The SLS Nub is what is needed for users running Level III Safariland Holsters with the ALS lever and the SLS hood. It also works with the ALS only (Level I) holsters for those with a larger girth to allow a smoother contact with the body over the ALS Nub Mod.
Upon engaging the SLS hood downward with the thumb, the users thumb cannot help but land on the Nub Mod, releasing the weapon into the drawstroke.
Slightly grooved to keep the thumb in contact with the lever, blasted and hard anodized black for a long lasting finish. Made in the USA.
Includes all hardware for installation. Video below, step by step pictures click here. SLS Install
