    Faster: The reversed angle matches up with the pad of your thumb sooner than the factory button. You will find the gun in your hand just by grabbing it. Weak hand drawing becomes faster as well.

    More Reliable: The wider release button means you have even less potential to miss the activation, especially on thigh rigs or mounting systems that push the holster away from your body. If you have ever found yourself pulling up on the gun before hitting the release you've noticed that gun is difficult to almost impossible to get out. The additional leverage of the Nub Mod fixes this stress induced or poor training problem if it ever arises due to the increased surface area for the thumb to engage.

    Simple Install: Simply press the larger nub piece over the factory button from the inside of the holster. Align the smaller narrow piece with the top of the larger one. Insert screw and tighten with supplied allen wrench. You may add Loc Tite or finger nail polish to the threads if desired.


    Level III users must buy the SLS Nub!

    1911 (and other guns with large thumb safety's/decockers -Sig, M&P with safety-) users will find the safety in the way. You must buy the 1911 Nub! Does not work with HK USP's with the safety in the 'SAFE' position. This adds 1/8" toward the weapon from the factory lever.

    In 2020 Safariland started releasing some new ALS levers. If your lever has the part number 'GL04' on it (as seen from inside the holster toward the front as worn), you will need to file the lever flat as shown in the last image to make the Nub Mod fit.
