Inside Waistband Holster designed to fit the Glock 43X MOS, 48 MOS, 43X Rail, and 48 Rail handguns with the Streamlight Glock version of the TLR-8 Sub or TLR-8 G Sub light mounted to the pistol.  For this holster to function correctly you will need the TLR-8 Sub Glock Streamlight part number 69411 or TLR-8 Sub Glock Streamlight part number 69431  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. Product Details: Information for the Streamlight TLR-8 Sub can be found here: The holster WILL NOT WORK with any other version of the TLR-8 Sub weapon-mounted light. 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. The holster is designed to accommodate a red dot sight mounted to the pistol Optional Modwing includes 2 inserts to allow the user to adjust the amount of leverage placed against the inside of the belt to reduce firearm printing Proudly made in the USA.
