Springfield Grip Modules? S-M-L

Haven't seen much discussion for the Springfield branded modules. Am I missing something, but I can't find any photos or dimensions outlining the differences between small, medium, and large? The 4.0c comes with a small module, and although I have small to medium hands, I'm starting to think I may need more space on the frame for my support hand. Wondering how much wider the medium or large is? And to confirm, the only difference in sizes is the width and not the height, right? Appreciate any info!
