congratulations. Was it difficult to get?
I mean, not too bad. First I had to take the NRA's day-long Basics of Pistol class. Then you take a one-day Basic Instructor Training that has a shooting qualification component. It wasn't hard for me, but some struggled with it a little. That makes you an "instructor," but you still have to take a class for each discipline you want to teach. So I took the pistol instructor course which was another very long day of range and classroom time where they teach you how to teach the pistol curriculums. All in all, 3 long-ish days, some studying, and about $700.
A humble brag here since I'm on the subject... I shot the qualification with a double-action S&W revolver. The NRA training counselor said I was the best DA revolver shooter he had ever seen that wasn't a nationally ranked competitor. Maybe I missed my calling!
I'm not exactly sure what I am going to do with the credential yet. I working on putting together some training focused on lawyers where I can provide both Continuing Legal Education credit and an NRA course completion.
