This country has plenty of firearms. But I would guess that 95% of their owners have no more than a 50 round box or two of ammo for each of them, and they consider that plenty.
So, if you already have a rifle, a shotgun and a sidearm -- and are COMPETENT with each -- don't spend all your money on an upgrade rifle, spend it on ammunition. If you are not competent with them all, spend the money on training. Training, local organization and logistics are the hard elements of preparedness. Guns are easy.
