Bought this RIA 1911 in 45 a few months ago. Have about 600 rounds through it with 1 failure. Slide didn’t lock back after last round on a bad gi mag, no failures from any new mags or anything else. Targets my best grouping at 20 yards from second time ever shooting (only been to the range twice) What’s your guys thoughts on my purchase and grouping?
