Unlike millions of pepper spray or aerosol defense products which are one and done, ASP Palm Defenders are engineered to use dispersion devices which can be reused following deployment.  Each Palm Defender uses a proprietary, and replaceable, OC (Oleoresin Capsicum) insert which is precision-machined from aerospace aluminum and solid brass.

The Palm Defender Heat Inserts are compatible will all of the ASP Key Defender line and each contains approximately 6 1/2 second bursts. Now about bringing the heat. The ASP "Heat" is a formulation of maximum strength, law-enforcement grade OC comprised of 10% Oleoresin Capsicum, 1.33% major capsaicinoids, and two million Scoville Heat Units (SHU).

Note: Pepper spray cannot be shipped to AK, DC, HI, MA, NY or Puerto Rico, The Virgin Islands or internationally.  May be shipped to other locations via ground service only.

  • 3 grams
  • 3 half Second Bursts
  • Effective Range Three Feet

In addition, the entire Palm Defender and its specially-produced valve system and patented dispensing mechanism is O-ring sealed to prevent an unwarranted discharge. Having a component based dispersal system is a significant advantage over the one-and-done dispersal systems, in that it facilitates safe training. Using the Palm Defender with a test insert of harmless, inert aerosol allows for proper law enforcement training up close and personal without the possibility of inflicting actual harm.

The Palm Defender Heat Inserts are compatible will all of the ASP Palm Defender line and each contains approximately three 1/2 second bursts.
