Glock 9mm Variations

Here is a handy graphic that I saw on Pinterest that shows in a single graph the variety of 9mm versions there are from Glock.

I sighed at the notable exclusion of the Glock 18 full auto 9mm.

I can really see from this image that all of these can actually use the same IWB holster that I have.
