Did you know?  
You can mail pistols and rifles at the USPS?  Restrictions to apply, but they do
mail firearms.

There is much debate over whether it is legal to carry or not on USPS property.
It really is up to the management of that branch.
Signs are to be clearly posted of what is prohibited and enforcement is
suppose to be the job of the USPS.

I have found no evidence of anyone ever being charged with a crime or
violation of a regulation for carrying a concealed firearm with a CCW license on
USPS property. A conviction of such violation I believe would be nearly
impossible considering how the regulations are written.  Is a regulation the
same as a law? A law doesn't need to be posted, these regulation require
being posted for warning.  Enforcement is up to the individual branch on what
they consider to be safe. The truth is until someone with a CCW is arrested for
simply carrying we will never really have a verdict on this discussion.

Bottom Line For Me.
I carry concealed. Concealed means out of sight.  License CCW holders are
typically the most responsible law abiding citizens on the planet.  If a CCW
license holder is arrested for carrying, it's probably due to them being
irresponsible or just plain stupid.
