I put this in my rail. For home defense you don’t need a site. Green Laser Sight System by Ozark Armament - 5mw 532nm High Powered Tactical Green Laser with Picatinny Rail Mount Barrel Mount Pressure Switch and On/Off Switch for Rifles and Shotguns. Very bright, don’t use the extended on off switch, too complicated, cruiser ready, two buttons and you are ready to go.
