Safariland Model 6378RDS: built for the Glock 17 MOS
Retention you don’t think about is the point of the Safariland Model 6378RDS. Holster the Glock 17 MOS and it locks; draw it the way you trained and it’s simply there.
Why officers trust it
- 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.
- Light-bearing fit. Molded for the Glock 17 MOS with its weapon light mounted, so the pistol rides tight with the light in place.
- Optic-ready cut. Clears a slide-mounted red dot without giving up the locking hardware.
- SafariLaminate construction. Safariland’s duty laminate shrugs off impact, rain, and vehicle-frame abuse that ends leather rigs.
- Uniform-matched finishes. Offered in STX Plain to match agency uniform standards.
Who carries it
Detectives, plainclothes assignments, and off-duty carriers run this class of holster where a duty rig would print or snag.

Common questions
Is it available left-handed?
This listing covers left hand and right hand configurations — pick your hand in the options above before adding to cart.
Does it need a break-in period?
No. The shell is molded to the firearm, so retention is set by the locking hardware rather than friction — fit is correct out of the box.
Is this a duty or concealment holster?
Concealment — check the ride and belt attachment in the specs to confirm it matches how you intend to wear it.
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.
