Bought a factory OR slide for my stock P10. Now it wont eject after a fired round. Does this once probably every mag sometimes multiple times per mag. It stops halfway and locks the slide and the mag from moving. I have to smack the back of the slide forward back into battery, then drop the mag, then eject the spent casing. The next round in the mag is all chewed up from locking the mag and the slide from moving. This pistol had approximately 700 rounds fired with no malfunctions before the slide swap.

Was it a complete slide, with barrel? Or are you using the same barrel from the iron-sights slide?
I can't see what is going on, obviously, but it sounds like maybe a tight chamber if you got a new barrel.
I have a pair of C and a pair of F models in the P-10 series, swapped slides and barrels among them just because I was curious about possible swap issues. Never had any problems myself. But what you are experiencing is something people I know with Springfield Prodigy pistols had, early on, with a slightly too-tight chamber.

If you load up a full mag (I believe 19 rnds) and insert and seat the mag, then pull the slide back and SLOWLY guide the slide home until it is into battery, a round is chambered and then eject the magazine, does the first round in the magazine fall out?
My bet is that the barely might need to be clearance just a tiny bit to fit the slide. Mass produced pistols are designed so thar shouldn't be necessary but every now and then you might run into a fitment issue.
The issue might be where the front of the barrel goes through the hole in the slide. The farther the slide moves back the more contact there is at the muzzle end of both.
It could be that the new slide's recoil spring channel is a little shorter and not allowing the slide to travel far enough back. One way to test that is pull both slides all the way back manually (not on the slide stop) and measure how far it goes past the back of the frame or make a sharpie mark on the frame and see where each slide travels in relation to that mark
I have not fully stripped & reassembled a P-10 slide -- is it possible you messed up something in the parts swap?
I would not expect the recoil spring weight to be that sensitive on the P-10 series. I have run my OR models w/o RDS and w/ RDS. I have put my OR slide w/ RDS mounted, onto an iron sights P-10 using its original barrel and recoil spring assembly. No difference. Granted that's a sample of one person with 4 P-10 models, so narrow sample.
I guess anything is possible but its so damn easy I dont see what could be messed up. The extractor moves freely by hand and doesn't hang up. The only other thing to replace is the striker assembly which comes out as a whole unit so its not rocket science. The gun also works 75% of the time so if I had done something you would think it wouldnt.
Its on its way to CZ today so we'll see what they say about it.
Didn't mean to insult with that question. Since I haven't done it I don't know if it's straightforward or something where, for example, a directional part placed in the wrong direction, would be possible. I don't like to assume others are hamfisted in mechanics, but I have known many people to play around with mechanics while not really understanding things. Didn't want to assume that was you, though.
Got my P10 back today. Hopefully I'll be able to shoot it a little this weekend but not sure yet. Here is what they said they did to it. Not sure exactly what the first part means but hopefully it works now...
“Adjusted and polished breach face lead in. Honed chamber and barrel hood. Cleaned debris from extractor. Functions checked and test fired good with CCI Blazer 9mm 115gr FMJ with customer magazine.”

For the future- I have helped some customers with FTE issues with Glocks & Sigs when the optic plate screw was just a tad too long and interfered with the extractor movement.
Shot 165 rounds through it today no issues. Looking good so far.
