Safety needn't be an issue. Probably designed so it can't fire with bolt open. Can't fire with safety on. Can't fire until x - lbs. of trigger pull etc...
Just another attempt to reduce one of the "hassles" of MZ, occasional no or slow ignition. I kind of look at the "ignitionally challenged" aspect of muzzleloading as one of its desireable aspects. The one that gets away was meant to get away.

I actually sent that link to our DNR when this came up months ago, wondering if it would be legal on MD. No reply. Guessing they don't know for sure.
Precisely what I was thinking when I started this. You got to love those hang fires and the ones that dont always go off.
