Retired swat - Safariland 6305 ALS/SLS Drop-Leg Glock Holster w/Quick-Release Leg Strap

Excellent balance between retention and draw. It's a solid holster at a good price. Expect to do a lot of draw practice to develop the muscle memory needed for speed if you are not familiar with the als/sls system. Once you got it down it's a quick draw. I'm never worried about a loose weapon with this holster.
