Glock extractor plunger - installed backwards?

[gunsrfun1]

Today I happened to notice, purely by accident, that the extractor plunger on my G26 Gen 4 appears to be installed backwards. That is, the plastic LCI (loaded chamber indicator) was resting on the extractor, and the metal end was to the rear. My G19 has the metal end forward against the extractor, and everything I have read says that's the correct direction of the extractor plunger.
I bought this gun used, and I never noticed it before. I have put around 100 trouble-free rounds through it.
My questions:
1) Are the Gen 4s an exception to the rule, or is this truly in backwards?
2) Since I had no issues, can I assume that, technically speaking, the direction of the plunger doesn't matter, except that the LCI won't function?
3) I assume I have not done any damage to the gun, right?
PS - I did reverse it, so tell me if that was a mistake.
Thanks

You are correct. It should be plastic to plastic, metal to metal.

It will probably work ok if it's put together backwards--at least until the plastic-to-metal contact eventually deforms the plastic too much.

I doubt there was any damage. You can look at the spring loaded bearing and the back cover plate to see if there's any flattening/deformation of the plastic where the metal parts touched them. If you're concerned, you can just go ahead and replace both parts--the combined cost should be about $6. Make sure you get the right spring loaded bearing, there is more than one type.

I bought this gun used...

Gotta love it.

Thanks and good suggestion. I took it apart again and checked; everything looks fine. Thanks again.
