The 629 Mountain Gun is my absolute favorite firearm. I've got one of the first edition, a 629-2 that was called the Mountain "Revolver" although it isn't marked that way at all. I've had it for a long time, since the early to mid 90's sometime. I think I paid $400 for it even then.
It's such a versatile gun in a very versatile caliber. I limit the 629-2 to mid range loads these days, a 240 grain Keith bullet at about 1000 fps.
I liked the first one so much that I bought a 629-5 Mountain Gun as a spare. It has the endurance package and can handle the heavy loads a bit better. I bought this one about 3 years ago, and gladly paid $600 for it used.
I put a Crimson Trace laser grip on it and took a wild hog with it a couple of years ago. My son used it last month to kill a 185# boar. It's quite a combination for hunting hogs up close.
I was at Cabela's yesterday, noticed that they have new 629 Mountain Guns, it's called the "Outfitter Series" or some such thing now. Price tag said $829.
