They make a lot of hand gun rounds close to the same size as the 9mm, the 10mm is pretty much the same size as the 40S&W so why not take it a step or 2 further with a 11mm which would be .43 and close to a 45acp or even a 12mm which would be .47 and just in-between 45acp and .50cal. Just curious and board at work.
