Just because you own a firearm or a CCL license doesn’t mean you’re trained enough I strongly suggest to take the unarmed and armed security training courses to educate yourself even further. Instructor Nick will show you you don’t know sh*t about firearms, but after his classes you will walk out knowing so much more than you did before walking in.

Nick was a great trainer for the Unarmed 20hr class. I came here because my dad went this school over 20 years ago and he’s getting into the field. I feel a lot more confident than before.

We appreciate you sharing your experience and your strong recommendation. We're glad Nick helped broaden your firearms knowledge and that both the unarmed and armed courses were valuable. Your feedback helps others understand the importance of proper training, and we look forward to seeing you in future classes.
