Trigger broke on USP, options?
 

I have a old Tanaka USP that the trigger broke on, I would love to put a Real USP trigger(it supposedly is a direct fit) in it but cannot locate one to purchase in Canada. If I have other options I would love to hear them. I don't think I want to put another pot metal Tanaka in there, and I doubt I could even find one. Any help is appreciated.
