For an officer considering a backup gun, one of the major factors is weight. Smith & Wesson and Taurus have addressed these issues in the small-frame revolver by replacing heavier steel frames with lighter aluminum, titanium, and scandium metals.
Most officers have incorporated the .22 at some point during their careers or may have become familiar with it during their youth through informal target practice and plinking. For those who want to improve their qualification scores and increase their confidence on the street, an effective next step is a dedicated target pistol designed around the .22 cartridge.
The .380 ACP round is much shorter than either the 9mm Luger or the .38 Special, creating the ultimate deep concealment package with six to eight rounds of ammunition. This exceeds the average five-shot, deep-concealment revolver by a few potentially life-saving rounds.
