At this point, I think the situation is that the gun is working correctly, but that you have an older trigger bar, without the bump. Is that right?
If so, then I can offer a few pieces of information.
First, I see no need to change the trigger bar to a new one unless you really want to be picky about keeping all Gen4 parts in the gun. I know of others who have replaced the Gen4 trigger bar with an older model with no problems.
Second, the modification that was done on your old trigger bar was most likely filing the part that contacts the nose of the striker. If there is a "sear" on a Glock, this is it: the area where the trigger bar contacts (and releases) the striker. Messing around with this will result in what I think the instructor called "undesirable and unreliable consequences".
This is a photo of a trigger bar with the area in question circled:
If that was done, I would not use that trigger bar. Filing the bar in that area is a very bad idea. If you don't know if it was filed, the only way I can think of to make the determination is to set it next to a new trigger bar and see if the cruciform is the same. If it looks altered on the one that was in the pistol, I would get rid of it.
Third, Ghost makes at least two types of connectors. The "Ghost Rocket" has a tab (sticking out to the right in the photo) that must be filed down to fit a particular Glock. That tab is an overtravel stop. If that is not fitted correctly, the gun will not reset. You need to follow the instructions packaged with the Ghost Rocket in order to do it correctly. Moving a Ghost Rocket from one Glock to another may not be successul, it is a matter of fitting.
The other Ghost connector type, the "Ghost Ultimate" is a more traditional Glock connector, with no overtravel stop. This is a drop-in part, and should have no effect on overtravel or the ability of the gun to reset.

the area you circled is what the armorer said had been modified on my supposedly "Stock" , "brand new" glock....I think it is more likely that the Ghost connector just didn't work well with the Gen4 trigger bar...
he did point out that there was no smiley face on my barrel, but also no copper grease - so it may have been new, just had the grease wiped off...strange because the dealer wouldn't even let me remove the slide prior to purchase

Rise to the challenge. Embrace the suck.
Be ready. Be practical. Be humble.
As rash as that sounds I must agree, especially as I am knowledgeable about how to do it and what to look for once it is off !
Maybe that was his concern as well ...

Glock 27 Gen4
I had the trigger reset issue on my gen4 34. Also it had a 6lb trigger instead of the spec 4.5 lb. I bought the Ghost Rocket 3.5 lb kit (connector, springs, etc.) from Brownells. After installing now have a perfect functioning 3.5 lb trigger and no reset issues. 100-003-306 ROCKET GLOCK TRIGGER KIT 1 $39.99. the only fitting is with the new connector.
