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.
The Beretta 90-Two is a large-frame semi-automatic pistol chambered in 9mm and .40 S&W. The 90-Two stems from the M92 (aka the M9, the US military’s standard issued pistol) and shares several features with the model such as an open slide design, so the barrel is shows through. It has an external hammer that when cocked back changes the trigger pull from a double-action (long pull) to a single-action (short pull). Its ambidextrous safety also acts as a de-cocking lever. A second safety feature is a visible automatic firing pin block that prevents discharge if it’s accidentally dropped. And three-dot fixed sights.
The newly designed frame of 90two pistol ensures trouble-free insertion and holster extraction, thanks to its rounded and truly snag-free surfaces. Inside the frame, near the disassembly lever, a metallic recoil buffer reduces the impact of the slide assembly against the frame during the shooting cycle. By redistributing the stresses, the recoil buffer increases the service life of the firearm.
Trigger guard is also rounded to ensure, when firing with two hands, the correct positioning of the supporting hand.
