Inside Waistband Holster is designed to fit the Sig Sauer P365, P365X and P365XL handguns with the Streamlight Sig version of the TLR-8 Sub or TLR-8 G Sub weapon-mounted light.  Compatible with manual safety models. For this holster to fit correctly, you will need the TLR-8 Sub Sig Streamlight part number 69417 or TLR-8 Sub Sig Streamlight part number 69437.  The holster retention is on the light itself and not the pistol, which means this holster will not work without the light correctly mounted on the firearm. The light information can be found here: Streamlight TLR-8 Sub Light Information This holster does not fit the P365XL Romeo Zero Elite, the factory-installed front sight causes fitment issues.  The holster WILL NOT WORK with any other TLR-8 Sub version of the light mounted on 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.  Features: Full Sweat guard Adjustable retention Adjustable ride height and cant.  Made from .080" thick thermoplastic for durability Open Muzzle for threaded barrels or compensators  Minimal material and smooth edges to reduce printing.
