Pistols are handheld firearms designed for one-handed use, typically cartridge-based and compact enough for personal defense, sport, or duty. The two main categories are revolvers, which chamber cartridges in a rotating cylinder, and semi-automatic pistols, which feed from an internal or detachable magazine and automatically cycle after each shot.

History: Pistols date to the early modern period, evolving from matchlock and wheel-lock designs to cartridge-armed models in the 19th century. Revolvers gained prominence in the 19th century with early models from Colt and Smith & Wesson. Semi-automatic pistols were introduced in the late 19th and early 20th centuries by designers such as Browning and, later, numerous manufacturers. In the late 20th century, polymer-framed pistols from manufacturers like Glock broadened civilian and professional use.

Design and operation: Revolvers use a rotating cylinder to present a fresh cartridge to the hammer for each shot. Semi-automatics feed cartridges from a magazine into a chamber and use the energy of firing to cycle to the next round. Common components include the frame or receiver, barrel, action, trigger, sights, and safety devices. Variants differ in mechanical operation, including short-recoil and blowback designs for semi-automatics.

Uses and regulation: Pistols serve in self-defense, sport shooting, law enforcement, and military contexts. Legal requirements vary widely by country and jurisdiction, including licensing, background checks, and storage rules. Responsible use typically involves training and adherence to local laws.

Safety: Treat every pistol as loaded, never point it at anything you do not intend to shoot, keep your finger off the trigger until ready to fire, and store firearms securely and separately from ammunition.
