if your shooting skeet at a range , you can only load two shells in a pump. If you walk up and put 3 shells in all your gonna do is scare people. All of the organized skeet ranges I've been to only allow two loaded shells , since only 2 clays are coming out at a station. The logic behind the 2 shell max is , if your shooting at two clays , you might forget that the 3rd shell is there and accidently injure yourself of som1 at the range. No reason to remove the plug.
