The X-FER from Armordillo Concealment is a compact, minimalist kydex holster that accommodates a weapon mounted light. There are other holsters that are similar on the market but few, if any, work with a weapon mounted light.
The holster is called the X-FER because it can be transferred to any handgun that will fit a weapon light. The holster actually locks onto the light instead of the handgun.
