I just saw this (NRAStore.com - Product Detail) slide holster on the NRA web site. It has a little plastic window for your concealed carry permit card. It struck me as a pretty poor idea, because if a police officer ever wants to see your card, you'll basically have to reach for your gun. In practical terms, it also seems like it'd get bent up, but that's less of a concern.
Am I overthinking this one?
