Would someone be so kind to post what parts are compatible or able to swap on a Gen3 and Gen4 and vise versa in each caliber. If I knew I would and I'm sure this would be greatly appreciated by all.

Gen 3 trigger bars are changable with a gen 4. Recoil springs are if you buy the adapter.
All other parts will fit, with the exception of the ejector housing. The Gen 4 has a slimmer housing for the slimmer grip.
Not sure on the extractor and plunger.

I changed several parts out on my Gen four. I have a G27 so the recoil spring/rod was not an issue. Same as the Gen 3.
I used a Gen 3 smooth trigger bar, trigger spring, connector from a Gen 3.

Just a information post. I guess to answer any questions myself or anyone else may have on the 2 Gens interchangeble parts.

We just discussed this.  This should help:

But is that the same for the 22,23,21? I see it says G19

Not all of it will be, but its a good start.  

For the 23 it will defnitely apply.
