"The MK II target model(KMK-678) had polygon rifling where other models had traditional land and groove riling."

Figures. Wikipedia. That statement concerning "polygonal" rifling is bogus. Glock pistols have "polygonal" rifling, and they do NOT recommend shooting lead bullets in those barrels. You must already know that .22 Long Rifle cartridges have "lead bullets". 10 to 1, if you look into the barrel of your pistol, you will find that it has lands and grooves.
