This is a very nice lightly used Ruger PC9 carbine chambered in 9mm Parabellum.  Mechanically this carbine works great and is an awesome shooter.  This rifle takes Glock type 17 or 19 magazines.  This is a takedown carbine and can be split in half for ease of carry.  It also has a threaded barrel. Comes with one original 10 round Glock magazine.
