"I recently attended the Basic Handgun Class at Delta Tactical. I am a woman who is over 60. It was a fantastic class. I've been around guns for many years. But, I have never shot one. Robert, Dan, Amy and the rest of the crew gave us a lot of great information. When we went to the range, they always gave us encouragement. They never became impatient or frustrated with us. We now know the basics and feel empowered knowing how to protect ourselves and our property. An intermediate class would be beneficial to continue to become more knowledgeable. I would definitely recommend Delta Tactical to anyone, no matter the age, who want to learn how to use a handgun. Thanks you guys for a great day."

-Toni Shannon ★★★★★

I have been recommending it to all my friends now."
