RE: new slug gun
A slug gun? Can you use rifle and just want to try a slug? If so id stick to a rifle, however if youre a slug only state, I think benelli 20ga.....would be awesome. think its the m1 or something.
12ga? maybe a rem 1100, or benelli would be the 2 id consider.
24" rifled barrel. though I read somewhere that slug barrels only need to be 21"
