I received mine about two weeks ago and shot it for the first time last week using an assortment of 230 grain FMJ. Had no issues with any of the ammunition and the pistol functioned well with all OE SA mags, but for some reason it didn’t like a CM power mag. Fed well with the mag, but the slide didn’t lock back on the last shot. CM mag functions fine in my MC Operator and DW Bobtail. Other than that, it is a pleasure to shoot.
