Many years ago I showed up at the guides house long before daylight at the assigned departure time for a cougar hunt in Colorado. The guide loaded the dogs in the pen on the back of the truck and asked me if I was ready. The next question was. . "Where is your gun?" I unzipped my coat to expose my pet Python only to be met with a scowl and a "You plan to hunt lion with that?" When I answered in the affirmative the guide went back in the house and retrieved an M1 Carbine. Oh such little confidence.
Interesting. I went on a Mountain Lion hunt in Arizona in 2011. I asked the guide if I could use my revolver. He said he prefers it! This was a dry ground lion hunt on horseback. I showed up for the five day hunt with my .44 special. The guide had his old beat up Ruger Single Action with him........... .22LR, I asked him about it and he said it don't take much to kill a lion. We quickly became good friends
needless to say, I am going back to hunt with him again. This March.
