What course? Do they need Live Fire, or is it just a "get your LTC ticket punched" class?
If the latter, any NRA Home Firearm Safety course will do.
If they need live fire, the traditional NRA Basic Pistol is nowhere, anymore, due to the change to blended learning. You'll need to find either a hybrid course as we run it at Southborough - HFS, with a trip to the range, or a proprietary course from a "commercial" source.
