I specified the "Antiques" section which the definition clearly applies to muzzle loading pistols & C&B revolvers.
This thread involves shipping C&B revolvers which the rules below apply to.
If you can post something else that's currently in the USPS regulations that states otherwise, then I will be all ears.
"Antiques:
Antique firearms are defined as any muzzleloading rifle/shotgun/pistol, which is designed to use black powder or a black powder substitute, and which cannot use fixed ammunition.
They must be:
- Mailed between curio and relic collectors only when those firearms also meet the definition of an antique firearm.
- Certified by the curator of a municipal, state, or federal museum that exhibits firearms to be curios or relics of museum interest."

Curious why you quote a ‘regulation’ interpretation from a third party, ShippingEasy Support Center, instead of going to the USPS website? Below is directly from the USPS,
Policies, Procedures, and Forms Updates, and is their definition of a firearm (12.1.1a). Notice what is not included in the definition of the term firearm, which I have highlighted. The
term shall not include an antique firearm. Below that is the USPS definition of the term antique firearm (12.1.1h), basically what I have been understanding for years. Antique firearm means any muzzle loading rifle/shotgun/pistol that is designed to use black powder or a black powder substitute and that cannot use fixed ammunition..... manufactured on or before 1898, or any replica thereof, if such replica is not designed or redesigned for using rimfire or conventional centerfire fixed ammunition.
The last cap and ball pistol I ‘mailed’ was sent out in June of this year. Bride took it to the USPS, mailed it and it was confirmed delivered a few days latter. I asked her last night if she remembered what questions they asked or what she told them. She forgot exactly what they asked, ‘maybe something about anything dangerous’, but she used the cheat sheet I gave her, and she told them it was an unloaded replica of antique cap and ball pistol. They didn’t bat an eye as they took the USPS Flat Rate box and the money.
