Do you need a pistol permit to get blackpowder revolvers or are they considered antique guns?
No permits needed for Black Powder unless you have some dictatorial state or other municipality.
Gun Control Act of 1968-'72.
Any weapon Pre 1898 that does not use fixed ammunition (metallic cartridges) or that proper ammunition is not readily available for the weapon is considered to not be a "FIREARM".
So black powder muzzle loaders of many type are not legally "FIREARMS". Cap and ball revolvers are indeed, muzzle loaders.
Loose ammunition i e powder, caps, and lead ball are not to be treated as fixed ammunition. Many in Law Enforcement and the Criminal Justice System are ignorant of the Gun Control Act. So be prepared to direct them to the clause of antique weapons and ammo. I learned this the hard way and even explaining to the authorities that BP weapons are not "FIREARMS" and not subject to confiscation when the FIREARMS box is checked on a complaint form, they didn't listen. I got everything back a couple days later but they still don't realise that my 4th Amendment Rights were trampled by them. Remember that if a court order is in effect about possessing FIREARMS that they will getbyou for violating a court order no matter how unconstitutional their actions are.
Another point. Pre 1898 includes 1873 Trapdoor Springfields and Rolling Blocks and a number of other weapons. These reproduction or original weapons can use fixed ammunition and there for do not come under the antique clause thingy. Old Colt Revolvers such as the 1873 SAA are FIREARMS. Just a reminder that Pre-1898 is not a blanket cover for all Pre-1898 weapons.
Anyway, I'm sure I have repeated what others have said. I really can't stress how important it is to have the Gun Control Act of 1968-'72 printed out or downloaded on your phone or computer so you can show them authorities the little ACT OF CONGRESS that they themselves should be familiar with. States don't outrank Congressional Acts.
Oh, and BP is an explosive not a propellant. You might want to check out your areas attitude about that also.
Cheers! I hope you find a weapon that you are satisfied with and I wish you safe and happy plunking in the future.
You're fine in New York. It's actually Federal law, any model firearms produced before 1898, including reproductions thereof, are in the eyes of the law are antiques and require no permits. Again with the exception of NJ and Illinois who don't recognize it.
