All rounds fired about 250 no FTE. Even with the Scott munitions. The slide only locked back twice . Calling ruger to replace magazine. Hope it’s not the gun. I have a 12 round mag on order . As for grouping its a lot better this time . But past 7 yards it’s tough. I think it’s me and the trigger. In order for the slide to lock back on an empty magazine I have to slightly push up on the mag. Also noticed racking the slide on the first round sometimes it would pause before snapping a load. Seems like some rounds get caught on the barrel possibly. And even if I pull the slide fast and hard. But that’s not really an issue as the gun works fine except for the last round slide open.
