The thing is that the idea of pistol/shoulder gun didn't exist at the time matchlocks were in vogue. Short gun held in one hand vs long gun held in one or two hands vs on for gun belt in two hands only. Stock shapes were just starting to evolve. In Italy short one hand guns were made with very short shoulder shaped stocks, they were far too short to shoulder. We make comparisons because it's like s o and so, we can do that with dragons and paratroopers similar concept but whole different animal.
