After last shot slide will lock open but Nighthawk mags won’t drop free. SA mags work fine. After pull NH Mag out and then re-insert it will drop, it seems to only happen when mag is inserted and slide locked to rear either by hand or last shot.
Runs great with factory and reloads. Does need a different hand guard to use suppressor as the factory guard has the be removed to remove the break and it is too narrow to fit over a suppressor.
