Shot shot? Anyway 597 with 10 and 30 rnd mags and 555 runs ok in mine
The rem 30s' do have last shot hold open, you have to bend out the small black tab until it hits the lever inside the gunI've shot Federal 525 with the 30 rounder and no issues. The 30 rounder does NOT hold the slide open on last shot, just FYI.
