Everything I Learned from the Safariland Model 537 GLS Open Top Concealment Belt Slide Holster
The Safariland Model 537 GLS Open Top Concealment Belt Slide Holster is designed to offer a balance of security and accessible retention for concealed carry, featuring Safariland’s proprietary Grip Lock System (GLS). My search for a reliable OWB holster for my SIG Sauer P320 Compact intensified after a particularly frustrating range day where my previous, less secure holster allowed for too much movement and potential exposure. I needed something that would feel secure without adding excessive bulk, and crucially, provide a consistent draw without fumbling. While I considered a few other brands known for concealment holsters, the GLS system’s promise of an intuitive, finger-actuated release caught my eye as a potential game-changer for rapid deployment. My initial impression upon unboxing this Safariland model was one of practical sturdiness; it felt robust yet surprisingly lightweight.
Real-World Testing: Putting Safariland Model 537 GLS Open Top Concealment Belt Slide Holster to the Test
First Use Experience
My initial testing of the Safariland Model 537 GLS Open Top Concealment Belt Slide Holster took place primarily at my local indoor range and during everyday concealed carry rotations in an urban environment. I specifically chose to test its comfort and retention during extended periods of standing and moderate walking, simulating a typical workday. The holster performed admirably under these conditions, keeping the SIG Sauer P320 Compact securely in place without noticeable shifting.
The GLS (Grip Locking System) itself proved to be remarkably intuitive from the first draw. It engaged smoothly upon re-holstering and released with an almost subconscious sweep of the middle finger as I established my grip. This was a significant improvement over holsters requiring thumb breaks or awkward retention levers. I experienced no issues with dust or light moisture during my initial range sessions; the materials seemed resistant to minor environmental factors.
Extended Use & Reliability
After several weeks of consistent daily carry and numerous trips to the range, the Safariland Model 537 GLS Open Top Concealment Belt Slide Holster has held up exceptionally well. The exterior shows minimal signs of wear, mostly just superficial scuffs from being carried against clothing and occasional contact with my workshop bench. There’s been no noticeable stiffness in the GLS mechanism or the belt slide, and the retention remains as positive as day one.
Maintenance has been incredibly straightforward. A quick wipe-down with a damp cloth and occasional use of a soft brush to clear any dust or debris from the GLS mechanism has been sufficient. I haven’t experienced any significant performance degradation, which is a testament to its robust construction. Compared to some of the Kydex holsters I’ve used in the past, which could sometimes develop stress points or become a bit too rigid, this holster’s soft, flexible body offers a more comfortable and conforming fit against the body. It strikes a good balance, providing firm retention without the sharp edges that can sometimes plague harder plastic designs.
Breaking Down the Features of Safariland Model 537 GLS Open Top Concealment Belt Slide Holster
Specifications
The Safariland Model 537 GLS Open Top Concealment Belt Slide Holster is crafted from a durable, injection-molded polymer, providing a sturdy yet flexible housing for your firearm. Its primary feature is the Grip Locking System (GLS), which is designed to automatically secure the handgun when holstered and releases upon a standard shooting grip with the middle finger. This specific model is configured for the SIG Sauer P320 Carry and Compact, ensuring a precise fit. The holster attaches to your belt via a belt loop/snap width designed to accommodate standard 1.5-inch belts, which is a common size for concealed carry and duty belts. The fastener/closure type is explicitly the Grip Lock System.
These specifications translate directly into user benefits. The injection-molded polymer ensures durability and resistance to environmental factors. The GLS offers a highly secure retention mechanism that is also designed for rapid deployment, reducing the cognitive load during a stressful situation. The 1.5-inch belt loop width makes it versatile for use with most common carry belts, and the specific fit for the SIG Sauer P320 ensures optimal weapon retention and draw.
Performance & Functionality
In terms of core function, the Safariland Model 537 GLS Open Top Concealment Belt Slide Holster excels at its primary job: securely holding a SIG Sauer P320 Compact while allowing for a smooth, accessible draw. The GLS system is remarkably effective; the pistol feels completely secure when holstered, with no hint of it dislodging during everyday movement, even during brisk walks or bending. The draw is consistently clean, with the GLS releasing reliably as my firing grip is established.
The key strength of this holster lies in the intuitive GLS release. It’s a natural motion that doesn’t require conscious thought once practiced, which is crucial for concealed carry. A minor weakness, if one could call it that, is the inherent nature of an open-top, belt-slide design; it offers less protection against debris ingress than a fully enclosed holster might, but this is standard for its type. For its intended purpose of concealed carry with accessible retention, it performs at a very high level, meeting and often exceeding expectations for its price point.
Design & Ergonomics
The design of this Safariland holster prioritizes both security and user comfort. Its soft, flexible holster body is a standout feature, allowing the material to subtly conform to the wearer’s body shape, which significantly enhances comfort during long periods of wear. This flexibility also means it doesn’t dig into the hip as much as some rigid Kydex holsters can. The belt slide is designed to keep the holster snug against the body, minimizing printing under clothing.
Ergonomically, the GLS mechanism is well-placed and operates smoothly. The action of engaging the release with the middle finger feels natural and does not interfere with obtaining a full firing grip. The tension adjustment screw is accessible and allows for fine-tuning the fit of the firearm to the user’s preference, a small but appreciated detail. The black finish is standard and unobtrusive, ideal for concealment.
Durability & Maintenance
The injection-molded polymer construction suggests significant long-term durability for the Safariland Model 537 GLS Open Top Concealment Belt Slide Holster. Under normal concealed carry usage, I anticipate this holster will last for many years without significant degradation. The materials are resistant to cracking and abrasion, common issues with lesser holsters.
Maintenance is refreshingly simple. Regular cleaning involves wiping down the exterior and using a soft brush or compressed air to clear any debris from the GLS mechanism and inside the holster. There are no complex parts to maintain or lubricate, making it a low-fuss option. Potential failure points, common in other holster designs like adjustable retention screws that loosen or over-molded components that separate, appear to be minimized here due to the robust, one-piece molding and the integrated GLS design.
Accessories and Customization Options
The Safariland Model 537 GLS Open Top Concealment Belt Slide Holster comes as a complete unit, focusing on its core functionality rather than a suite of accessories. The primary customization option offered is the tension adjustment screw, allowing users to fine-tune how snugly the firearm fits within the holster. This is a crucial feature for ensuring both secure retention and a consistent draw.
While there are no additional included accessories like spare belt loops or different attachment methods (such as clips), the holster’s design is focused and effective for its intended purpose. It is designed to work with standard 1.5-inch belts, which are widely available. For users looking for alternative carry styles, Safariland offers other holster models with different mounting options, but this specific belt slide iteration is optimized for that particular attachment method.
