About two years ago I got the bug for a 45 ACP revolver in the "Mountain Gun" configuration. Not for use in the mountains but for walks in the desert where I live. My concern was more the two legged varmints or the four legged variety infected by rabies, which we see occasionally in my State.
Anyway, my affinity is generally for carbon steel and after a little research I found out Smith & Wesson never made a Mountain Gun in blued steel. While mulling this over I saw an add here on the Forum for a M25-2 that had an old Model 1950 tapered barrel installed. I bought it and shipped it to my gunsmith. He cut the barrel down to 4", Pinned the ramp to the barrel rib then the front sight to the ramp (the way S&W used to do it), then round butted the frame. A trigger job was naturally included along with making sure the indexing and timing was perfect. Finally, after a light bevel on the forward edge of the cylinder, he fine bead blasted and blued the whole thing. I've posted the pictures enough times that I'll skip that step for fear of being accused of bragging.
The point of my tale is that one way to get what you want is to have it built. Is it worth the money? That's very much up to the individual, but I will say this 45 ACP, blued Mountain Gun look-a-like is one of my very favorite revolvers.
