(i) A firearm not designed or redesigned for using rimfire or conventional center fire ignition with fixed ammunition and manufactured in or before 1898, including a matchlock, flintlock, percussion cap, or similar type of ignition system or replica of such a firearm, whether actually manufactured before or after 1898.

...
-------------------------------------------
750.227 says carrying a pistol.
750.222 clearly defines a pistol and a firearm and it seems an antique firearm certainly fits that definition.
750.231 indicates the definition you are referencing refers to the the exeption which I read as the exemption for antique firearms only applies if it is unload and locked in your trunk.
I am not qualified to give legal advice, but the section you seem to be hung up on applies to 28.422, which is not the concealed pistol law as you claim.
