It seems that when trigger assembly is working the sear, the firing pin spring and the recoil spring are being compressed for about 1/8" to 1/4" and slide moves that much. Then the movement stops and with more rearward movement of the trigger, the sear releases. It seems like there is something that allows the slide to move with the trigger bar assembly. My concern is that with slide movement like that, the chamber is quick to release and the round will not be hit as hard as normal. Or possible reduced support for the round being fired. I tried the pencil test (#2 Pencil place down barrel eraser first) and the resulting movement of the pencil was about 1" - 1 1/2". Suggestions? Try a new trigger bar assembly?
