The Sticky Holster design is a unique design that works either inside the waistband or in a pocket. The concept is that the pressure from your clothing/waistband/belt will push against the holster holding the firearm and holster in place. When you go to draw the firearm the friction combined with the sticky skin of the holster will allow you to quickly and easily draw the firearm while the holster remains in place. Over time, and with more use, the Sticky holster will begin to conform to your firearm with your own body heat providing you with a custom fit.Specifications and Features:Sticky Holster MD-4 Medium Holster MD4Inside The Waistband Ambidextrous DrawNo Bulky Clips or StrapsLightweight HolsterClosed End DesignBody Heat Over Time Creates Custom FitStick SkinMatte BlackFits:Bersa Thunder 9Bersa Thunder ProWalther PPSKahr CWKahr P9Glock 43Sig Sauer P239Smith and Wesson ShieldSpringfield Armory EMPSpringfiel Armory XD-SWalther CCPWalther PK380Walther P22Walther PPS M2And similar pattern clones
