Here's another, more generic write-up on Beretta 92s. It doesn't go into super detail but covers all the common variants and some not-so-common ones. One trend you will see is that most of the following is discontinued, which is a good indicator of Beretta's shift in focus to the 90two and PX4 Storm. My goal is to render the Beretta forum a ghost-town, void of any questions! Seriously though, I hope this helps. Of course, it's a work in progress and please inform me of any mistakes - you won't hurt my feelings.

Operating System Designations

- F - 92, 90wo, 96, 98, 99: DA/SA, slide-mounted safety / decock dual-function lever: flipping the lever down decocks hammer (if on SA) and places weapon on safe – user manually flips lever up to fire position
- G - 92, 90two, 96, 98: DA/SA, slide-mounted decock-only lever: flipping the lever down in SA decocks hammer and lever returns up to the fire position – no manual method to place weapon on safe
- D - 92, 90two, 96: DAO, no safety lever: external hammer spur removed (except on 90two), comes with lighter D-mainspring
- DS - 92, 96: DAO, slide-mounted safety-only lever : external hammer spur removed, flipping the lever down places weapon on safe – user manually flips lever up to fire position
- R - 93: SAO select-fire, frame-mounted safety and selector switch assembly: large front-facing lever selects 3-rd burst or semi-auto fire, smaller rear-facing lever adjusts manual safety (down for safe)
