Great gun, one of my favorite 9x19mm's. The main duty for my Inox is car gun and range gun, but it doesn't get used often for either purpose. I have CCW'd the 92FS without problems, though I'll readily admit CCW is not it's greatest strength as it is a service sized handgun, not a compact. It's strengths are that it feels good in the hand, has a reliable open slide design, it's easy to work on, parts are incredibly easy to find and it's accurate. It also carries 20+1 with the latest Mec-Gar mags, but I typically use the factory 15's with Wolff +10% springs. In addition to these strengths the military M9 and commercial 92FS is made with high quality parts, (except for the ones with plastic).
Weakness are that it's a little large for the caliber, the trigger return spring can break and the front sight of the 92FS model is not dovetailed. The trigger return spring problem is easily fixed with a Wolff INS trigger spring unit which will end the breakage problem. (Taurus PT92 has the same problem). Also, if you are shopping for one avoid the plastic parts models and hold out for an (almost) all metal gun, as they have started making those again.
A couple people mentioned the slide safety getting in the way when racking the slide, this can easily be overcome by having your thumb and index finger slightly below the safety. Also, if doing it fast without looking, it can be overcome by pulling slightly up when you pull the slide back.
And a some people also mentioned that up for fire is stupid. Well maybe on a frame mounted safety, but the 92FS has a slide mounted safety, therefore down for fire would be stupid. It is the same as most any other slide mounted safety, such as the one on the S&W 5906. If you think that pushing a slide mounted safety down with your thumb is easier than pushing it up, you're goofy.
