Well since the wording hasn't changed;
6 c. A firearms safety or training course that is available to the public and is
7offered by a law enforcement agency or,
Yes to all of these..........hunter safety, shooting competition, military service, the MD class????
And I guess the Maryland Police Firearm Training will suffice. It take about 30 minutes. It's not an exam, there is no test. If you can click a mouse you'll have your certificate upon completion.
