As a beginner in the world of firearms, I was quite apprehensive at first. But training with Garry at Gamma Gamma Tactical changed all that. His patience, expertise, and ability to simplify complex techniques made learning an enjoyable experience. I now handle firearms with much more confidence and respect.
