I have the same revolver and often Carry it while hunting deer and elk, BUT, it is in no way legal to use it to shoot either animal during the ML season in CO. nor is it legal to use it to administer the "coup de Grace", since ALL firearms used during ML season must comply with the definitions set out in the regs. Neither does it meet requirements during modern season since they are based on energy requirements that no existing c&b revolver can meet.
You might wonder why I'm packing a revolver that is not" legal"? Well, it is perfectly legal to use for any small game season that is concurrent with the ML season.
It gets even more peculiar though. It is legal to carry any weapon while hunting ML season as long as you don't use it to kill or attempt to kill your big game animal. Legally, I could carry my ML in one hand and a .375 H&H in the other, as long as I don't use it to shoot the big game animal that is in season!
Here is another CO odd one. Hunters are exempt from the Prohibition against carrying a concealed handgun even if they don't have a CCW permit. So, if your clothing covers it or its in your pack, it is OK.
A law abiding friend of mine got a citation a couple years ago when he used a hand gun to finish a big game animal. He shot it in the Head. The animal and the hunt area had mandatory CWD testing and the biologist discovered the way less than .50 caliber hole in the skull. He ended up paying a fine.
Reading here about the various regs regarding hunting and firearms use is certainly a reminder that we live in a sometimes non-sensical world
