Let's leave those barrels on and assume there is 5-6 thou gap between the barrel hook and hinge pin to begin with. The barrels will be the sled. Repeat those strikes to the muzzles a number of times and the gap will grow...the gun will loosen due to "a force exactly like recoil without any pressure."
