ruger pc carbine

The Ruger PC-9 Pistol Caliber Carbine is a blowback centerfire semi-automatic pistol-caliber carbine manufactured by Sturm, Ruger & Co., designed as a companion to certain Ruger P series semi-automatic pistols, using the same 9 mm Parabellum and .40 S&W caliber cartridges and magazines of the P-Series pistols.
Both the PC9 (the 9 mm version) and the PC4 (.40 S&W version) are modelled after Ruger's highly successful Ruger 10/22 rimfire carbine. It is intended as a shoulder-braced weapon for law enforcement use, although it was available for sale to civilians as well. The intent is that an officer will carry a Ruger P-Series pistol as a sidearm, and keep a Police Carbine available (for example, in the patrol vehicle) as a more offensive weapon if needed. Since the PC-9 has a 16-inch (410 mm) barrel, it provides more muzzle energy with the same ammunition used by pistols which often only have 4-inch (100 mm) barrels (see internal ballistics), thus better stopping power, accuracy and effective range than pistols.
In 2007, Ruger discontinued production of the original Police Carbine, citing low demand. More than ten years later on December 29, 2017, Ruger announced the reintroduction of a new upgraded 9 mm takedown model called the Ruger PC Carbine with the PC now referencing the old Police Carbine name and the product descriptions calling them Pistol Caliber Carbines, which has a 16.12-inch (409 mm) threaded barrel and accepts not only the Ruger SR9 pistol magazine, but also magazines from Glock, Ruger American Pistol and the new Ruger Security-9 pistols via interchangeable magazine well adaptor inserts. In early 2019, Ruger introduced a variant PC Carbine model with free-floating M-LOK handguard, and also reintroduced the .40 S&W caliber.
