In my experience , my P16-40 limited Yr 2000 model working very fine ,this also heard the same as other shooters mentioned , but my P13-45 limited Yr 2003 model , always had 1 or 2 jam out of 50 rounds factory loads , the extractor break at 2000 rds , ejector breaks at 3000 rounds , then I replaced with a solid stainless steel parts also I reduce the power factor of loads by 10%, the gun now can chew all bullets from 180 grs to 230 grs . To be fair , I also heard some shooters mentioned other named brands even more expensived ,out af the box cannot shoot , jam ...jam... jam.... It mostly depends on how lucky you are .
