Does this mean if I decide to build a g23 I can use a lower parts kit for a 19 and upper parts kit for a 19? I just have to get a g23 specific slide and barrel?….
 
Recoil assembly will be different. I believe

Along with the recoil spring, different magazine, extractor and ejector as well. Same trigger housing can be used though those usually come in a set with the ejector. I believe someone here had tested out the .40 S&W ejector with 9mm and it worked (and corrected the brass ejection angle). Not sure that you can use the 9mm ejector with .40 S&W.

The parts with the stars on the photo below are items that are different than the G19.
No, G19 upper parts are not the same. Get upper parts for G23 or G32 they are interchangeable except the barrel.

Lower parts for G19, 23 & 32 are the same except the the ejector

If you want to do multiple calibers on a G19 (PF940C or PF940Cv1) you should get a slide for a G23 or G32 Gen 3. Or an aftermarket copy of the same. The reason is the exterior barrel dimensions. The G23 ( 40 S&W ) and the G32 ( 357 Sig ) use a barrel that is larger that the G19 ( 9mm Parrabellum )

So, a G32 and G23 barrel will not fit inside a G19 slide. They have a larger breech block and are too big to pass through the G19 slide. Now, aftermarket 9mm conversion barrels are readily available to allow G23 and G32 pistols to shoot 9mm. Which means if you build your pistol as a 40 S&W or 357 Sig, you can also shoot the 9mm by swapping the barrel with an aftermarket conversion barrel.

If you build the pistol using a G19 slide, you cannot later change to 40 S&W or 357 Sig... there just isn't a barrel to do that, since the wall thickness of a 40 cal barrel becomes too thin with the G19 exterior barrel dimensions (which is why Glock made the G23 and G32 larger in the first place.) With a G19 slide, you have to stay with the 9mm Parrabellum chambering. (or buy a second slide & barrel)

That's my advice to any new builder. Build the pistol as a 40 S&W or 357 Sig. The when you want to shoot cheaper 9mm, you swap the barrel, magazines, recoil spring, and ejector into the same slide. You can also change the extractor parts too, but I've found the 40 S&W parts do a pretty good job on a 9mm.
