“Train, keep training, carry your gun whenever you legally can.” – John Benner

Ammunition counts have been reduced for our classes. You can find the updated minimum requirements on the class page. Please make every effort to purchase your own ammunition well in advance of your scheduled class. As a reminder, if you are borrowing a TDI gun, we do not allow reloads or remanufactured ammunition. We will accept remanufactured ammunition from Midwest Ammunition or Black Hills Ammunition. If you are unsure about what ammo to purchase, please give us a call or send us an email.
