Mountain guns are my favorite S&W, and it looks like I'm in good company.
When the 629-2 "Mountain Revolver" first came out I bought one, even though I had three other S&W .44's aat the time. It didn't take long for me to trade off the other guns!
I ended up with two "Mountain Revolvers" and a "Mountain Lion". The 2nd 629-2 never shot as well and the "Mountain Lion" was to pretty for me, so they both left.
The original 629-2 has had at least 15,000 rounds put thru it. That gun could tell some tales, it's been carried as bear protection in Alaska, shot squirrels, grouse, deer and elk, it even shot the top out of a tree that was hung up in a power line this last winter! It's been my "go to" gun for nearly 20 years. Just lately I noticed that the trigger pivot pin had come loose, so it's gonna have to go back to S&W.
Well, I have all these holsters for a MG, so I bought a 625-6 .45 ACP to keep me company. What a great shooter. I was sighting it in out back the other day, I fired 3 shots offhand at 50yds to check my sights. When I walked out to check I had a 1-1/2" group!
Now I'm thinkin' I need a .45 Colt.
I guess you could say I'm a fan!
