thanks,
Matt

Matt, yes you have to adjust them all. I personally don't use them. I like the Nowlin 3 leg better but I have put them into a few pistols on request. George

The four prong spring was designed for a special mainspring housing that was drilled and tapped for a small set screw. adjusting the screw would allow about a pound of user adjustable trigger weight change. Jim Clark is the only one who used the system.
