This is something I should have known by know but only a couple years into handguns. So still learning. If you could be so kind and explain "cant" I believe it is the angle of the gun? Secondly, when people speak of "I use it a 2:00 or 3:00 position" is that the butt of the gun? Meaning if the butt of the gun was at the 12:00 position the gun would be straight up and down? Sorry for the lack of knowledge. I would appreciate any input. THanks.
