Muzzle brakes are not without drawbacks. They can take a gun that is not unpleasant to shoot with ear plugs and make it deafening with them. Shoot the dang thing without ear plugs and the ringing may be with you forever and ever and ever. Not to mention the increased flash and powder coming your way.....hardly desirable characteristics for a defensive shotgun. I weigh 160lb soaking wet and do not find the recoil of the KSG unpleasant or unmanageable. Me I'd rather take it a bit harder on the shoulder than hit my ears with any more pressure than necessary. Bruises heal, hearing loss is forever.
