Not to continue to derail the wonderful tacos....:D
but I had a Riffe trigger mech fail on an almost new gun. I was swimming back to my boat and just touched the trigger and THWAP !! It fired. Surprised the shit out of me. So I loaded it and did it again. Then I took it home, went out in my back yard and held the gun parallel on the ground with a free shaft. It still had a "hair trigger". Jay Riffe sent me a new mech free of charge, and it never had problems until now. I'd heard it happened to a couple others also.
Now....about that taco recipe.....
