Safariland 6304RDS ALS/SLS Drop Leg Glock Holster Review

Hands-On with the Safariland 6304RDS ALS/SLS Drop Leg Glock Holster

After years of relying on trusted, often no-frills gear for critical applications, the advent of red dot sights on handguns presented a new challenge: finding a holster that could securely retain a modern pistol without compromising access. My work environments—from dusty field sites to well-lit workshop benches—demand gear that is both robust and rapidly deployable. This need led me to the Safariland 6304RDS ALS/SLS Drop Leg Glock Holster, a specialized piece of kit designed to accommodate optics-mounted firearms. It promised a blend of advanced retention and user-friendly operation, a combination I rarely found in older designs.

I’d been fielding a Glock equipped with a popular red dot optic, and my existing holsters, while reliable for iron sights, simply didn’t fit or compromised the optic’s integrity. I considered a few Kydex alternatives, but the thought of an optic-retaining mechanism that could potentially scratch the lens or be overly complex deterred me. My immediate impression upon unboxing the Safariland was one of serious engineering; the SafariLaminate construction felt substantial, and the combination of the ALS and SLS retention systems looked promising. It offered a tangible sense of security, a welcome departure from the sometimes flimsy feel of certain polymer holsters.

Real-World Testing: Putting Safariland 6304RDS ALS/SLS Drop Leg Glock Holster to the Test

First Use Experience

My initial tests involved integrating this drop leg holster into my regular operational routines, which often involve dynamic movement and rapid transitions between low-light and bright conditions. I focused on drawing and re-holstering the pistol repeatedly while on a shooting range, simulating tactical movement scenarios, and even wearing it during extended periods of light physical activity to gauge comfort. The ALS (Automatic Locking System) and SLS (Self Locking System) took a few repetitions to become second nature, but the process of disengaging the ALS thumb lever and rotating the SLS hood was surprisingly fluid once I established the muscle memory.

The holster performed admirably in varying environmental conditions, from the grit of a dry shooting range to the humidity of an outdoor training session. Dust and minor moisture didn’t seem to impede the locking mechanisms or the draw stroke, a testament to the robust design. The adjustable vertical leg strap and silicone strips proved effective in keeping the holster stable against my leg, minimizing excessive movement during rapid maneuvers. There were no immediate surprises, just a steady confirmation that this holster was built for purpose.

Extended Use & Reliability

Over several months, this Safariland holster has become a constant companion for my optic-equipped Glock. It has seen countless draws and re-holsters, been subjected to the occasional bump and scrape against doorways and equipment, and has maintained its integrity. The SafariLaminate thermoformed construction shows minimal signs of wear; there are no significant scuffs on the exterior, and the internal suede lining remains intact, still protecting the firearm’s finish.

Maintenance has been straightforward, primarily involving occasional cleaning with a damp cloth and ensuring the retention mechanisms are free of debris. The Cordura nylon wrap finish has also held up well, showing no signs of fraying or wear. Compared to previous experiences with less robust holsters that developed stiffness or became loose over time, this unit feels as solid as the day I first put it on. It has certainly outperformed budget Kydex options I’ve used in the past, particularly in maintaining consistent retention and smooth draw characteristics.

Breaking Down the Features of Safariland 6304RDS ALS/SLS Drop Leg Glock Holster

Specifications

The Safariland 6304RDS ALS/SLS Drop Leg Glock Holster is constructed from SafariLaminate, a durable material designed for the rigors of tactical use. It is specifically designed for Glock firearms equipped with mounted red dot optics. The holster features a dual retention system: the ALS (Automatic Locking System) that secures the weapon in all directions upon holstering and is released by a thumb lever for a straight draw, and the SLS (Self Locking System), a rotating hood that adds a secondary layer of security. The drop leg design incorporates a quick-release double leg strap system for comfortable and low-profile carry, complete with silicone strips for enhanced grip. Internally, the holster is suede lined to prevent scratching of the firearm’s finish and optics. The Cordura nylon wrap finish also serves to reduce its infrared (IR) signature, a critical feature for tactical applications.

