Replacing Glock 19 Gen4 trigger with Glock 17 (Gen3?) trigger

[bacon_lover]

After shooting 500-600 rounds through my new Glock 19 Gen4, I can safely say that I hate the tactile feel of the trigger. I ordered a smooth G17 trigger with the intent of swapping it out. However, I believe the trigger + trigger bar I have may be a Gen3. Will this still work in my G19 or do I need to order the Gen4-specific trigger + trigger bar?

i just did the same thing myself on a gen 4 g19. I used glock part #SP00357. I don't think there is a gen 4 specific trigger and trigger bar.

while you're at it might as well put in a 3.5# disconnector
