Also check your firing pin safety plunger isn't binding. I don't think this would impact what you're trying to do here but it's definitely something to watch out for that the spring isn't all hung up in the hole.

I think the firing pin safety plunger was the problem. Before when I had the extractor spring/rod, firing pin assembly installed with the end plate over both, the firing pin safety plunger wasnt moving at all it was binding/stuck. End plate wouldnt go in.

I re adjusted the extractor, where the firing pin safety plunger can move up and down when pressing. Then the end plate slid right in.

Something i ran into with my build, the plastic plunger on the extractor rod was a bit long. My issue was more with FTE/stovepiping once I went to the range. Swapped with an OEM glock part And all was good. Also swapped to a wolf firing pin plunger spring at the same time.

I do recommend polishing your plunger and the plunger hole in the slide as well, if it’s an aftermarket slide.

There’s a video on YouTube somewhere I found that explains how to trim down your extractor plunger if you run into this issue.

Tolerances on these things is weird. Tolerance stacking is absolutely a real thing.

When you swap to the OEM Glock part does it matter what gen you use? Does it have to be gen 3? Most of the OEM Glock parts I see online are gen 5.

I ordered all gen 3 stuff by glock part number on eBay. Only thing I didn’t use that was gen 3 is the extractor and trigger housing. I opted to go with the gen 4 style because I was getting brass to the face. Part number SP30275. Was something like $14 from kmtactical

I just ordered an OEM glock gen 3 recoil spring assembly for $10. The end cap on the recoil spring guide rod just came off and spring went flying when I was fitting slide to frame. The OEM one should work fine right?
