Last night I noticed that my XD has a right hand twist in it's rifling and my SA 1911 has a left hand twist. I can't remember when or where I heard or read (or dreamed) that one or the other (probably the 1911, since Browning seemed to have a reason for everything) had a purpose having to do with the torque of a gun as a bullet goes through the rifling. Most people are right handed, and IIRC, the rifling was designed to go (left? right?) to use the torque to help a shooter keep the gun straight. If this is so, then why wouldn't all handguns have the rifling going in the same direction? Or why not have barrels with right or left rifling as an option so right handed and left handed shooters can both take advantage of this torque factor (if it indeed really exists)? Anyone know anything about this? Could it be that in Croatia there are more left handed people? Or maybe Browning himself was left handed? Did I dream this? Or has anyone else ever heard anything like this? Peace, D.
