Steve, can you legally send a firearm to the US for repair? I don't know import/export law between the US and CA. Anyway, if you can, Mike Bellm is the man who can make a TC Contender run like a champ. He also sells kits that you can do your own trigger job, should you be inclined. He's a bit eccentric but really knows his stuff.
