Back in '98, we did some life cycle testing for the INS with their Beretta 96D in .40 S&W. I really didn't care for the 96D much, but I found their (the INS) choice of ammo to be excellent; the Remington Golden Sabre .40 S&W +P+ was very impressive.
During the course of our testing we broke three of the 96Ds. One was minor, the front sight fell off. The other two were serious. One suffered a cracked frame, another had the slide retaining pin fail and the slide, barrel and recoil spring went down range, leaving me holding the now barren frame. All failures occured between 11,000 and 14,000 rounds fired.
My regards,
