I'll take my trusty .45, failing that a full suit of chainmail with good leather boots, and a full faced helm+chin strap. Who cares if you're surrounded by 1,000 zombies, they aren't likely to bite through chainmail. Hell my dog couldn't even chew through my leather combat boots. (Boy did he try.) I'd like to see the rotting jaw muscles of a re-animated corpse bite through steel rings.
Sure I'll get tired eventually, but all I need to do is find a stairwell/corner and start hacking until I've made myself a nice little wall of dead zombies.
