Hollywood just needs to make a movie about some super kung fu MMA trained 19th Century Cool Guy kicking serious ass and piling up mounds of bodies using a prominently featured M&H. That would jump start demand and the increasingly bad sequels would keep it going long enough to sell a fair volume. Kind of like what "Jeremiah Johnson" did for Hawken rifles or "Dirty Harry" did for .44 Magnum Smiths.

Gunnery, gunnery, gunnery.
Hit the target, all else is twaddle!
