An ergonomic, mission-adaptable, RDS compatible, multi-positional, deep concealment IWB hybrid thermofolded holster. Its distinctive features enable concealed carry for a wide range of handgun fits from various carry positions while allowing for a full firing grip prior to drawing. The design features passive retention and adjustable tension functionality, allowing a fine-tuned holstered firearm fit and draw feel. This evolution of the IncogX features a series of clips that allow more adaptability to the end user while providing the original design intentions of enhanced grip acquisition, concealment, and functionality. The clips open outward and slide down with the holster, naturally locking in place over the belt. An actuated finger tab flexes to open, allowing quick installation or removal from the belt. An improved clip strut design combines functionality with customized concealment shims that can be easily installed or removed without any tools. All IncogX models include clip strut shims in three different concealment enhancement sizes, 1/8”, 1/4", and 3/8”.
