A pocket pistol is a small, concealable handgun designed to be carried in a pocket. Pocket pistols are typically chambered in a small caliber, such as .22 LR or .380 ACP, and have a short barrel length, typically less than 3 inches.
Pocket pistols are popular for self-defense because they are easy to conceal and can be quickly drawn from a pocket. They are also relatively inexpensive and easy to maintain. However, pocket pistols can be less powerful than larger handguns, and they may be more difficult to shoot accurately.
