Yes that's true. I think it would be a lot better if everyone at least used mid caps because winding is stupid, even if you do technically have more rounds available which is useful. More manufacturers should sell their guns with mid caps but is guess it is more appealing for a beginner for a gun to have a 450/300 rounder then they don't need to buy new mags straight away or be using a speedloaders every 5 or 10 mins
