Outside Waistband Taco Style Holster designed to fit the Full Size and Carry P320 series pistols with Streamlight TLR-1 weapon-mounted light. The design also accommodates the M17, M18, and X-Five models. 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 We used the P320 key with the TLR-1 HL light when we designed this holster; using other keys will place the light farther forward on the grip, changing the position of the pistol in the holster. 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.  FEATURES Open Muzzle Full Sweat Guard Adjustable Retention Adjustable ride height and cant Made from .080" thermoplastic for durability Minimal material and smooth edges to reduce printing Compatible with Red Dot sights, including the Romeo 1 and Trijicon SRO Proudly Made in the USA  Outside waistband attachments are explained here: 4BROS Four Brothers Holsters Outside Waistband Attachments Explained Magazine Pouches for these models can be found here: Sig Sauer P320 IWB Magazine Pouch Sig Sauer P320 OWB Magazine Pouch *We strongly suggest you apply a removable thread locker to each screw of your holster after you receive it to prevent lost screws while the holster is in use.
