What is the best shotgun and ammo for home defense, IYO?
As for the best gun and ammo, it depends on the person and how the gun feels to them.
In my case, I have a Mossberg 500 12-ga. pump with 3 inch shell loaded with 6 shot turkey loads. (I live in an apartment). I also own a 1911(Rock Island) .45ACP which I can also use for self-defense.
For the record, I'm not a gun expert(I'm more involved in the political end of it as a freedom issue), nor claim to be one.
