Based on some positive reviews I installed a CGW supplied extended firing pin and reduced power FP spring. Took it to the range to practice and I had several FTF, i'm uncertain if that was related to the random (but factory TSO) recoil spring I had in. I replaced the stock FP and FP spring and replaced the recoil spring with a CGW 13lb and the problem went away. Also important to note that my firing pin block/retainer nearly fell out, the firing pin was way to the front.
Factory FP stuff and the 13lb recoil had zero issues during my last match. I just swapped the stock hammer spring for an 11.5, keeping the 13lb recoil and i replaced the FP with the extended FP but did not swap the FP spring. I'm going to see if this works and since I have a much lighter main spring I may revisit the reduced power firing pin spring.
Has anyone else ran into those issues? I'm just trying to learn a bit tweaking things a little at a time to get a light trigger and a flat shooting gun. Next on my list is replacing the trigger, I have the floating pin and a choice of a couple triggers to try.
