Forneyrider,
I was also interested in the JP trigger for my Panther Bull. I bought mine from an LEO who has an FFL and side business and he ntold me I would be MUCH better off with the Timney trigger.
I am glad I listened to him. He said, and I agree, the Timney is better than the JP.
I have shot some DPMS with the JP trigger and I have to agree.FWIW.
