A flat-ended, nearly cylindrical bullet designed for cutting full-caliber holes in targets. Especially favored in light, target loads. A wadcutter is a special-purpose flat-fronted bullet specially designed for shooting paper targets, usually at close range and at subsonic velocities typically under approximately 900 ft/s (274 m/s).
Wadcutters have also found favor for use in self-defense guns, such as .38 caliber snub-nosed revolvers, where due to short barrel lengths, maximum bullet velocities are usually low, typically under 900 ft/s (274 m/s), and improved lethality is desired. Wadcutters are often used in handgun and airgun competitions.
A term coined by gunwriter Robert T. Shimek to denote the modern breed of 9mm Parabellum auto pistols of recent design, usually featuring high magazine capacity and a double-action trigger mechanism or other modern ignition system (e.g., the squeeze-cocker of the Heckler & Kock P7 series or the Safe Action of the Glock).
Wonder Nine refers to any semi-automatic pistol that is chambered in 9×19mm Parabellumand has a staggered column magazine, as well as a double-action trigger for at least the firstshot. The term was coined by firearms author Robert Shimek, and became popular in Americanfirearm-related magazines during the 1980 by those advocating for their use by police forces.
