Safariland 6378Rds832131 Als Black Fits Glock 17 Mos Gen5 Compatible W/ Surefire X300U Right Hand

The Safariland 6378RDS ALS holster is a duty-grade right-hand holster engineered for shooters running a Glock 17 MOS Gen5 with a SureFire X300U weapon light. Built around Safariland's proven ALS (Automatic Locking System) retention, this holster locks onto your pistol's trigger guard the moment it's holstered—no thumb break to manipulate, just secure, instant retention. It's the kind of holster you see on duty belts, but it works equally well for serious sport shooters, armed citizens, and anyone who values a weapon-mounted light and wants foolproof retention without fiddling.

Safariland's ALS system is field-proven across thousands of law enforcement agencies, and for good reason. It provides positive retention against unintentional draws while allowing a smooth, natural draw stroke when you need it. The holster is molded to fit your specific optics configuration—Glock 17 MOS with the X300U—so you get a precise, snug fit right out of the box. Whether you're training at the range, carrying professionally, or running dynamic drills, ALS retention means one less variable to think about.

The 6378RDS is built tough. Its durable polymer construction resists wear and environmental abuse, and the black finish blends seamlessly with tactical and duty gear. This is a holster that prioritizes security and reliability over exotic materials or flash—exactly what you want when your draw matters.
