My understanding is that polygonal barrels (as in Glocks & H&K's) have somewhat rounded lands vs. the sharper lands on more conventional barrels. Logic tells me that a more rounded edge will not "cut" the bullet like a sharper edge will. If this is true, how is it then that polygonal barrels will be more prone to fouling from lead bullets (and pose a greater risk) than a jacketed bullet?
I have shot thousands of rounds of lead bullets through my H&K USP45 with no problem.
