I bet my life on a blue 92FS for quite a few years. Also used it in instruction. When I retired and turned it in, I had put approximately 23,000 rounds of Federal factory hardball, WW hollow points (duty ammo), and Federal hollow points (also duty ammo) through it. No malfunctions other than a few dud rounds but that was the factory's fault, not the pistol's. (When your agency buys 7,000,000 rounds of 9mm each year, you'll hit a few duds now and then.)
One of our armorers did a test on a new Beretta 92FS blue steel, putting approximately 70,000 rounds through one, with no breakages of any kind. This was done over a period of several years.
I bought a new one and have put approximately 2,000 rounds through it without any failures. (Ammo ain't free anymore.) Although I'm a died-in-the-wool Colt's .45 fan, I'd bet my life any day on the Beretta 92FS. Accuracy is most important when it gets down and dirty.
FWIW. J.B.
