To those who never clean (or rarely clean) their Glocks I have a question. Have you carefully inspected the bore for corrosion or pitting? When I was a youngster (OK it's been a while now) I remember that we could look down the bore of a rifle or shotgun and see how well the owner cared for the weapon by observing pitting in the bore. So we learned to clean our weapons after each outing. I imagine primers and powders are less corrosive now and materials use to manufacture weapons has advanced considerably, but is the possibility of bore damage completely gone now even if one doesn't keep their weapon clean? And is the Glock a special case or could we expect all modern pistols, rifles and shotguns to be immune to bore damage?
