thanks sixbears....

i'm probably not using the right terminology. the parts that broke is a 1/4 inch piece with a hole in it about and inch long and 1/2 inch wide that moves back and forth to disengage the action when you move the thumb lever oraction lever. clearly I can see that it was already stressed with very little actually holding it together. when I took it pidgeon blasting yesterday ........it let go after a box and 1/2 of number 6.
