other gun and was wondering what they are from. I can't imagine that they are from the brass case sliding on it. Anyone know? Thanks.
