I've got one of the original run of mountain guns. Chamfered cylinder, bead blasted stainless finish. I had Andy Cannon work over the action nearly 20 years ago. It's a slick accurate little sixgun. I usually carry it in a crossdraw full flap thumbreak holster.
It's been the revolver that I use as a yardstick to measure all others.
I've probably put 15,000 rounds thru it. Mostly 240-250grSWC's over 8.5gr. Unique. For a full house load I like a BTB 280gr WFNGC over 21.5gr WW296. There isn't enough sight adjustment for any of the heavier bullets.
I was working in Southeast Alaska about 15 years ago and carrying the MG every day. I climbed up on a huge Sitka Spruce blowdown to see over the brush, I was about 20' off the ground. A really nice Sitka Blacktail buck was bedded in an inaccessable spot right under the tree! I just leaned out and shot him between the shoulder blades!
