Got it with less than fifty rounds through it from the second owner in 2003. It bled the first two owners.
I have upwards of ten k through it, shot it in IDPA CDP, and have carried it daily since I got it.
The only fail I recall was ammo related.
The only time I ever doubted it was after it was taken by a POS deputy during a traffic stop(stupid MI laws). I had to reconfirm it was dead reliable.
I hate Glocks....I only own eight ish...
I bought a brand new Glock 21 the day after I shot a friend's.. (mine's older ..Gen. 2 or 2.5-I've had it awhile) I liked the idea of a large capacity .45.
Though I bought a Lone Wolf barrel for mine ( to safely shoot lead bullets) I still haven't shot it much,
& don't consider it my favorite non 1911 in 45acp.
My favorite would be a W.German made Sig 220.. or for high capacity a Para Ordinance P-14 ( not a 1911, more of a 2011) in SS I bought new on a "closeout sale" shortly after Para closed their doors. MY P-14's been flawless in it's performance.
