Named after the world’s fastest striking venomous snake, The Death Adder, The Adder System™ is a U.S. Patent Pending exterior weapon concealment system designed for speed, security and ultimate concealment on a wide variety of clothing.  We have both the jacket and vest in the shop and they are very heavy duty, high-quality products and feel they are actually priced too low.  Learn more at

When used as a pocket holster it is ideal for concealed carry of smaller frame handguns such as the Smith & Wesson Bodyguard .380 or the Ruger LCP. The pants you wear must also have enough room in the pockets to comfortably conceal the firearm. If you wear looser pant styles, or cargo pants with multiple pockets this might be a comfortable option for you.

A pocket holster is also a good option when carrying a firearm in a bag or purse. The fully-covered trigger will guard against small objects getting in the trigger guard causing an accidental discharge.
