These are the same requirements
for a concealed firearm permit that many right-to-carry states already have.
The difference is that the permit will be honored in all 50 states if you
have the aviation endorsement.

This has always kind of bothered me. I'm not a legal scholar by any definition
but it seems to me that just like our drivers and marriage licenses, auto
registrations, birth certificates, etc., our concealed carry permits should be
honored in other states per Article IV section 1. (full faith and credit)
