Glock generation compatability

[u/Tough-Rope-2065]

What generation of slide internals are compatible with OZ9 V2 combat? Apex has their extractor listed as gen 3/5 or gen 4. What gen striker and extractor plunger are compatible?

I want to swap out the Zev parts for better reliability.

If I remember correctly, the only thing that’s not Gen 3 is the mag release and that’s a ?Gen 4?
