The patented X-FER is a weapon light specific holster, not handgun specific.  

LIGHT SPECIFIC: This means the X-FER locks on to the weapon light system (currently the X-300U-A and X-300) verse the trigger guard like the other holsters available now. 

MODULARITY: The X-FER V2 can be worn Outside the Waistband and Inside the Waistband. It comes standard with an IWB loop. Utilizing it's multiple mounting holes you can affix it to most mounting platforms including Tek-Locs and/or drop leg mounts. You can also adjust the cant and ride height.

SILENCER/SUPPRESSOR: The X-FER V2 allows for you to holster a firearm with a mounted Silencer/Suppressor. 

MINIMALISTIC: Our holster is minimal when in the IWB configuration but still offers concealment, stability and comfort. 

AMBIDEXTROUS: The X-FER V2 is capable of being worn on the right or left. South paws you no longer have to special order a holster.

TRANSFERABLE: Hence the “X-FER”. The X-FER V2 is able to be transferred from one gun to the next as long as the Surefire X-300U-A fits your firearm's manufactured rail (*AC Note* will not work with some firearms). You can X-FER from a Glock to a M&P to a XD to a 1911. It does not matter if you have a compact or full size pistol, as long you can mount the weapon light the X-FER will fit. If it has not sunk in yet….No more having to switch lights and/or holsters when you change your mind and want to carry your other firearm. No more buying multiple holsters for every firearm with the same light!
