I have 1 in 40 and 1 in 9mm , the 40 is a flame thrower but has NEVER had any problems or malfunctions .The 9 had to have the firing pin stop changed because the extractor was clocking , no more trouble
Great guns IMO
Great little 9mm, except mine is back to SA to have the ejector pinned. Not pinned from the factory on a $1,000 gun. It would shoot 25-30 rounds before the ejector would rise and lock it up. I could tap it back down with a plastic hammer and shoot another 25-30 rounds. I'm not happy with SA QC! There are lots of comments on the 1911 forum.
