I have about six Sigs. The 220 is my favorite. They will do it quite often. I have only had one that would do it every time and up to 1500 rounds. That was a rebuilt Spring Field 45 auto. 1911. Also I agree the Ruger 45 is about flawless. Between practice and matches I usually fired about 1500 rounds per week. I got burned out on relaoding and gave it up a few years ago.
