When I have a CCW that malfunctions, I get rid of it.
I have found no matter how many trouble free rounds I shoot through a gun, after a malfunction I can never trust it.
As for Glocks, I have yet to own one built after mid 2009 that has been reliable. Glock used to be "perfection" and then someone apparently tried to fix something that wasn't broken, I guess. I'm not really sure what they changed but something did change.
That said I have had two revolvers lock up on me so I can't necessarily say I trust a revolver just because it's a revolver like some have stated early on in this thread.
I have had all sorts of brand name guns malfunction on me, so I don't just trust a gun just because of it's name either. I only trust a gun if it has proven reliable through some solid range visits and various "tests" if you will.
I'd rather have it and not need it then need it and not have it.
