I'm not much of a handgun guy, but I got a T/C Contender with the .45 Colt/ .410 barrel on it. I really like shooting it and will use it primarily in the .410 for Grouse next fall.
However, I'm wondering what would happen if I shoot a .45 magnum round through this gun? It is made for the .45 Colt, and the bore although rifled, is smooth all the way.
