I've just gotten a Glock 34 to shoot IDPA with it. It makes a rather annoying squeaking noise when racking it. Took it apart and is clear that the recoil spring is touching the barrel and leaving marks in it. Called Glock and was told that is a pretty common issue. Anybody out there experienced the same? Does it affect performance? Solutions? Cheers, Julio By the way, got a Comp-Tac paddle holster with tabs. Great holster indeed !!!
