Once upon a time in a magical place called Sig Academy the wicked instructor (Todd Rassa) held a force on force class. In this force on force class, the participants in the scenarios do not necessarily know how many rounds will be in their gun in order to set up malfunctions.
One bright and sunny day... Or actually, it could have been a rainy day, I was in this scenario, minding my own business, when I got attacked by a guy with a knife.
Well, needless to say I kinda took umbrage at the idea of getting stabbed so I drew my pistol and attempted to shoot the guy with the knife. Wouldn't you know it, somebody had only given me one round of ammunition.
With this fine gentleman with a great piece of cutlery in close proximity to myself and me with an empty gun I decided the better course of action would be to use the gun as a bludgeon instead of attempting to reload with the full magazine located in my left hand pocket.
I was throwing jabs with a sig 226 in my right hand and let me tell you, that is one of the best pairs of brass knuckles money can buy.
So that's my context for striking with the muzzle of a gun.
