Polygonal rifling? What I hear is that most glock users want to replace it... as it could not take lead... IMHO wont be getting one even if its cheaper. The main reason I got a Steyr is so that I maybe be able to use any ammo that is available without failure. Perhaps it is good for those who can afford brand new FMJ ammos.
If I could get if for free.. by all means ship one to me, just pay for the shipping.
