I am trying to decide on a 12 ga or 20 ga double barrel shotgun I used to have a SXS CZ 12 ga never shot it traded it to my brother he won't sell it back i see a 20ga for sale on here It would be used for home defiance and maybe a little hunting, I know a pump or auto would work but I am 73 now I have some 12 ga ammo guess i could trade it if i go the 20 ga.
