The Beretta 90-Two (usually called the "dash-2" for short) was an attempt to improve upon some of the complaints about the original M9/92FS series firearms. It added a standard picatinny rail, internal buffer for increased recoil absorption, dovetailed front sight, captured guide rod, and new/updated safety switch/mag release/trigger bar/hammer/slide/frame to change the overall look of the gun. The biggest change of all however was the grip. The 90-two has a polymer grip sleeve offered in two sizes: standard and slim. The grip is probably the most controversial aspect of this pistol; some like it and others (myself included) don't particularly care for it. The best way to describe it is "slippery." Stippling and adding some grip tape help but it still can leave you searching for more.
Pros:
[*]100% reliable so far (about 700 rounds)
[*]Good sight picture
[*]Balances well in the hand
[*]With the D spring, DA pull is very good (smooth, not too heavy/light)
[*]Accepts standard lights/accessories
[*]Finish is beautiful, it's a very good looking gun in my opinion
[*]Accurate firearm (the group I shot was evidence of this, although I probably couldn't do it again if I tried!)
[*]Comes with 3 17 round, well made magazines
[*]Price––I paid $499 for mine with night sights and also recieved a $50 mail in rebate
[*]Very well built firearm
[*]Low percieved recoil
Cons:
[*]SA trigger could be more crisp
[*]Very little aftermarket support
[*]Grip is slippery
[*]Made in Italy only
[*]May be discontinued in the future
Overall, it's a very good gun with one flaw (grip) but that wouldn't keep me from recommending it. To me, any gun that is very reliable and accurate will always be a good gun in my book. That said, if money isn't part of the equation, I'd proably opt for the 92A1 which incorporates many of the same features but keeps the standard 92 series grips.
Here's a video demonstrating some shooting, an 'accuracy test' (again, the gun is undoubtedly more accurate than the shooter in this case), assembly/dissasembly, table top review, and some chronograph testing.
