Easy answer is just shoot 410's in that, get a 44 barrel for 44's.
Right as usual S4S4U! And if you do a poll, that is what most of us do. I brought up 410 slugs just incase you really need to shoot a single projectile.
...to be a legal pistol it had to be rifled and be able to fire a pistol cartridge...
You are right, that is the only way they can put a shot gun in a short barrel. It is still the reason they make the 45/410 today. Generally 45's don't even shoot out of the 410 very well.
