Has anybody messed with the sear/striker interface? I may do some polishing there as well to see if I can make it bind less. Works great on M&P's, and I figure they took the concept from Glock anyway.
You should be aware that a so-called, '3.5#' connector actually produces a trigger pull at, or above, 4.5#'s. The standard coil spring should be installed in the shape of an, 'S' and not a, 'Z' when the trigger mechanism is viewed from the right-hand side with the trigger in your right-hand, and the THU in your left-hand.
Personally I've had the best results using Wolff Gunsprings throughout my Glocks. I use 6# striker AND trigger springs. 'Why'? Because trigger pull weight is not the only criterion by which to evaluate a Glock's trigger. RESET is, also, important; and the above components give me the cleanest, crispest break on the sear while firing from reset.
Make sure you polish your striker (FP) safety and firing pin well. As for myself? I strongly recommend that you do NOT use reduced weight springs in an EDC Glock. My own cumulative trigger pull weights average between 4.9 and 5.2#'s when measured from the center of the trigger's face; and, as I've said, the break is very clean.
LEAVE THE GLOCK TRIGGER BAR, 'KICK-PLATE' AND STRIKER LUG CONFIGURATION ALONE. Even a little bit of fooling around with it (polishing) can make your Glock highly unstable and prone to, 'ND'.
