Like new Kel Tec P17. Serial number is an early model but was sent in for service and basically rebuilt with all new/upgraded parts. Barrel, trunnion, and other assorted parts are new. Firearm was test fired to verify functionality. Has the Crimson Trace optic and slide. This is the original optic and slide configuration. Kel Tec has since switched to the Viridian optic. Includes the factory slide and one extra magazine.
