pc carbine

The Ruger Police Carbine is a semi-automatic blowback pistol-caliber carbine manufactured by Sturm, Ruger & Co., designed as a companion to Ruger's P-Series centerfire pistols and using the same ammunition and magazines of the P-Series 9 mm Parabellum and .40 S&W caliber pistols.
Both the PC9 (the 9 mm version) and the PC4 (.40 S&W version) are patterned after the highly successful Ruger 10/22 rimfire carbine. It is intended as a shoulder weapon for law enforcement use, although it is 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 an offensive weapon if needed. Since the Police Carbine has a 16-inch (410 mm) barrel, it provides more stopping power with the same ammunition used by police pistols which often only have 4-inch (100 mm) barrels (see internal ballistics). The Police Carbine also provides additional accuracy and effective range over the pistol.
In 2007, Ruger discontinued production of the Police Carbine citing low demand. More than ten years later on December 29th, 2017, Ruger announced the reinstatement of the Police Carbine with a new upgraded 9 mm takedown model called the Ruger PC Carbine, 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.
