Some sort of high power bolt action hunting rifle.
I think this would work 270 Sako Finnbear
A 1911 in .45 cal with an ACE 22 cal conversion.
Gold Cup 45 the second is with an Ace 22 coversion
Pump action 12 gauge.
My choice is an 870 with two barrels. One short for home protection one full choke long barrel for hunting
Some sort of assault rifle for Zombie deterrence (government or alien)
Mine is a HK SL8 in 5.56
I guess that leaves something to carry;
I go old school for this Colt 1908 .380. It gives me that Al Capone feel.
