Sig Sauer P320 with X300 & Align Tactical Thumb Rest IWB Holster

Inside Waistband Holster designed to fit the Sig Sauer P320 Full Size and Carry pistols with the Surefire X300U-A or X300U-B light and Align Tactical Thumb Rest Takedown Lever mounted to the gun. 

The holster retention is on the light itself and not the pistol, which means this holster will not work without the light mounted on the firearm.

This holster will also work without the Align Tactical Thumb Rest Takedown Lever mounted to the pistol. 

This holster will fit the M18, M17, X-Five, and the P320 AXG Pro so long as the X300 light is mounted correctly.

Note:  Gas Pedal, Align Tactical and Tactical Development supporting holsters are not returnable for anything other than quality or workmanship issues. They are specialty items with aftermarket accessories that impact comfort and concealability inside and outside the waist.

It does NOT work with the P320 Spectre Comp.

Product Details:

Our holsters are vacuum formed with a precision machined mold designed from a CAD model of the actual firearm.

Each holster is formed, trimmed, and folded in-house. Final fit and function tests are done with the actual pistol and light to ensure the holster fits the gun/light combination and has the correct amount of retention.
