Just picking from my own collection in case of emergency as a go pack:
M1 Garand, Remington 870 12Ga., Ruger .357 Mag, Colt 1911, DPMS AR-15 .308 w/4 x 12 Scope
It is better to have at least one proven Battle Rifle than Sporter’s only

Glock 26
Ruger 10/22
Mossberg 500
M1 Garand
AR-15 lower with multiple uppers (5.56, 6.8mm, .458 SOCOM)

Nobody said anything about limiting each gun to 1 barrel.
