I just got back from the range after feeding my RO an exclusive diet of 230gr JHP's from Georgia Arms. I had 3 nosedive into the ramp trying to chamber the first round, out of about 100. It might have been mag related. I didn't single out the mag. :embarassed: But once the first round was chambered, it never had an issue cycling. I love this gun, though. I'm way more accurate with this thing than I am with my beloved M&P, however my M&P fed these JHP's just fine all day. Anyway, just thought I'd pass on some firsthand info. I'll try and pick up a couple of new mags and keep pluggin' with it. It was a beautiful day around here for range trip, and my girlie friend and I had a lot of fun.
