... I'd like a gun that fires a huge nail that penetrates your opponent and then loops back and catches fire before ramming your opponenet. Then the nail stop abruptly infront of him where it lands on his toes and explodes. That's a gun.

Otherwise I'd like to see a rocket launcher that fires rocks that explode into nails to sail through your opponents face where it ejects a good dose of poisin and some of that stuff dentists use to drill holes in your teeth without having you feel it. Thereafter the nails explodes which blows off your target's face. Now you got their face blown off and mangled, and even if they survived there loaded with poisin and the numby thing.
