C.R.S. 18-12-401, definition of a firearm

[O2HeN2]

C.R.S. 18-12-401 has the following for the definition of a firearm:

(1)(a) "Firearms" means a pistol, revolver, or other weapon of any description, loaded or unloaded, from which any shot, bullet, or other missile can be discharged, the length of the barrel of which, not including any revolving, detachable, or magazine breech, does not exceed twelve inches.

So my reading of this run-on sentence* tells me two things:

1. Anything with a barrel greater than twelve inches is not a firearm by Colorado law.
2. Suppressors are not firearms since they cannot discharge a bullet.

Could a lawyer out there tell me how Colorado sweeps rifles and shotguns into the definition of "firearm" given that they have barrels longer than twelve inches?
