Can someone take a look at their P07 or P09 disconnector (and maybe post a pic, if possible) and see if you have this "nub" on it as mine does, shown in the pic attached?

Well, I can’t seem to post a pic but I attached the link.

Is it giving you issues?

No"nub" on mine; but unless you're having problems, I'd be inclined to ignore it

I am having issues. I spoke to CGW and they don't believe the nub is an issue either. They think it's related to the relationship between my trigger bar and disconnector. They recommend a good polishing. Here's a short YT video of the issue.

The p09c nocturn I recently bought is knubbed.

I had that problem once reassembling my P07 after a polishing. I didn't have the trigger bar spring properly seated and it slipped behind the bar. My 07 was a dog from the factory, but is a pleasure to shoot after a thorough polishing.

I completely disassembled it last night to check for anything obviously wrong. Everything looks as it should. I polished the trigger bar, hammer, and sear contact surfaces and reassembled it. The issue is still there. Not sure there’s anything left to do but call CZ Monday and see if they will take a look at it.

It looks to be something akin to a casting sprue, where the powdered metal enters the mold.
https://en.wikipedia.org/wiki/Sprue_%28manufacturing%29
This part (like all the other small CZ parts) is made by the "powdered metal process". A method of making highly accurate parts very inexpensively.
When they break off the excess sprue material, they break at random places; some high, some low. The designer knew this and provided a divot. In this way, even if they break off "high" there is no interference with mating parts. The objective being: to eliminate secondary or follow-on manufacturing steps (such as hand grinding) that add a lot of cost without improving quality.
