How about your slide; OEM or aftermarket?
I’ve built a few in several calibers and had this issue with a custom aftermarket slide. Switched to OEM and the problem went away. Polishing, lubing and racking a bunch are all good ideas too. The custom slide maker claimed their tolerances were tighter than OEM and the issue was my frame; not their product. Maybe so.

yeah the slide i'm trying it with is oem glock 35 gen 3. the extractor pointy end is sticking up just a hair too high.
i got a reply back from polymer80. i sent them pics and they said the grip holes are drilled too high. the frame was in the jig and i drilled perpendicular to the jig and the jig holes look perfectly round after i drilled thru them. so either there was slop in the jig (not my fault) or the jig holes were out of place (also not my fault).

So are they sending you a new one?

Might as well find the actual areas causing the dragging. Use a sharpie and mark everything which would be a reciprotating contact surface. Move the slide back and forth a few times. Look for areas rubbed hard and shiny. These indicate disproportionate contact pressure points. Just stone or use your polishing cloth to relieve those areas until the slide movement is smooth. Of course, some things, like the disconnector rail, may show harder contact which would be normal.

he said he'd give me a discount on another one. that's when i replied i did everything according to their jig and instructions, so not real interested in paying more than what i already have. awaiting his response.
Which operation did you do first, drill the holes or remove the chunks at the slide?
Although I agree with the break in advise (in general), you can clearly see that the extractor is way too proud, and there's no amount of break in that will fix that.

drilled the holes first.
Then they should replace it. You followed the instructions and this was the unfortunate outcome. Good Luck, i've known a few people who didn't follow the instructions and were still helped out in the end by P80, they usually make things right.

With both sets of rails pinned and installed I have had to file/stone/sand rails into a flat plane.
Have had to square up underside corners of the rear rails too.
Have had a rear trigger housing block that rocked/rotated in its pocket and that was remidied with a credit card shim glued to the forward side of the pocket to take up the space that allowed the movement to take place.

Yeah, P80 is pretty good about that. I was very careful about drilling the holes through the jig, and the front rails still ended up tilted down. Even after polishing and filing, it was almost too tight for a slide, and wouldn't cycle. P80 replaced it, and the same thing happened. They replaced again, and even though I was kind of fed up with it and drilled with less care than before, it came out just fine. I heard at the time that some of their jigs were off by just enough to cause a problem.
Here's a picture (hopefully) showing the angle of the front rails relative to the rear rails.

maybe being that i bought a discontinued 'brownells aggressive grip' model the jig was one of the older ones.
frankly i just wanted to try the poly 80 version because of the supposed better grip angle vs regular glocks. if they do offer to replace, i might see if they could just send me a finished one of these and i'll just do the background check. cheaper for them (no jig), more expensive for me (background check fee), but easier for me and takes 'me' out of the equation.

i guess they just want to keep the jig costs super low. but i really prefer the super heavy duty metal jigs, router collars, etc for the 80% AR lowers. a lot harder to mess up the drilling and routing given the thickness of the jig and the router collar made it real hard to dig into what you weren't supposed to dig into.

i thought i did read about good customer service at polymer80, but i ain't getting it. from the pics he says i mis-drilled the holes and he'd be more than happy to send me another one for $99, which is more than i paid for the one i have. given i read and followed the directions, using their jig/holes and bits, and there is no indication on the jig otherwise, not very happy with them.
Sorry to hear that, they were pretty decent with me a year or so ago. And, yes, I had the Brownell's model. I tried everything to verify that I didn't mess up the process, including pics showing the straightedge along the rails, and I put the frame back in the jig to show that I'd drilled exactly where their holes were in the jig. They even sent me a locking block rail that they'd verified in their own frame, and it still didn't work in mine, so I sent it back. All my communication with them was via email, with Nicky and Shannon, so maybe you can call and ask for them. Shannon's email indicated that she was the Support Lead Supervisor. (Don't everybody swamp them now.)
Good luck, I hope you get a better resolution from them.
So can one use the newer plastic jig to avoid this issue? I presume they're reusable. Other than color, the one below might be the same Brownell's P80 with the aggressive grip texture. Probably explains the nice price.

Their jigs are intended to be single use.
Thanks. Gifted this item too. Going to give the friend a heads-up, and then see how much to purchase the jig alone.
I don’t see any reason they can’t be used more than once, if you’re careful.
I'll ask around for a lightly used one in case anyone doesn't need.
