Safariland 6354Rdso2832132Ms19 Als Black Hardshell Stx Fits Glock 19 Mos Compatible W/ Surefire X300U

The Safariland 6354RDSo ALS (Automatic Locking System) hardshell holster is built for serious shooters who run a Glock 19 MOS platform with a mounted light. This is a duty-grade holster engineered for fast, reliable draws and retention—the kind of gear you trust in high-stress situations. The 6354RDSo is specifically configured to work seamlessly with the SureFire X300U, so your light rides in the right position without compromise, and the holster secures your pistol with Safariland's proven automatic locking mechanism.

Safariland's STX material is a durable polymer blend that has earned respect across law enforcement and tactical communities for its combination of durability and weather resistance. The rigid, black finish resists wear and UV fade, and the hardshell construction protects your gun from impacts and snagging while maintaining a consistent draw stroke every single time. The RDS footprint accommodates red dot sight cuts, giving you the optical advantage without re-holstering hassles.

Whether you're carrying for duty, competition, home defense, or serious field work, the 6354RDSo delivers the retention and accessibility professionals demand. The ALS release is instinctive—one thumb motion and you're ready. This is a holster that doesn't make compromises between security and speed, and it won't leave you second-guessing your setup in the moment that counts.

Frequently Asked Questions

Will this holster fit a Glock 19 Gen 4 or Gen 5 without the MOS cut?

No. The 6354RDSo is specifically molded for the Glock 19 MOS platform with its integral mounting rails for optics. Compatibility is limited to that frame variant.

Can I use this holster without the SureFire X300U light?

This holster is purpose-built for the X300U mounted on an MOS-cut Glock 19. Using it without that light configuration will affect retention and fit. We recommend running the intended setup.

What does the ALS (Automatic Locking System) do?

The ALS mechanism automatically locks your pistol in the holster the instant it's seated—no thumb break or strap needed. A single thumb motion on the release activates the draw. It's fast, reliable, and doesn't require you to manage secondary retention steps.

Is this an IWB or OWB holster?

The 6354RDSo is an outside-the-waistband (OWB) duty-style holster designed for strong-side carry, common in law enforcement and tactical loadouts.
