I am not completely familiar with all the ccw laws in Kentucky(I should know since I live here) but I know black powder is not legally a firearm, so you may be able to carry one without a permit, not sure since I never looked into the idea of carrying BP but if I did it would be this.
I wish they made one in 12 gauge, but I can assure you a bad guy will **** a brick if you whip out one of those.
There is one with a stock in the rifle section,a stock you can buy separately, and a holster. If there were half that price I would get one right, but right now a bit high for BP for me.
by federal law a BP is not a firearm, you can buy one and have it shipped to you house, no ffl needed. The question is what does the state consider a weapon for the purpose of needing a ccw.
