I shot my SR40C for the first time a couple of weeks ago and had 5-6 stovepipes out of 75 rounds. I was using my reloads and they chrographed at 800 fps, which is a little light. They work fine in my Glock, but Glock's will take about anything. I fired about 1/2 box of factory 165 fmj and had no problems. They also seemed to recoil a little more. I'm thinking I need to step up my reloads a little to help the problem.
