I think this topic is more suited to the General CHL Discussion section.....

I concur, carrying a fully automatic pistol is not what I would call wise.

However, as the law stands:

PC §46.05. PROHIBITED WEAPONS.
(a) A person commits an
offense if he intentionally or knowingly possesses, manufactures,
transports, repairs, or sells:
(1) an explosive weapon;
(2) a machine gun;
(3) a short-barrel firearm;
(4) a firearm silencer;
(5) a switchblade knife;
(6) knuckles;
(7) armor-piercing ammunition;
(8) a chemical dispensing device; or
(9) a zip gun.
(b) It is a defense to prosecution under this section that the actor's
conduct was incidental to the performance of official duty by the armed
forces or national guard, a governmental law enforcement agency, or a
correctional facility.
(c) It is a defense to prosecution under this section that the actor's
possession was pursuant to registration pursuant to the National Firearms
Act, as amended.
