Arch,
I appreciate how much thought you've put into your set up. The combo of a hunting rifle and defensive handgun, and defensive rifle and hunting handgun between two people is a great mix. As far as the ammo, with the ability to carry so much 22LR I can see why it is the supreme survival round. I've been looking into picking up a Mark III, I think I would prefer one of the models with a bull barrel and the slightly longer(6.88 inch) barrel. Do you have any preferences with the Mark III?
