Retention Kit

If you are attaching an adjustable retention holster to your Enigma, the Fixed Retention Kit is the best, easiest, most reliable way to do that. Replace the rubber retention adjusting washers on your holster with the correct combination of rigid spacers in this kit to match your preferred level of retention, and your Enigma will assemble nice and tight with no wiggle or movement. See instructions here. 

The Dark Star Gear fixed retention kit will allow you to convert your adjustable retention holster to a fixed retention holster.  This will allow for increased torque on the screws, resulting in an increased clamping force and prevent concealment wing wiggle, loosening of retention, and if you’re an Enigma user, you ensure your faceplate stays tight.

This kit uses multiple spacers to get the right feel and fit for your holster.  The thicker spacers will allow for coarse adjustment from 0.125″ to 0.3125″ in 1/16″ increments, and the thinner spacers can be added to further refine the feel to get things just right.  Simply measure the ideal retention setting on your current holster, between the holster halves, and select the thick spacers that get close, and add in thinner spacers as needed to fine tune the feel.

The kit includes four 0.125″ spacers, two 0.1875″ spacers, and six 0.015″ spacers, allowing the kit to work with the most common holsters on the market using 0.250″ rubber spacers and our holsters using 0.1875″ EPDM spacers.

    Thanks to the Phlster Enigma Fixed Retention Kit, my Ruger P94 is very secure and easily accessible in the PJ Holsters custom holster, assembled in the Phlster Standard Faceplate. Thank you Phlster for inventing the Enigma.
