Wow...that thing about the pistol being straight in your hand (and lined up with your elbow)is interesting. My muzzle definately points slightly inboard when I hold my pistol comfortably...almost like the grip was designed to be held that way. I can't tell if holding it "straighter" will help my shooting or not...I'll have to test that out on the range.
Does anyone know what caliber he's using? I'm gonna guess 9mm by the way he can keep the sights on target..
