T/C pro hunter question

[doublelung]

This may be a stupid question buuuuuuuuut here goes:

Does each different caliber barrel for the prohunter have to be registered?

And if not what is the gun registered as?

One more:

Because its just a barrel, can one be bought in the states with no issues?

Thanks

no numbers on the T/C barrels ..the registration number is on the frame ..no the [usa] will not ship to canada [we are a foreign contry] but we fight the same wars side by side .. so much for FREE TRADE ..
