I think 45 colts are great guns, I have several a 4" 25-5 would be a nice carry 45 colt. A pre "mountain gun"LOL. Only possible draw back is some of the early 2505 had big thoated cylinders. Some get results from them others can't seem to. Don't think there were that many 4"25-5, The price might be a bit of a put off. Not saying it isn't worth it.Just other big bore choices for the money and the actual number of 45 colt fans compared to 44mag fans is small, Maybe around the number of 41mag fans.
