I’ve been wanting another revolver for my very small BP collection. I’ve decide to go right to the top and get a walker colt. The first time I ever heard of this gun when way back when I saw the movie Unforgiven for the first time and they mention someone using one and it blowing up in there hand. I did a lot of reading about them yesterday and they have such a great history. I do have a few questions of you guys feel like educating me. The colt walker came out before the colt Dragoon??? What are the differences between these two guns? why did so many of them blow up ?
