I have a CVA Trapper and I have been having trouble with the trigger and hammer. I am having trouble keeping the hammer in the cocked position and in the half-cocked safety position. I took the trigger assembly apart and found that a small spring type device that puts pressure on the pin to slide it into one of the two hammer positions was broke. I guess it finally gave out through a lot of wear and tear. I'm not sure where I can find a replacement part. The hammer will not stay cocked at all now. I know I didn't explain this the greatest but hopefully someone can help me out and give me advice on how to solve my problem before turkey season! Thanks guys.
