I'm starting to reload for my C9. I know this is a low end gun, but I just had to have a 9mm semi and didn't want to spend a bunch. I have other defense handguns. Anyway, it's a blowback operating pistol, relying totally on the blowback of the fired cartridge to operate the action. Here's my question. Should I load a heavy bullet, vs a light bullet, to help with operating the action? I know that a heavier bullet kicks more, given the same pressure, so my feeble mind says it will help. What do you think?
