This 460 XVR features a fluted barrel sling, integral picatinny style base top and bottom, forged hammer and trigger, traditional pinned sear, and internal lock. The Smith & Wesson model 460XVR (X-treme Velocity Revolver) is so revolutionary that it required an entirely different designation. From hand-cutting and fitting to fine tuning for precision, these firearms are top performers. Products from the Performance Center are the ultimate expression of old-world craftsmanship blended with modern technology.
