The Beretta Nano 9mm subcompact is an innovative little carry gun, bringing you a reliable every day carry (EDC) gun small enough to carry without being cumbersome yet powerful and trustworthy enough to bet your life on. The Beretta Nano 9mm is also a unique pistol polymer subcompact pistol in that you can easily swap the frame without need of buying a new "gun". Unlike other polymer pistols that the serial number is imbedded in the frame, the Beretta Nano's fire control unit is serialized. This is an excellent feature in the event you scuff or ding your existing frame or simply wish to change its color. Beretta offers replacement frames in various colors like Black, Rosa(pink), and FDE or Flat Dark Earth, and these frames can be shipped directly to your house without the need for a background check. The Beretta Nano is a single stack capacity lending to its thin frame. The trigger is similar to other striker fired triggers on the market, albeit much smoother. Unlike similar guns, the Beretta Nano 9mm has user adjustable sights and the magazine release is reversible for left handed shooters.
