It comes with the smooth face trigger and the connector drops in. The sight setup hasn’t changed.
I assume you mean the 17 comes with the smooth face trigger, not the 19; I’m interested in a 19. However, if the Gen4 19 comes with a smooth face trigger that’d be great.
Should be drop in if it doesn’t come with.
it doesn’t, but the gen3 smoothface trigger drops right in.
Where did you get your info? Seriously just curious.
my local glock armorer has done a few.
i’ve also found forum posts with google where others have done it. the gen 3 trigger/trigger bars are interchangeable with the gen4’s. no fitting required. 
He’s already playing with Gen4 G19s?
i was referring to the gen4 17/22’s.
however, the gen3 trigger mechs will also drop into the gen 4 19/22’s when they come out.
call glock tomorrow, they’ll confirm all this.
It sounded like you were saying that the Gen4 G19s did not come with smooth faced triggers to me and I was asking how you know.
I know about the Gen G17 - I have one.
After debating this for a few days, I decided to go with a Gen3 19 RTF2. I got a good deal on it and I’m just not sure how reliable the Gen4 19s will be in the first batch. I fondled a Gen4 17 and the grip didn’t feel that much better to me. I don’t have a problem with the size of the grip so the changeable back straps weren’t really an issue. The RTF2 is rough but it was nothing a little sandpaper didn’t cure. After working on it for a little while the grip feels great; not rough like sandpaper anymore but it has more texture than the standard Gen3. I wore it around the house some this evening in an MTAC and although I can tell a difference in texture it wasn’t uncomfortable. I plan to install a set of Warren’s on it this weekend and then put a few boxes through it. I believe I’m going to be very happy with it, I can adjust to a different grip easier than having doubts about a Gen4 if it were to have some issues out of the box.
Thanks everyone for your input.
you chose wisely, my friend. here’s mine (totally dig it):
