Safariland 6378Rds2222131 Als Black Fits S&W M&P 2.0/C.O.R.E. Compatible W/ Surefire X300U Right Hand

The Safariland 6378RDS is a duty-grade holster built for shooters running an S&W M&P 2.0 or M&P C.O.R.E. with a SureFire X300U mounted on the rail. This right-hand draw holster combines two proven Safariland retention systems—the ALS (Automatic Locking System) and SLS (Self Locking System)—to give you fast, secure access when you need it and reliable retention when you don't. Whether you're training at the range, running low-light drills, or carrying professionally, the 6378RDS delivers the kind of dependable performance that's made Safariland a go-to for law enforcement and serious civilians alike.

The ALS mechanism locks your pistol into place the moment it's holstered, using nothing but the gun's shape—no buttons to fumble in a tense moment. That speed and simplicity have made it standard across thousands of duty rigs. The dual-retention design means you get both passive security and active control, so your gun stays put during movement or physical activity while still coming free smoothly when you draw. The holster is molded specifically for the M&P 2.0 platform, so fit is tight and indexing is consistent.

Built in black with Safariland's durable polymer construction, the 6378RDS handles the wear and tear of serious use. The design accommodates the SureFire X300U light, a full-size weapon light that's become the standard for duty and defensive setups. This is a holster that doesn't demand babying—it's meant to work in real conditions, ride on a duty belt, and earn its keep over years of training and carry.

Frequently Asked Questions

What's the difference between ALS and SLS retention?

The ALS (Automatic Locking System) engages passively the instant your pistol enters the holster—it uses the gun's shape to lock it in place without any button press or manual action. The SLS (Self Locking System) adds an extra layer of security on top of the ALS. Together, they provide both rapid deployment and dependable retention across a wide range of movement and activity.

Will this holster fit my S&W M&P 2.0 with a mounted light?

Yes—this holster is specifically molded to accommodate the S&W M&P 2.0 and M&P C.O.R.E. when fitted with a SureFire X300U light. The holster's internal geometry accounts for the light's profile, so fit is snug and proper indexing is maintained.

Is this a right-hand or left-hand holster?

This is a right-hand draw holster, meaning it's configured for shooters who draw with their right hand and carry on the right side of their body or belt.

Who uses holsters like the 6378RDS?

The 6378RDS is built for duty carry, professional security work, and serious civilian training. Law enforcement agencies and armed professionals have made Safariland's ALS-equipped holsters the standard in those roles, and the design is equally suited to dedicated shooters who want that same level of reliability and retention.
