The ASP® Palm Defender is made up to law enforcement standards but is the perfect self-defense weapon for civilians as well. The durable aerospace aluminum body is lightweight, yet powerful enough to be used as a striking weapon. On top of that, it contains a firing system for deploying pepper spray. Each palm pepper spray comes with one 3-gram pepper spray cartridge that fires up to 3 half-second bursts up to 3 feet. The ASP palm defender pepper formula inside contains 10% OC (Oleoresin Capsicum) and measures at 2 million Scoville Heat Units, so this will cause an instant burning sensation to attackers upon contact, forcing their eyes to close and difficulty breathing. To fire the spray, there is a 2-step activation. First, the safety actuator, which prevents accidental firings, must be disengaged. Once that is done, a simple press of the tail-end activation button will fire the spray from the tip of the baton. On top of that, this palm pepper spray has a detachable key ring that makes it easy to attach to keys and carry in a purse or pocket. This also allows you to swing your keys as a striking weapon for another self-defense option.
