ALS Nub Mod Install Instructions for all Level I holsters
1. Lay holster on flat surface, or hold it in your weak hand. This will be pretty easy. If highly motivated, hang from a pull-up bar by your toes and set holster on floor.
Holster types and fit:
The Nub Mod will not work with the Safariland ALS Guard. The Nub Mod will not work with the older style ALS holsters that have the 'step' into the holster body without a fair amount of work.
Common Sense Warning:
If you are worried about someone taking your gun from you this would make that easier. Obviously anything that makes it easier for you will make it easier for your enemy. If you simply want to keep your gun in your holster while doing whatever it is you do, and still be able to get it out fast without going through multiple levels of retention, the ALS only and Nub Mod are probably just what you are after.
