Enigma Assembly Instructions – Stress FreeLeg Leash Instructions and TroubleshootingEnigma SafetyDesigned to accommodate the size and mass of light-bearing concealment holsters, the Light Bearing Enigma is based on the dimensions of our popular Floodlight IWB holster, but will fit many other holsters which feature the same wing and clip attachment strategy. The Light Bearing Enigma uses four screws to attach the faceplate to the clip mounting holes on the face of the holster. Please be sure that your holster can attach all four screws in order to properly support the system. Do not modify your holster or Enigma.
