The Tanfoglio STOCK Master brings together the ultimate set of features for today’s Production Division Shooter. Available in both small and large frames, as well as Tanfoglio’s full caliber selection - there is a STOCK Master variant to fit almost every shooter. The Defiant STOCK Master takes the frame of a STOCK III and combines it with the highly desirable features found on the STOCK II. Full Conical Bull Barrels with Semi-Polygonal rifling come standard and are lengthened to match the length of the STOCK III frame. The Defiant STOCK Master uses a lightened slide like the one found on the Limited Custom to quicken cycle time and lockup.
