Outside Waistband Holster designed to fit the Sig Sauer P320 Full Size, X5, and M17 pistols with the Streamlight TLR-1 light and Align Tactical Thumb Rest Takedown lever mounted to the handgun.  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 has also been confirmed to fit the P320 AXG Pro & TLR-1. Does not fit the P320 Spectre Comp. 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 both inside and outside the waist. 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. The holster's retention is easily adjusted so that the fit can be set to your personal preference.  Some variations in the TLR-1 light body will affect the fit and retention of this holster. We have designed the retention adjustment around these tolerances so that old and new TLR-1 or TLR-1 HL lights will fit.  You can purchase the Align Tactical® THUMB REST TAKEDOWN LEVER from Align Tactical at https://www.aligntactical.com/pages/thumb-rest-takedown-leverFEATURES: Open Muzzle Full Sweat Guard.
