I've got the 41Mag Mountain Gun back before the lock was added to Smiths. Nice gun, but, as another here commented, I'm not sure it has much advantage over a regular 657. Officially, as I recall, Smith claimed about a 3 ounce difference.

Funny no one has mentioned the Mountain Gun in 357??

My g8-g8 uncle was Barney Riggs. Google and read about him. He roamed around the southwest, mainly west Tx and Az and NM territory. History credits him with from 9 - 12 men he killed, not counting Mexicans and Indians. Family lore has it at 18.
