More than ten years later on December 29th, 2017, Ruger announced the reintroduction of a new upgraded 9 mm takedown model called the Ruger PC Carbine ("Ruger pistol-caliber carbine"), which has a 16 inches 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.
