I ran across this holster accidentally and really like the way it works. Easily attaches to PALS systems and I'm currently running it on my Kifaru belt. The holster is adjustable internally to fit a variety of auto handgun slide lengths. I currently have a Sig P365XL but my buddy is running a SW Shield and it would easily accommodate a full size auto. I have no affiliation with the brand, just thought it might help someone out looking for a similar holster. And the best part is it's inexpensive!
