Alright so I'm looking for THE CHEAPEST home defense pump shotgun. Every time I go looking for one they're always 20 GA. I'm looking for a 12 GA. Anybody have any specific gun suggestions? It doesn't have to look good, or have cool additions. I just need one that functions. i'm specificalyl trying to keep it under $300 as I'm short on cash. All suggestions are welcome, and thank you in advance!
