Oh yeah, I've looked into those: the prices are insane. What is it, $90 for the hammer alone?
I was thinking about the viability of a JP Trigger-ish setup and putting some set screws on the stops for the trigger (fore/aft) and disconnector, instead of using shims, but the cost of a likely screw up is astronomical. And since I no longer have access to a mill, I'd have to farm out that part of the screw-up, too.
Wonder if Bill Springfield or Bruce Gray would be interested...probably no less expensive.
