do you not need the lighter striker with that shorter striker spring installed?I have experience with both the Ghost 3.5# connectors as well as the Zev Fulcrum drop in kit. While polishing and a few spring replacements along with the connecter can make for a much better trigger, I still feel that the Zev Fulcrum drop in kit is superior (in my opinion, having shot both). Part of that is from my preference for Zev's flat faced Al trigger...much better feel on my finger than the stepped/serrated trigger that comes stock on a G19. I run the Fulcrum drop in kit with the stock plunger/spring and striker/spring and have had no issues with it whatsoever. Takes away a good bit of the take up, eliminates overtravel, crisp break, and the stock springs leave in a little added resistance/"mush" to the initial trigger pull... Using Zev's or Lightning Strike's plunger/spring and a lighter striker spring from Zev, the trigger is oh so sweet, but not as carry friendly, for my personal use in my opinion (others may prefer it and be fine with it, YMMV).
