I'm in the market for a rifle to add to my measly arsenal of 1 gun (glock 9x 19 pistol). I'm buying primarily for home defense, but will also enjoy using it at the range. I'm seeking input on which weapon to buy, as I know virtually nothing about them. I'm considering buying at one of the many pawn shops in my area as I'd probably get more for my money that way. Anything to look out for when buying "used"? I like shooting my father in law's 22 magnum, but I don't know if that would have much stopping power. I'm not really looking for a shotgun right now.
