    Nope all my Gen 4 pistols have Gen 3 Glock 17/22 trigger bars.

    What is the purpose of the bump on the trigger bar on the gen 4 guns ?

    It keeps the plunger safety tab centered on the plunger safety by removing some of the flex in the trigger bar.

    Same as Robb. I put gen 3 17 trigger bars on my 19's (smooth trigger as well).

    Same here. My gen4 wears a gen3 connector. No issues at all.

    Does the Gen 3 trigger bar (without the bump) actually do anything for the trigger pull weight? Is it that noticeable? (I've heard both ways, that's why I'm asking)

    I've also heard that Glock is going with Gen3 trigger bars WITH the bump now. True or False? If true, are the "non-bump" bars going away?

    Yes the without the bump Gen3 trigger bar will lower the pull weight my 1/2-1lb if used in a Gen4.

    Gen3s are still coming with Gen3 trigger bars.

    Thanks for the reply Robb.

    I was looking at picking up this one since I was getting some Defoor sights from LWD anyway...Good to go? (I don't mind the serrated tigger btw)

    Yes that'll work fine. I use Defoor sights on my G35Gen4 for shooting competition.
