I have a very interesting problem that I resolved by fitting a new sear, but I’m not sure if this was the appropriate action, and would like some insight, how does one increase the sear lift on a Stock 2, if this is even possible?
I bought this Stock 2 used, and it has the following relevant components:
Xtreme Titan Hammer
Xtreme 1-wing Interruptor
Stock Trigger Bar
Stock Sear Cage
14# Wolf Hammer Spring
I had hammer follow, and I quickly determined that it was a worn out/busted sear spring. A brand new sear spring looks somewhat flat with a almost 180 degrees with the two legs, but on my busted sear spring the short leg that goes in the sear pocket was bent 90 degrees and now the sear spring looked more like a L.
I proceeded to replace the sear spring with a Tanfoglio Stock sear spring, but now I find that the sear is dragging on the hammer. The hammer drops in both Single and Double Action, but the sear is lifting high enough to drop the hammer but dragging over the hammer hooks where you can feel it. I checked the trigger over travel screw and completely took it off, but it was still dragging.
I checked the trigger plunger spring and it’s moving fine, everything was resetting properly too for DA/SA, and the trigger bar looked okay, too but the dragging remains.
I ended up fitting a brand new one-piece sear (non Xtreme, fitted just the safety leg) which is now lifting high enough to clear the hammer, but I also find that I don’t need the over travel screw at all now. I arrived at the conclusion to replace the sear, because the sear looks to be potentially the older sear that were tempered incorrectly or not enough, and it looked fairly polished but I could see slight deformation/indentations on the sear edge where it engages on the hammer hooks.
