So after 100-150 rds last night at the range, making that 4-500 in the last week (Got a lot of ammo as a gift). After (finally) cleaning it last night, to my horror I noticed a left over plastic piece, which appeared to have snapped off of the frame. I'll be the first to tell you I'm a novice handgun enthusiast and shooter, coming from a primarily trap shooting childhood, so excuse how dumb/uninformed I may be. I just could use a little advice! I know glock is supposed to be good with customer service and replacing broken parts or whole guns, but I'd like to know what I'm talking about while describing the issue, so without further ado, here are the crappy pictures I took ^^the culprit??? Any help on what exactly that is, as well as my next steps with block/local smith would be much appreciated! Wanna kill these ads? We can help!
