Level 1 and Level 3 use.
This is NOT 'longer' or bigger than other Nubs, it simply fits the longer lever design from Safariland imaged below!
Starting 2024, Safariland® lengthened the lever on the 6000 series RDS and RDSO holsters for Glocks and SOME common pistols. If your lever looks like the image below, this is what you need. If not, click here for lever shape page!
Washer included for level 3 users, screw has threadlocker pre-applied.
Due to the nature of these holsters being handmade in Mexico, some users will need to file behind the lever to ensure proper movement with no resistance.
