Lets see......I've had mine for over ten years and I couldn't beging to guess at the number of rounds that have been fired through it. I have had zero problems with it and no parts breakage. I did recently replace all the springs and locking block, for no other reason than I thought ten years was long enough. I was a recreational shooter, then a reloader and no a LEO (who loves to go shooting) so I'd say the number is probably 25, 000 give or take a 1,000. I've put over 2, 000 rounds through my 92FS this year alone.........even after switching to a Sig P220.
