The Beretta Nano is a sub-compact, striker-fired (Beretta’s first), locked-breech, recoil-operated, semi-automatic pistol. It holds six rounds of 9mm in its single-stack magazine, with one in the chamber—of which will fire regardless if a magazine is inserted or not. There is no magazine disconnect safety. Meaning if the chamber’s hot, the Nano’s gonna fire.The cool thing about the Nano is its interchangeable frame. It has the potential (on paper) to be a great carry gun for women.
