Sig Sauer P320 with TLR-1 IWB Holster

This is our Inside Waistband Holster designed to fit the Sig Sauer P320 line of pistols with the Streamlight TLR-1 HL weapon-mounted light.

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.

Confirmed to fit the P320 Carry, Full Size, XFIVE (X5) and DH3 models. It will also fit the Brouwer grip module with the light installed.

Does not fit the P320 Spectre Comp without retention adjustments. 

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 retention of the holster is easily adjusted so that the fit can be dialed into your personal preference.

The profile of the holster is cut to allow it to work with larger red dot sights such as the Trijicon SRO and Sig Romeo 1.

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.
