[Jammer Six]

I recommend other instructors and other ranges to every class I teach, and I tell every class that trying to introduce someone to shooting by taking them to a range is like trying to introduce someone to the ocean by taking them to a small lake. The world of shooting is huge, and sometimes I list a few (or a dozen) different examples.

Then I tell them that if they take lessons from other instructors they will quickly realize how limited my field of expertise really is.

Someone who tells you their way to shoot is the only way is marking themselves as someone to avoid.
