Old Flattop .357:
Call me a weirdo, but this one strikes me as the coolest hunting gun in this thread.
That is my "Taffin" gun.
The short version is that gunwriter John Taffin very graciously donated both the grip frame and the barrel for the project.
After a gun show in Boise one day at the fairgrounds, he invited me to the house and instructed me in how to swap grip frames. All in all a great guy.
The gun started at a 6.5" barrel, but I prefer the present length better.
