Safariland Model 6390: built for the Glock 20 Gens 1-4
Ask an armorer what to put a Glock 20 Gens 1-4 in and this series comes up fast. The Safariland Model 6390 with Level I retention is a standard-issue answer for a reason.
Why officers trust it
- Level I retention. One independent retention mechanism stand between the pistol and a gun grab — each defeated naturally by the wearer’s trained draw, and only by it.
- Mid-Ride carry. Puts the grip right at the natural sweep of the hand — the patrol standard.
- Uniform-matched finishes. Offered in STX Tactical to match agency uniform standards.
- ALS (Automatic Locking System). The pistol locks the moment it’s holstered, and a straight-back thumb release frees it in one natural drawing motion — nothing to pinch, rock, or think about.
Who carries it
Patrol officers, sheriff’s deputies, and campus and transit police carry this class of rig every shift; agencies standardize on it because armorers can service the hardware and every officer draws the same way.

Common questions
What does the retention level mean?
Safariland grades duty holsters by the number of independent locking mechanisms between the pistol and anyone who isn’t the officer wearing it. This model is Level I — one independent retention mechanism, each one released naturally during a trained draw.
Can I carry with a weapon light mounted?
No — this shell is cut for the Glock 20 Gens 1-4 without a rail-mounted light. If you run a light on duty, look for the light-bearing version of this series instead.
Is it available left-handed?
This listing is right hand-hand only as stocked. Ask the Network if you need the opposite-hand SKU — Safariland builds most models both ways.
About Safariland
Safariland has been building holsters since 1964, when Neale Perkins sewed the first ones in a Sierra Madre, California garage — and it went on to define modern duty retention, including the industry’s first Level III retention holster. 911 Network stocks the Safariland duty line deep — outfitting one officer or a whole agency, ask the Network and we’ll spec the right fit.
