I've used scabbards from horseback back in the day. Love saddle guns, thus my Henry. Not sure that having it on the bike would be a good thing. But just think of the image of sliding the Henry out of a scabbard and slinging it over your shoulder after you get off the bike and head into some roadside facility. Cowboy Way.Wonder if they have some leather options, not a huge fan of Kydex.
@rapier57 I've seen some custom made ones for horseriding(you can probably hit your local leatherworker for one, probably would need some adjustments though)
