I can't speak to the Inox version and I am by NO means an expert, but...
I have carried the M-9 several times overseas for my uncle and was one of those that always bashed it because it wasn't a '_______'. Fill in the blank.
After performing horribly on the qualification range at work one day, I manned up and realized that I would need to make friends with this firearm.
I purchased my own 92FS and started over from square one. I relearned how to shoot it on my own. Depending on your MOS and unit, you don't go shooting very often so marksmanship proficiency is "on you".
After putting a couple thousand rounds through my 92FS, I have to say that it has become one of my all time favorites firearms.
I feel pretty good about my performance with it now and had to eat crow to one of my buddies in the unit after pervisously bashing the design. Now, it is one of the two guns that always goes with me for practice. My home defense first choice is my 92FS with the Corbon Powerball, next is a G27 right behind it. I trust the protection of my most important gifts (family) to those.
When I was overseas I did not have any problems with its operation, although some have complained about it. My issued side arms operated just as they should, even in the fine talcum powder sand. I brushed it off a lot and tried to minimize the CLP.
I am glad I got mine.
