First I am on a budget for prepping and guns. I think I think I need to get a handgun first. My question is. I have a 16 gauge double barrel shotgun I inherited from my father when he passed away a couple years ago. I have very little ammo for it was wondering if I should build up a stockpile of ammo or just get a smaller amount and eventually get a 12 gauge to replace it. If I decide to replace it it maybe a year or more before that can happen.
