Eyes and ear protection are mandatory. Hand guns can be any caliber from 9mm to .45 auto. However, no magnum calibers are allowed. Holsters must fit your gun and cover the trigger guard. The holster cannot be a shoulder style rig, cross draw, SOB(small of back), ankle or thigh. You should have at least one magazine holder that will hold 2 magazines or 2 speed loaders if you are shooting a revolver. Four magazines or speed loaders is better. All should be retained by an appropriate wide sturdy belt capable of holding this much weight. You will probably need about 100 rounds of ammo or more. Please do not bring unreliable handguns or questionable ammo.
