Autographed Muh Keen Gun
Not content to kill things one bullet at a time, Sniper commissioned the best gunsmith in the land to construct him a firearm worthy of his talented trigger finger. Lovingly designed and crafted with all the skill and attention to detail befitting a master smithy of the keen, the weapon that resulted is truly one for the ages. It's a bit on the heavy side, true, but not when balanced against the weight of corpses it will produce. Hernia not included.
