Safariland Model 6378: built for the Smith & Wesson M&P 9
Retention you don’t think about is the point of the Safariland Model 6378. Holster the Smith & Wesson M&P 9 and it locks; draw it the way you trained and it’s simply there.
Why officers trust it
- Uniform-matched finishes. Offered in STX Plain, 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.
- SafariLaminate construction. Safariland’s duty laminate shrugs off impact, rain, and vehicle-frame abuse that ends leather rigs.
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 is right hand-hand only as stocked. Ask the Network if you need the opposite-hand SKU — Safariland builds most models both ways.
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.
