I have a customer's Tri Star shotgun in my shop. It has a broken trigger. The trigger appears to be made from a cast material and seems to be very brittle. I have tried every source that I know, to find a replacement trigger. I have even called Tri Star. No LUCK! The guy said he didn't have one and that he had other people who wanted them. He told me that the gun I was trying to repair was an older model. Several years old. (therefore buy a new model)?? Can't find parts anywhere User's recommendation: Buy a gun that makes spare parts!
