Leave the 12ga for us young bucks
The 20ga is my house gun. I had a 12ga 870 for the house, but my wife wasn't great with it past one shot. She can shoot the 20 without any problem, but it's difficult to accessorize. I don't have the 12 anymore because my safe isn't big enough to keep 'em all.
As stated above, I have the Stoeger 12ga SA for all my hunting shotgun needs. It'll run any round between 2 3/4" and 3 1/2" reliably. It's black, I might do a rattle can job on it.
