I've always dry fired my Colts. Now I dry fire my SA. I've never had a problem dry firing a centerfire auto pistol until my Beretta 92FS Centurion. I dry fired it perhaps 200 times after running about 300 rounds through it to smooth it out. One day while driving home through a very rural area on the levee I decided to pull over and dump a few mags through it. Click. Nada. Firing pin broken. Good thing I didn't get in a bind and need it. All I shoot now are my Colt and SA .45's and two bhp's. I've never been overly impressed with the 92F series, and that's after well over 10k rounds. BTW, changing out a 92FS firing pin is a PITA compared to an M1911 or P.35.
