Section 232.1(1) bans the storage or possession of weapons (concealed or otherwise) in an
enclosed postal parking lot, whereas 18 U.S.C. § 930(a) bans simple possession of a firearm in a
federal facility/building provided the requisite notice is posted as described in § 930(h).



Enclosed parking lot, meaning inside of the gates, past the sign with the legal language on it.

I don't go inside that part, I merely use the parking lot that's open to the public.

Start at the bottom of page 11 of your above link.

It should also be noted that the above mentioned case was a Postal Employee who had ammunition inside of the Post Office building itself and a load concealed handgun inside of his vehicle while it was parked inside the gated portion of the parking lot.
