Imagine a 10mm glock with the thinness of the G19. Is it even possible or does the slide thickness mandate the current 10mm size? Anyone have any idea how many rounds a single stack 10mm might hold? I would think at least 8, perhaps 9, not sure. Would anyone consider purchasing such a gun if Glock ever made it? I would if it held at least 9 rounds and were no larger or wider than the G19.
