A "striker-fired" firearm is a type of handgun that uses a striker mechanism instead of a traditional hammer to ignite the cartridge. In this design, the firing pin is spring-loaded and is released directly by the trigger pull, which simplifies the internal mechanism and often results in a lighter and more compact firearm. Striker-fired pistols typically have a consistent trigger pull for each shot, which can enhance accuracy and ease of use. Popular examples of striker-fired handguns include the Glock series and the Smith & Wesson M&P line, both known for their reliability and widespread use in law enforcement and civilian markets.
