I am looking for you recommendations on a trigger upgrade fro my G19. I had a Ghost ultimate 3.5 drop in connector in my previous Glock (gen 3) and loved it and so i got one for my new Gen 4 G19 but once i put it in it doesn't work. It doesn't activate the firing pin so when you pull the trigger you only hear the click of the plastic moving but no firing pin dropping. and not only that it causes the trigger assembly to bind up with the slide so its a PITA to get it back apart. i took it to 2 different Glock Armorers to see if maybe i was doing something wrong but they all had the same results when they installed it. So what Connector do you guys use?or recommend that I use that is a drop in?
