I know a bit, but admittedly not everything. I was hoping some of you gurus could chime in and correct my mistakes. Did I forget any variants? Did I include variants on models that didn't exist? Did the 21 come in FDE for Gen3 models or only Gen4? Was there a Gen2 20? Was there a Gen2 36? Was there a Gen2 27? Any variants on the .357 models? I am trying to be as thorough as possible, so if you see something wrong please let me know. I want every single Glock model and variant of that model on this list.
