Indeed

But I could also beat them to death with it

I've put a lot of thought into this. Considering I have the keys to a gun shop, I'd be packing these things:

MP5 or UMP: perfect close-quarters weapons with rapid fire rates. This is a last-resort weapon only, as they absolutely fucking fly through ammunition. I could drop 20 zombies in 30 seconds with one of these bad boys and they're both very portable.

An array of Glocks: Probably two or three, all 9mm if possible. Little kick, more rapid and accurate fire than a .45 and a 9mm is plenty enough to pop a zombie head.

Rifle: I'd take what was available and scoped and it'd have to be good for both long-distance zombie thwacking and hunting. So, pretty much any deer hunting rifle around.

Aluminum baseball bat: in melee situations, I don't need to kill because of my other armaments. I need to stun (and possibly kill) to quickly escape a bad situation. Baseball bats do not get dull, will never get stuck in anything (good luck with your machetes, boys), and carry an incredible amount of force behind a swing.

In short, when apocalypse time rolls around, I'm gonna outlive every last one of you motherfuckers.

my new best friend? lets kill those flesh eatting basterds

Sure, I could use some help carrying this:

Yes, we have one and yes, I've fired it.

I have the coolest job in the world.
