In use by the FBI’s Hostage Rescue Team, and hundreds of Federal SWAT, Local SWAT officers, military teams and competitive shooters.

Below are all the details, or just read the product reviews and take it from other shooters: if you run an ALS holster, you need the Nub Mod. 


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.  

Made in the U.S.A., this aluminum product is blasted and finished with mil-spec anodizing.

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.



Mil Issue M17 & M18

Specifically designed for, and will ONLY work on the new Safariland Holsters with the ‘SG-Mil’ levers, as issued to the U.S. Military for the M17 and M18 Sig Sauer Pistols. Again, this ONLY FITS U.S. Military Issue Holsters! If you have a civilian model holster for the SigP320/M17, buy the ALS NUB MOD!

Fixes the angle and increases the width for a more reliably draw. Chamfer on the inside piece to clear the safety and eliminate the chance of deactivating the safety when you draw straight back on the Nub Mod™.   Blasted for low glare, Mil Spec Anodized aluminum for a tough finish, and of course 100% USA Made.

Designed for Level I use. While we have had users put a washer behind the top T-Nut and continue to utilize the SLS Hood, this is not recommended as it WILL still drag on the hood. Will not interfere if hood is simply left down.


User assumes any risk associated with modifying their holster.

    Item is exactly what a user needs if using safariland ALS system. This gives you that extra edge literally and if used for serious applications it a tactical advantage.
    Very nice received my full order in less then 48 hours. The order was hand boxed and handled in house personally as my invoice was stapled nicely with a nice gift of a company pride sticker&patch included…
    In my opinion every company should take pride In The product and themselves.
    I’m extremely happy as a customer with my full purchase as items came exactly as described, also the shipping process I would say hands down extremely quick.
    I’ll be recommending this product along with the other items I purchased to everyone as the products are great, and the business is even better…
    Purchase with confidence.
