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??
