I don't know if you can buy a barrel for this handgun, but you can certainly have one made and the gun reclassified. If you can buy one, I think most gunsmiths can mount the barrel and reclassify the gun. If the gun's inexpensive enough, it might be worth having a barrel made for it. If you call Barry Jensen of Bits of Pieces in Delta, BC, he can advise you about this. He has put "restricted" barrels on a few different handguns for me, does terrific work and is very easy to talk to.
