 It can incapacitate an attacker for up to 40 minutes. No need to go DEFCON 1. We just need protection to ensure we can defuse the situation and drive the threat away. I'm really liking this product a lot. I've trained with firearms for many years. The Berna pistol that Berna sent me was one of the easiest to learn and use. If you don't own a firearm, it's a great option to have. Made in America, legal in all 50 states, requires no background checks, and shipped right to your door.
