*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. 

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 cause variations in the fit and retention of this holster. We have designed the retention adjustment of the holster around these tolerances so that old and new TLR-1 or TLR-1 HL lights will fit. 

FEATURES

  • Open Muzzle
  • Full Sweat Guard

      Awesome products!! Great and fast responding customer service. I selected the wrong holster model and asked for an exchange before it got shipped out and within minutes they had it taken care of!
      Thanks again!

      Fit

      The holster came in just in time for my next UC op I had to work but the fit was too tight even after loosening the retention screws to get the gun out of the holster was a nightmare and surely not feasible for if I would’ve gotten into a bad situation. Definitely not trashing y’all product at all!! I actually love the look and fit of the holster in the waist band. And after filing down the inside of the holster, it was perfect!

      Great Holster

      Everything fits excellent and it keeps the printing down to a minimum. Retention is also perfect and it is very comfortable.

      Would recommend this IWB Holster.

      First, finding a IWB holster for the Sig with the TLR-1 light is a challenge. This holster is built sturdy and fits well inside the waist band. 4Bros to my call and answered all my questions to ensure everything was good to go. I recommend this holster to anyone.
