ASP Defender OC (pepper spray) devices are unique in form and function. Unlike other self defense sprays, Defenders are designed to hold and activate horizontally. This has the benefit of helping to ensure the spray goes where it’s meant to, minimizing the risk of spraying in the wrong direction. It also supports the Defender Forward protective/reactive body position that ASP teaches in its “”Be Your Own Defender”” (BYOD) training classes. Defenders are able to operate this way thanks to a proprietary aerosol canister and valve system (together called the Insert). The Insert is replaceable, so if used or when a recommended change date (marked on valve) comes up, you don’t have to throw away your entire pepper spray device. Just discard the inexpensive insert, and reload the Defender with a new one. The Sport Defender model is made of the same tough polymer used to make gun parts and other equipment built for demanding applications. It’s molded with a faceted surface for a secure grip and unique appearance. Like all Defender models, it’s compact and discreet, so you can carry it anywhere. It features a quick, intuitive thumb-release safety, O-ring sealed dispersal port, and tough forged steel pocket clip. Its solid brass actuator has a hole for attaching to your key ring as an alternate carry method.
