Safariland Model 637 ALS Concealment OWB Belt Holsters Review

My Experience with the Safariland Model 637 ALS Concealment OWB Belt Holsters: Here’s the Truth

After years of diverse field and workshop applications, I’ve learned that the right gear isn’t just about functionality; it’s about reliable integration into complex tasks. The Safariland Model 637 ALS Concealment OWB Belt Holsters presented itself as a promising solution for secure, accessible handgun carry in environments where quick deployment is crucial but safety paramount. This OWB (Outside the Waistband) holster boasts the reputable ALS (Automatic Locking System) retention, designed to offer a balance of security and ease of access. My search for a dependable holster that could handle the demands of both professional requirements and personal readiness led me to this particular model. It’s a step up from basic friction-fit designs, promising a more robust connection between the user and their firearm.

My journey to this specific holster began with a need for something that offered more positive retention than my previous setups. Relying on a standard duty holster for certain off-duty scenarios felt overkill, and concealed options often compromised immediate accessibility. The thought of a more streamlined, yet secure, system for everyday carry or specific professional contexts became a priority. I considered a few other well-known brands, but the reputation of Safariland for robust retention systems, particularly the ALS, made it a compelling choice. My initial impression upon handling the Model 637 was one of solid, no-nonsense construction. It felt substantial without being overly bulky, suggesting it could perform as advertised.

Real-World Testing: Putting Safariland Model 637 ALS Concealment OWB Belt Holsters to the Test

First Use Experience

My initial testing focused on the primary function: securing and drawing a Glock pistol. I utilized this setup during several extended periods at a controlled outdoor range and during routine training exercises that involved dynamic movement. The holster performed admirably under typical conditions, maintaining a firm grip on the firearm even during swift movements and simulated defensive drills. The ALS locking mechanism immediately felt secure; there was no accidental disengagement during physical activity.

The transition from holstered firearm to ready-to-fire was remarkably smooth. The thumb release for the ALS is instinctively placed, and with a little practice, the draw stroke became fluid and natural. While I didn’t intentionally expose it to extreme elements, light dust and the general grime of outdoor training environments did not seem to affect its performance. Its low-profile design meant it sat comfortably against the hip, allowing for a relatively unhindered range of motion.

Extended Use & Reliability

Over several months of consistent use, this Safariland holster has proven to be a reliable workhorse. I’ve carried it during extended range days, personal defense practice sessions, and even for periods of administrative detail where the firearm needed to be secured but readily accessible. The holster’s materials have shown minimal wear; the plastic retains its form, and there are no signs of stress or cracking despite frequent weapon insertion and extraction.

Maintenance has been minimal, typically involving a quick wipe-down with a damp cloth and occasional light lubrication on the ALS mechanism. Unlike some fabric holsters that can retain moisture or debris, the rigid polymer construction of this model makes it incredibly easy to keep clean. Compared to other OWB holsters I’ve used in the past, this one maintains its rigidity and retention capabilities without loosening over time, a common issue with lesser-quality designs.

Breaking Down the Features of Safariland Model 637 ALS Concealment OWB Belt Holsters

Specifications

The Safariland Model 637 ALS Concealment OWB Belt Holsters are constructed from a durable, proprietary polymer blend designed to withstand the rigors of daily use. This material offers a good balance of rigidity for secure retention and a slightly flexible body that allows it to conform somewhat to the wearer’s hip for a more comfortable fit. The holster features the ALS (Automatic Locking System), which uses a thumb-operated lever to secure the firearm.

This system ensures that the weapon remains firmly in place until the release is intentionally activated. The holster also includes a belt loop system designed to accommodate standard gun belts, providing stable positioning on the hip. Its design is intentionally low-profile, aiming for a higher and tighter carry position to aid in concealment without sacrificing accessibility.

Performance & Functionality

The primary function of this holster – retaining and presenting a firearm – is executed exceptionally well. The ALS system provides a very secure hold, instilling confidence that the weapon will not inadvertently fall out. The draw stroke is swift and predictable once the user becomes accustomed to the thumb release.

• Retention: Outstanding. The ALS mechanism provides a positive lock that is incredibly reliable.
• Draw Speed: Very good. While not a duty-level speed draw holster, it’s surprisingly quick for a retention-style OWB.
• Fit: Generally good, with an adjustable tension screw allowing for fine-tuning of the firearm’s fit within the holster. This ensures a snug fit that prevents rattling while still allowing for a smooth draw.

Design & Ergonomics

The design prioritizes both security and comfort for an OWB carry option. Its low-profile construction helps reduce printing, making it more amenable to concealed carry than bulkier tactical holsters. The body of the holster has a slight contour to accommodate the wearer’s hip, which enhances comfort during extended wear.

• Materials: The high-grade polymer feels robust and has a slightly textured finish that offers a good grip.
• Comfort: It sits higher on the waist than many other OWB holsters, which can aid comfort and concealability for some users. The soft, flexible body helps it mold to the wearer, reducing pressure points.
• Thumb Release: The ALS thumb lever is well-placed and designed for an intuitive operation. It’s easily accessible with the thumb of the shooting hand during the draw stroke.

Durability & Maintenance

Based on my experience, the Safariland Model 637 ALS Concealment OWB Belt Holsters are built to last. The polymer material is resistant to impacts and environmental factors. Its rigid construction means it’s unlikely to deform or lose its shape over time, which is a common issue with softer materials.

• Wear and Tear: Minimal signs of wear after several months of regular use. The finish remains intact, and the locking mechanism functions as new.
• Cleaning: Extremely easy to clean with soap and water or a damp cloth. Debris does not get easily trapped in the holster’s construction.
• Longevity: This holster feels like it will serve reliably for many years, even with frequent use.

Accessories and Customization Options

The primary feature here is the integrated ALS locking system, which is Safariland’s proprietary retention technology. This holster is specifically designed to accommodate Glock firearms, providing a precise fit.

• Belt Attachment: It typically comes with a belt loop that fits belts up to 1.75 inches wide, offering a secure attachment. Some variations may be available with different mounting options, such as a paddle.
• Customization: While the holster itself is not extensively customizable in terms of color or finish (often available in plain black), the tension adjustment screw allows for fine-tuning the firearm’s fit.

This holster is an excellent choice for individuals who prioritize secure firearm retention combined with accessible carry.

I would also recommend a good quality, sturdy gun belt to maximize the stability and comfort of carrying this holster.
