Can’t do a 12ga. I’ve shot my dad’s M1 and loved it but was just wondering on comparisons.
I wouldn’t recommend any rifle for home defense.
I would rule out .223 due to over penetration.
I think the M1 carbine is a very useful close quarters gun. I like 12 gauge. Still, that 44 mag sounds like a show stopper.
I just worry about over penetration, in a close quarters environment.
