Safariland Model 6378: built for the Glock 34 Gens 1-4
Retention you don’t think about is the point of the Safariland Model 6378. Holster the Glock 34 Gens 1-4 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.
- 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, STX Tactical 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
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.
Can I carry with a weapon light mounted?
No — this shell is cut for the Glock 34 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.
