My buddy has an M1 field and I don't no who showed him how to do it (because he's to stupid to figure out anything like that on his own), but he does it once in a while and thinks it's cute. I think it's stupid. If you want an extra shot then just stick your plug in your pocket and load up all five. Better yet, just eat your plug and thread on an extended magazine. Load up some nickel-plated lead and just punchout wide open. Seriously three shots are plenty if you make them count.
