It's interesting to me that the Duke began using a longer barreled Colt, and over the years eventually settled on the shorter barrel, the 4 3/4 inch model. It's handier, easier to carry, sufficiently accurate, better balanced in the hand, and easier to twirl. I think most single action enthusiasts would agree with that, but it's really a matter of what pleases you. I carry mine in a halfbreed holster, with a roughout suede cartridge belt, like the one that Duke used, and understand why he chose that combination. Also have nice El Paso rigs. But, a matter of choice. Whatever pleases your dad.My Dad came to me yesterday and decides he wants a brand spanking new "Colt 45". I was a little surprised but we discussed it and he has me on the hunt. Today, he asks me which barrel length I would buy if I were buying a new one and which one was the most desirable...and would likely be the most valuable in the long run. I can say that hes gonna fire it at least a few times so it won't be a Safe- Queen entirely. So....What say...ya'll? Which barrel length??
