I have a JP in one of my lowers. I'm looking for another replacement for it. The issue has been since I got it that the disconnector MUST be a specific length for this work right. Mine is apparently not made right. After what seems like endless help from the JP folks, I give up. If I need a crisp trigger, then I end up with far too many doubles going off. Adjust it where it eliminates the unwanted second round going off and the trigger has miles of creep. I was looking at the single stage drop in units like a Timney but it seems that their quality is hit and miss. Some love them and some are as bad if not worse than what I have. Their 3lb trigger can go from 2lbs to the absurd 6lbs. I've been looking at a Jewell from GreatScottShooter. He's getting 205 bucks shipped for a small pin Jewell that's adjustable from 1-7 lbs. But I haven't bought anything just yet. But the JP has got to go.
