Mike, “I wanted to tell you what a great product you have. I am an NRA Training Counselor, a CA POST firearms instructor and I taught a class of new pistol instructors last weekend. In short, it allowed them to realize the importance of having every effective tool available to teach a new shooter the importance of indexing the trigger finger. I have used other devices to try to illustrate this concept, and it was amazing how quickly each of the student instructors kept returning to your product to incorporate it into their teaching 6zlcfhv. It is well constructed, durable and easy to use.
