The "Zombie Survival Guide" that Alko mentioned highly recommend a M1 Carbine. Mainly because it's compact, durable, and can be used as a melee weapon assuming you have a wood stock or bayonet lug.
My brother had a pretty good idea for weapons. (Well kind of good) He said he'd use a MP5 and a Glock 17, which is not a bad idea since he'd only need to carry one type of ammo. The only problem with that idea is the MP5.
I still think he had a good idea with only need to carry one type of ammo. So I thought about using something like a Beretta Storm or HK USC and carry a 1911 as a sidearm. And of course must have shotgun!
Maybe that Remington 11-87 I had my eye on.
