Looks like a lot of people besides me like the concept of the Mountain Gun. I currently own three. I first purchased a 25-13 in .45 Colt. Great gun, except it's blued (holster wear possible) and it has the ugly lock.
Then I found a stainless 625-9, also in .45 Colt. Now the holster wear problem is solved, but it still had the ugly lock.
Here's a shot of these two guns:
FINALLY, I found this one. It's a 625-6, with certain modifications to make it, in my opinion, ideal. I junked the plain black ramped sight for one with a red insert, obtained from Midway. Next, I got read of the "tear drop" cylinder release in favor of the old style. This is mostly aesthetic, but I think my thumb gets a better purchase with the old style. Then I got a pair of Ahrends Retro Targets. Couldn't ask for better with a holster gun. Pretty and practical. Finally, I had Nelson Ford do one of his primo action jobs on the gun so it's smooth as glass in double action fire. I think what I have here is ultimate trail gun:
