Right now, between my wife and I we own around a dozen guns. Some fill our defensive purposes, some could be used to put food in the freezer if the grocery store ran out, and some could fill either role if need by. Right now, our basic firearm needs are met but that doesn't mean we're done acquiring guns. I want an identical Sig Pro to compliment my carry gun as a dry fire/training gun.
I also have a few sentimental guns that my dad gave me.
