Went shooting with my new G19 gen 3 yesterday. It went great except the trigger was bugging me. I kept flinching from recoil and the heavy trigger pull (my issues, not the gun) Went online and looked up how and what to polish to lighten/smooth the trigger. Found this and it was a huge help: View: https://www.youtube.com/watch?v=0XJxltxvAo4 I used his approach of polishing using qtips and polishing compound. Then I cleaned and lubed it. It made a *huge* difference. Can't wait to try shooting again.
