I finally took the RM380 to the range this afternoon.
I shot 20 Hydra Shoks, 24 Hornady Critial Duty, and 42 Walmart Winchester White Box FMJ's. No failures of any kind and the slide locked back on every last shot. I used both of the supplied magazines.
After I got used to the trigger, I was able to shoot some descent groups, 3" to 4" at 7 yards. Mild recoil, I could shoot it all day.
If it had real sights, I think it would be very accurate.
