Well, if your friends are prepping for their own CHL's they may well
have a gun of their own already.

Under the Castle Doctrine they can protect themselves in their home.
Their gun should be loaded and available to fire immediately (either safety-equippped
or a Point-and-shoot such as a revolver or a Glock). It should not be locked up or unloaded.
Keeping it away from children is necessary, but if they are not parents, then the gun's availability
is paramount in case of a home invasion.

Under the MPA (Motorist Protection Act), they are also able to keep a concealed
handgun in their vehicle.

Knowing this, your friends have the ability to be self-sufficient in their defense while
at home, or driving. That should take some of the burden off you.
