G-19
I stake my life on it. I owned and carried a G-21 for 4 years in the early 90's, that Glock took 38,000 rounds and never had an issue. It did need a new trigger, but after 38,000 rounds I didn't see that as an issue. Had gotten away from Glocks for some years, carried a Sig 226, then 229, then H&K USP's in .45 (full size, then compact), then went to a Kimber Ultra Eclipse II until I injured my knee. That's when the need for a lighter pistol arose, so I picked up a Glock 19 and I'm completely back in love with them, and I trust the Glock (as all the other pistols mentioned above) with my life.
