PC §46.01. Section 9 - Definition of Machine Gun - Still confused

[WildBill]

OK, I'm still confused on the definition of "machine gun" being defined as (my bold edit):
(9) “Machine gun” means any firearm that is capable of shooting more than two
shots automatically, without manual reloading, by a single function of the trigger

Why isn't this "...more than one shot..."?

I know the federal definition of a machine gun is “any weapon which shoots, is designed to shoot, or can be readily restored to shoot, automatically more than one shot, without manual reloading, by a single function of the trigger.”

Is there an example of a gun that should be allowed to shoot two shots with one pull of the trigger? Most O/U or double barrel shotguns I've used have either two triggers or a selector that allows you to choose which barrel to shoot first, but requires a second pull of the trigger to shoot the second barrel.

I tried to search the forums and found only this topic viewtopic.php?f=23&t=51840 but I didn't see a full explanation (apologies if there is a topic that covers this more in depth).

Thanks.

I always thought it was three or more shots.
