I bought a police trade in Gen 3 several years ago.I experimented with several combos including an Overwatch Poly Dat trigger (which IMO sucked) and ended up with a 3.5 connector and 6 lb trigger spring being the best for me.Glock triggers seem to be a matter of personal preference more than any other pistol ,you just have to put in the work to see which setup you like.
