I really like my Gen 4 20. No FTF or FTE's at all. Great gun! The stock trigger is lighter that most stock Glocks I've handled, but no where near as light as my Gen 3 21SF with it's 3.5lb. connector. I've heard there is some new connector system they use in the Gen 4s. Does anyone know if the Gen 4s will take a 3.5lb. connector like the Gen 3s or how can I lighten the trigger up?
