If I could have only one gun it would have to be my Ruger mark 2 government target model .22! With this I wouldn't starve to death and could also do a fair job of defending my family. But since we are just doing what iff,s I'll keep my 30-06, .270,.308 tactial,45-70 marlin,.223 varmint couple of SKS,s MAC90 two glocks two Kel Tec,s Super Blackhawk and some other stuff cause I'm a gun nut!
