Remove the firing pin blocker, put on stock rubber grips, disassemble and polish trigger group and parts associated with it… when you are in there file the hammer hooks down just a tad over 1/3 and you will have a wonderful trigger, watch out, they are soft as tin.
If you have no idea how to do it, just dont, get one you trust to do it….i am a toolmaker so it was pretty easy done 😊
