I am contemplating getting my 460 S&W 5-inch barrel muzzle-brake X-frame modified for moon clips. The advantage would be being able to use semi-auto 45 and 45 Winchester magnum, or any other semi-auto 45 caliber cartridge so equipped. Besides versatility and end-time cartridge flexibility, one more advantage is assured ejection of all shells at once. TKCustom.com is the business I will use after speaking with them. Any disadvantage to this idea? I would like to know.