These specifications translate directly into user benefits. The SafariLaminate offers robust protection against the elements and physical impact. The combination of ALS and SLS provides exceptional weapon retention, crucial for preventing accidental disarms or unauthorized access. The leg strap design ensures the holster remains stable, a significant improvement over single-strap designs that can shift. Finally, the suede lining and IR-reducing finish demonstrate a thoughtful approach to protecting both the firearm and its operator.

Performance & Functionality

The primary function of the Safariland 6304RDS ALS/SLS Drop Leg Glock Holster is to securely retain a red dot-equipped pistol while allowing for a rapid, unobstructed draw. It excels in this regard, offering a level of security that instills confidence in demanding situations. The ALS mechanism, once mastered, allows for a surprisingly quick disengagement, enabling a straight-up draw without any canting or twisting. The SLS hood, while requiring an extra step, adds a significant security blanket, especially during high-movement activities.

Its main strength lies in its dual retention system, which is exceptionally secure without being overly cumbersome. However, the learning curve for operating both the ALS and SLS simultaneously might be a minor drawback for absolute beginners. It comfortably meets and often exceeds expectations for a tactical-grade holster, especially for those prioritizing optic compatibility and robust retention.

Design & Ergonomics

The design of this Safariland holster is clearly driven by functionality and durability. The SafariLaminate material feels solid and substantial, giving the impression of a product built to last. The thermoformed construction ensures a precise fit for the intended Glock models, cradling the firearm securely. The drop leg configuration distributes the weight evenly and places the firearm in a natural position for drawing, especially when wearing body armor or tactical vests.

Ergonomically, the placement of the ALS thumb release is intuitive and falls naturally under the thumb of a standard shooting grip. The SLS rotating hood also operates smoothly, though it requires a deliberate thumb action. The double leg strap system, with its silicone strips, provides excellent stability without being overly restrictive. The overall feel is one of a well-engineered piece of equipment designed for professional use.

Durability & Maintenance

Based on my extended testing, the Safariland 6304RDS ALS/SLS Drop Leg Glock Holster appears to be exceptionally durable. The SafariLaminate is resistant to abrasions and impacts, and the Cordura nylon wrap provides an additional layer of protection. I have not encountered any cracks, stiffness, or loosening of components, even after consistent use in varying conditions.

Maintenance is minimal, requiring little more than wiping down the exterior and ensuring the retention mechanisms are free from dirt or grit. The suede lining is forgiving and can be gently cleaned if necessary. There are no obvious failure points to be concerned about under normal operational stress, making it a reliable choice for long-term use.

Accessories and Customization Options

The Safariland 6304RDS ALS/SLS Drop Leg Glock Holster comes as a complete unit, focusing on its core function rather than extensive customization. The primary “accessory” is, of course, the firearm it is designed to carry, specifically Glock models fitted with red dot sights. The holster itself is designed to accommodate these optics without issue. The quick-release double leg strap system is adjustable, allowing users to fine-tune the fit for their leg size and comfort.

While there are no user-replaceable parts in the traditional sense, the holster’s robust construction means such replacements are unlikely to be needed often. Compatibility with standard leg strap systems or other mounting platforms is not its focus; it is a purpose-built drop leg solution. The integrated design ensures all components work cohesively.

Pros and Cons of Safariland 6304RDS ALS/SLS Drop Leg Glock Holster

Who Should Buy Safariland 6304RDS ALS/SLS Drop Leg Glock Holster?

This holster is an excellent choice for law enforcement officers, military personnel, security professionals, and serious competition shooters who carry a red dot-equipped Glock pistol and require a high level of weapon retention and rapid access. It is particularly well-suited for those who operate in dynamic environments where weapon security is paramount, such as tactical training, high-threat response, or competitive shooting disciplines that mimic real-world scenarios.
