I like HatchetMan's style,but i would probably grab my baseball bat and my knives and if i could i would get a .22 rifle or handgun...silent,lightweight,easily obtainable ammunition,and can bring down small game.Hell I'd grab my Dads 9mm or .44 revolver.
I'm designing a revolver for a post-apocalyptic world I can't say to much about it right now but I can say that when it's made it will be my pride and joy. I call her The Wild Boar.
I'd want a Taurus Judge because it shoots 410 shotgun shells and .45 rounds.It can hold any combination of 410 shotgun shells and .45 rounds up to the maximum of the 5 chambers.But the 410 is extremely weak,though.
revolvers do jam, the ammo can slide forward and keep the cylinder from turning and primers can fall out the back causing a round to not fire. there are more ways a revolver can go from gun to chunk of metal.
no problem just disspelling the "revolvers never fail" thing. because as with any gun you will run into malfuntions it's just a unavodible fact that everything will break even the all mighty AK.
