I also failed to mention in the previous post that when I pushed the trigger bar forward and a pulled the trigger back and forth that it was smooth throughout the pull.  No catches of any kind.  Also, when I removed the trigger to file the trigger notch in the frame, I also changed out the mag release for an HBI mag release.

I just came from the range.  The trigger reset issue did not heal itself while I was gone. ;) When the trigger does not reset, it is dead. There is no spring tension against it.  As I said before and verified this afternoon, the P-10 F slide works great on my P-10 C frame.

This is a head scratcher.  If the slide is moving back far enough to eject the casing, then it's moving back enough to reset the trigger, so we can pretty much rule out short stroking.  My gut still thinks the trigger bar isn't popping up fast enough to catch the striker or the striker leg is too short for the tolerances in your slide/frame.  What ammo are you using and how's ejection?  Factory springs are pretty stiff, I'm using a 13# in my P-10F with minor PF loads and they still land 5-6 feet away.  Conceivably,  if weak ammo and a stout recoil spring are only allowing the slide to move far enough to pick up the next round, there might not be enough "dwell" to let the trigger bar pop up to catch the striker?  Sort of like an AR bolt outrunning the hammer.

When the trigger resets, does it sound like a sharp snap or is it more like a dull thud?

Can you post a video?  Mainly I want to see how quickly the trigger bar pops up when you press in on the disconnector nub.

I had a problem with my P10C not resetting every time after installing the new CGW striker also. After reading this post and trying the suggests in the post I still had a concern. I call David @ CGW and he stated that the striker spring may be the concern.
I reinstalled the OEM striker spring on the new CGW striker and the concern was resolved! I now run a Wolff #5 glock spring and it is works great!
Not sure if you had tried a different spring, but I wanted to share in case you had not.

I have a 15# recoil spring on both my F and C. I reload and am shooting 145 Bayous over N320.  Chrono around 875 in my C.  Probably will go 885+ in my F. Since I have been mostly shooting the F slide on the C frame, I know with this combination the brass falls about 6 feet away, give or take.  I know that the brass from my F slide and F frame does not fall at my feet but I will have to shoot it again to tell you exactly.  When the trigger does not reset, and I rack the slide to reset it, I only have to move the slide .75 of an inch to reset the trigger.

When I dry fire and hold the trigger down, then rack the slide with the trigger still down, then let off  the trigger, I get a click on reset. I'd say it is somewhere between a snap and a thud but it sounds the same whether I am doing it with the F or the C.  When I dry fire and let off and rack the slide, the trigger resets but I don't hear the click over the sound of the slide. Same on both guns.

Let's say the striker is over running the trigger bar.  How do I correct that?  Since I am IT challenged, I will have to beg my wife to help me take and post a video. That may take a day or so. 

Earlan, thank you for your time and knowledge.  I know you have plenty of things to do besides trying to sort this out for me.

I had wondered about that, but since the F slide works on the C frame I had discounted it.  However, it is an easy swap. I will give it a try.  Thanks for the suggestion.

Okay that explains a lot.   I must have missed the part about swapping slides.  Basically, tolerance stacking is letting the slide overrun the trigger bar.  It could also just be the differences between the trigger bars.  I bought 2 P-10Cs a month apart and they had drastically different trigger pulls.  In the picture below, both are pulled to the rear, but the nub is cut differently between the two, and you can see how much lower one sits.  The one on the right (FDE) worked fine with the slide it came with, but if I swapped on the Black pistol's slide, it wouldn't catch half the time.  Compare the trigger bar hights in both frames and see if there's a big discrepancy.

Here are the frames side by side.  The F is on the right and the C on the left.  It looks to me like the F might be slightly higher. Shot the F slide on the C frame at a local match Saturday.  No problems, reset every time just like it should.  I think I will just tear the F down and put it back together very carefully.  Who knows, maybe that will work.
