I used to be indifferent (at best) about Glocks, but a friend sold me on the, "Most issued military sidearm (G17), and most issued police duty weapon (G22), so you should learn to use one," argument. Some wisdom there, I suppose. Regardless, I found a Gen 2 G22 (still NIB) for a song, raced it out a bit, and started using it for USPSA. I have a few dozen matches under my belt with it as my primary Production gun, and it has only let me down twice. Once was after the install of a Ghost 3.5 bar and springs, and it basically bump-fired an entire magazine at NC regionals. The other was last week, when I pulled it out of the safe to load up my range bag, checked it, went 'hammer down', and it didn't go click. The spring in the trigger group had sheered off...after about 9,800 rounds. Time to replace the springs anyway.
Had to roll to the backup: a RTF2 G17, very slightly raced out, mainly my wife's USPSA gun.
*--As a caveat, let me just say that there's no way in hell that I would carry or use one of the above Glocks for self defense in any capacity other than a last resort. I think there's too much imagined liability about 'modified' guns, blah, blah, blah. Maybe it's paranoia, but I imagine an overzealous DA having a field day with a 5+ lb stock trigger modified to 3.5 lb. I'll have enough trouble explaining why the baddies all have two rounds to the chest, and one to either the brain casing or pelvic girdle...
ETA: BTW, the RTF2 is shit, IMO. It's more prickly than anything else, and the few times I've used the G17 in competition, it's massively fucked up the shirt I was wearing. I'd stipple it like my G22 if she'd let me, but she doesn't want the kevlar callouses my stippling builds up.
