Scuf replacement part - Adjustable hair trigger

I own a Scuf 4PS pro with one adjustable hair trigger. A part of the trigger is broken and I really need/want a new one. I contacted Scuf and they don’t send replacement parts or fix specific parts (they would need to fix all the problems). I have been trying to find somewhere to buy only 1 Adjustable Hair Trigger for a reasonable price and I can’t find one anywhere. Please help!
