This is a pretty cool 410 pistol. It's a Thompson Center Arms 45 Colt. It has a rifled barrel and a removable choke for shooting 410 shotgun shells. I've never shot 45 Colt in it. I don't shoot it much. The last time was a few weeks ago when I shot one of my Drones out of the high tree it crashed into. Shot the branch without getting one pellet in the Drone. I also have the scoped .223 barrel for it. Cool plinking gun.
