This is probably a dumb question, but is there a readily available production hammerless smokeless muzzleloader available in either .40 or .45 cal?

Am emphasizing "hammerless" because I prefer every other option for a safety and not having to cock a hammer before shooting. Also don't like how hammer guns move back the trigger as they're being cocked (easy to get the tip of a glove caught between the back of the trigger and the trigger guard).
