Hey guys, and ladies maybe... Got a new sig p226 with threaded barrel and night sights. Haven't shot it yet but am worried about the barrel cap... I notice when I decock it several times, the cap tends to loosen no matter how hard I tighten it. Are threaded barrel caps none to fall off and go missing often? Would I be smart to just invest in a regular barrel? Any input on this topic would be useful. Thanks!
