Before RK Campbells article on Coated Lead Bullets I honestly had never heard not to use lead bullets in Glocks. Glocks armors manual states "Use of non-factory loaded ammunition or ammunition loaded with non-jacketed (lead) bullets will void the warranty." (ARMORER'S MANUAL, © Glock 2009, page 82) Upon further research I found that Glock barrels use the polygonal rifling which is designed to optimize performance for jacketed bullets with inconsistencies. From what I understand if you look down a Glock barrel its in the shape of a hexagon. The polygonal rifling is not your typical rifling there are no grooves
