Well Chuck, you got me researching the law myself. My God, you couldn't pay me enough to be a lawyer, anywhere! What a bunch of double talk and general gobbledygook. I looked through the regs and almost nowhere does it address muzzle loading pistols specifically. Now as cranky as the Canadians get over handguns, you'd think they'd want to be very specific about things in that regard. Anyhow, I tried, it's not a big deal so I'll drop it unless any of our Canaadian friends have a specific answer or can point me to a specific law regarding muzzle-loader black powder pistols, either antique or replicas.
