Inside Waistband Holster designed to fit the Sig Sauer P320 Compact, Carry and M18 pistols with the Streamlight TLR-8A, TLR-8A G, TLR-8X or TLR-8X G light and Align Tactical Thumb Rest Takedown lever mounted to the firearm. The holster retention is on the light itself and not the pistol, which means the holster will not work without the light mounted on the firearm. Holster is confirmed to fit the Zev Technologies Z320 XCompact with the TLR-8A, TLR-8A G, TLR-8X or TLR-8X G attached to the pistol.  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.  Note:  Gas Pedal, Align Tactical and Tactical Development supporting holsters are not returnable for anything other than quality or workmanship issues.  You can purchase the Align Tactical® THUMB REST TAKEDOWN LEVER from Align Tactical at https://www.aligntactical.com/pages/thumb-rest-takedown-leverFEATURES: Full Sweat Guard.
