You need to expand more.

you need a shotgun, a carry gun and a home defense gun ( I guess these could be the same...but why!!)

at a minimum, you need 3 guns.

handgun, carbine and shotgun.

get a nice .45, find something you like. 1911 would be a great choice, but others will say glock, others will say XD45

shotgun, a nice 12 gauge. most guns eat anything, just get something that shoots 2 3/4 and 3" shells. can't go wrong with a tactical 870

rifle, get an AR. nothing evil about them. People swear by Colts, others by Noveske, others by LMT. pick and choose. they all work great.
Have at least 5-10 mags at a minimum. 500 rounds of ammo would be the very minimum.

this is the bare minimum in my opinion.
