My 19-2 2.5 inch (P&R) has a few hundred 158grn LRN at 800FPS (Minor power factor) and has not been an issue. Practicing for ICORE, it is one of my backup guns.
With 98% blue and great mechanical condition, I paid $400 for it last year. Came with correct grip and a little tiny bit of rust.
Well worth it at $400, $500 seems high.
Surprised how accurate it is at 25 and 40y. Amazing little gun.
I've had my PSA AR9 for a few months, about a 1,000 rounds of my own reloads down range. ZERO issues.
I changes the hammer/trigger springs out, added a heavy buffer, and a scope.
Very accurate and reliable. I want another.
