Actually that is not a shotgun ... it is classified as a handgun. Never mind that it fires .410 shotgun rounds. It's like Thompson-Center making handguns that fire rifle rounds.
Nice gun though. We never could keep one in the gun store for more than a week .... and for a long time they were hard to get from our suppliers. I spent 2 months trying to get one for a customer ... couldn't get one before I had to close down the store and sell off the inventory to another gun store after the owner died.
America! It's about
Nope, it’s a pistol chambered in .45 Long Colt. It has a rifled barrel, a rotating cylinder, it’s design was intended for the gun to be fired from the hand.
By design, .410 shot shells may be fired through this pistol, hence the length of the cylinder to handle the longer shell length of the .410.
Inversely, I wouldn’t suggest you start firing .45 Colts through your .410 shotgun.
