No one's got anything?
I did a little more research and it seems that the 92A1 has a little different slide than the m9A1.
The 92A1 slide will apparantly fit on a berreta 90 two, but not onto a regular m9 or 92fs. I guess this is because it is slightly wider to accomodate a recoil buffer in the slide like the 90 two has. Also it seems that the 92A1 has a removeabe dovetailed front sight and comes with 17 round mags. In addition to those things listed, the 92A1 has a rounded trigger guard intead of a squared one. And of course the rail.
Now the m91 from what I am seeing is the exact same as the 92fs or m9, but has a rail on it. Also when you purchase it, they include mags (15 round) that are coated with a special coating to resist sand, for dirty enviroments. Also the m91 has a beveled mag well for help with faster reloads under stress. Also the m9A1 has checkering on the grip.
I know I answered my own question, but thought this info may help others who may not knwo the difference. Becuae I found a lot of junk on the net, with people saying there is no difference between the two. So now you know. And knowing is half the battle! Now I just need to decide!
