Timney uses sear with reduced engagement notch to get crisp pull. It is not so crisp as set screw for engagement needs to be adjusted a bit more finely. But they must have used LocTite 271 Red on it as I had to use soldering iron on screw head to break the bond. .THEN was able to get 9crisp break. BUT now you have t p readjust and stone the safety. Now you have a one of a kind gun. Easier to judge to be oem seat too to get crisp pull, cost nothing. I have 3 of these guns and have done a dozen more, ALL with tuned I am parts.
Same parts work on a Ruger 77/357. Clean crisp, 3 pound break, no mush or creep.
