Our X-Frame holster is designed to carry these larger handguns with a 4 ½” barrel. It has two horizontal rows of tight woven elastic cartridge loops spaced further apart in the vertical direction to accommodate the longer cartridges of the S&W 500 and 460. The Ammo cover is fixed with high quality hook and loop materials. It has a 1” heavy nylon webbing thumb strap and high quality side release buckle to secure the gun into the body of the holster. The trigger outline is what makes this holster what it is; giving more allowance for the larger frame and slightly different shaped trigger guard.
