The Glock is a lightly worn (mostly holster wear) G21 gen-2 from 1993. I stripped it, and everything looks good. I put about 100 rounds through it at the range without any problems.
I'm pleased, in spite of the size and weight. It's not exactly concealable, but I really like being able to carry a pistol with 14 rounds of .45 stopping power. Remarkably light recoil.
From what I know Glocks are solid. Taurus’s on the other hand...
