Ruger Alaskan in 454. Will shoot 45 colt. Like a 38 spl. In a 357. It is a BIG snub nose . Used s&w model 25's. they go for a premium. I too would love a 45 colt double action. I sometimes carry my SAA Cimarron with a empty chamber under the hammer. I really like the diversity of the 45 colt round.
Strive to live up to the opinion that your dog has of you.
