X300 Holster - X-FER Universal Holster for Surefire X300

(Works with the Surefire X300U-A or B on Most Firearms.)

Our X-FER X300 Holster works with almost any firearm as long as the Surefire X300U A/B fits the stock firearm rail. (*May not work with after market rails or rail adapters.) 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 X300U to the firearm 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!

Our PATENTED X-FER X300U Holster is a Surefire X300U specific holster (not handgun specific). Works with the Surefire X300U light on most guns. 

WEAPON LIGHT SPECIFIC: This means the X-FER X300U Holster locks on to the Surefire X300UA, X300UB light body mounted to almost any gun.

MINIMALIST: Our X-FER holster is a minimal IWB design made for concealment, stability and comfort. Can also be worn outside with an OWB Kit.

AMBIDEXTROUS: The X-FER is capable of being worn on the right or the left without having to special order a holster.

TRANSFERABLE: Hence the “X-FER”. Our patented X-FER X300U Holster is a light specific holster not a gun specific holster, so it fits the Surefire X300U on most guns. Each of our X-FER X300U Holsters is Crafted and Formed over our Proprietary, Precision Aluminum Molds. Our molds are CAD designed and milled in house so we can ensure the consistency, fit, quality, durability, lightness, comfort, & uniformity of features for each and every holster we make, regardless of the gun it is for.
