What I had before that tragic boating accident where all my firearms ended up at the bottom of Lake Michigan.
Easiest is probably in order of acquisition:
Savage pump .22LR
Remington Viper .22LR
Chinese SKS 7.62x39/"Russian Short"
Ruger P90 .45ACP
Cobray M12 .380
Ruger Super Redhawk 7.5"bbl .44Mag
Feather Industries RAV-9 9mm (used to be an AT-9, but was brought to current rev. by the mfr.)
Maadi MAK-90 (AK-47 clone) 7.62x39
Kimber Tactical Ultra2 .45acp
Taurus Millenium Pro PT138 .380 (it's pink! for the wife)
Davey Crickett single shot bolt action .22 (also pink, for the kids)
Rock River Arms Tactical Entry AR-15 .223/5.56
Sig Sauer Mosquito .22LR
Luger P-08 9mm (WW2 trophy, Mauser "41" marking, all matching numbers)
Remington 870 Tactical 12g
Ruger LCR .357 .357mag/.38
Ruger LC9 9mm
and "in my care"
Winchester 1894 30-30
Mauser P-38 9mm (WW2 trophy)
Walther PP .32 (WW2 trophy, from the Allied forces liberation of the Walther factory April 1945)
Walther Modell 2 .22lr (same as above)
I think that's all of them for now... Bring on the zombies!
