Given the definition of a polygon being "a closed plane figure composed of three of more line segments", how is the rifling of a Glock polygonal? I look thru the barrel and, guess what? - It's round, just like every other handgun (it would be a little difficult to twist a bullet thru any true polygon). How does this rifling differ from other, more conventional rifling, and what are its advantages?
