In many states the type of handgun used for the qualifying test,,,
Determines what you may carry with your license.
For example in Oklahoma if you take your test with a revolver,,,
All your license will authorize you to carry is a revolver or a derringer.
If you take your license with a semi-auto,,,
You then may carry a semi, a revolver, or a derringer.
At the time I took the class/exam I didn't own a semi-auto pistol,,,
So I rented a semi-auto .22 from the course instructor,,,
Even though I intended to carry a revolver.
It's possible the people are simply not wanting to limit their future carry choices.
