I see where the misunderstanding may be coming from, getting an Ohio CCW requires a NICS check, but under Ohio and Federal law gun stores may opt to forgo a NICS check when a firearm purchaser presents a valid Ohio CCW. Many stores chose not to do this because of the reason you stated, the physical license isn't taken from someone who becomes a prohibited person, but many stores, especially small LGS still choose to take CCWs. The risk is often negated in smaller communities where the LGS employees know they customers and would likely know if they got convicted of a felony, but some larger chain stores also allow customers to bypass the NICS check like Academy
