Jewell $210
Trigger tech $125
Timney 510 $110
Neil Jones tuneup of factory trigger $75
I've used timney, jewell & Neil jones. All three are good with the jewell being the best. I've heard good things about the trigger tech but haven't used one.
^^^^^... Unless I am mistaken the factory trigger shoe has broken in the past since it is a mim part with a hole thru it for the adjustment screw
