The Science Behind Security: Understanding the Automatic Locking System (ALS®)

At the core of the Safariland 6378's exceptional performance is the revolutionary Automatic Locking System (ALS®). This patented technology is a hallmark of Safariland's commitment to innovation and safety. So, what exactly is ALS® and how does it work to enhance your firearm security?

When you holster your firearm, the ALS® system automatically engages, securely locking the weapon in place. This isn't just passive friction; it's a positive, active retention device that provides an additional layer of security beyond what many traditional holsters offer. The locking mechanism acts on the ejection port of the firearm, ensuring a tight, secure fit that prevents the weapon from being easily snatched or falling out, even if you're running, jumping, or engaged in a struggle.

Despite its robust security, the ALS® system is designed for an incredibly intuitive and rapid draw. To release the firearm, you simply use your thumb to disengage a small lever located on the inside of the holster as you acquire your grip. This natural thumb-swipe motion integrates seamlessly into the drawing process, allowing for an incredibly fast and fluid presentation. There's no complex sequence of movements, no awkward pushing or pulling—just a simple, instinctive action that becomes second nature with minimal practice. This blend of automatic security upon holstering and a natural, swift release mechanism is what makes ALS® holsters a top choice for professionals worldwide.

Key advantages of the ALS® system include:

• Instantaneous Retention: Locks the firearm immediately upon holstering.
• Enhanced Safety: Prevents accidental discharge during holstering or unholstering due to secure retention.
• Superior Security: Significant resistance to takeaways, providing peace of mind in dynamic environments.
• Natural Draw Stroke: Thumb-activated release integrates seamlessly with a standard shooting grip.
• Reliability: A robust mechanical system that performs consistently in various conditions.

Built to Endure: The Strength of SafariLaminate™ Construction

Durability is non-negotiable for a holster, especially one intended for daily use in demanding conditions. The Safariland 6378 utilizes Safariland's proprietary SafariLaminate™ construction, a meticulously engineered material that sets it apart from many other holster materials.

SafariLaminate™ is not just a single material but a specialized thermal-molded laminate designed for extreme resilience. It offers exceptional strength and rigidity on the outside, resisting impacts, abrasions, and the wear and tear of daily use. This robust exterior ensures the holster maintains its form and function over extended periods, even when subjected to harsh environmental factors like moisture, temperature fluctuations, and exposure to cleaning solvents. The structural integrity provided by SafariLaminate™ contributes significantly to the holster's longevity and reliable performance, making it a truly long-term investment.

Complementing the rugged exterior, the interior of the Safariland 6378 features a soft, protective SafariSuede™ lining. This inner layer serves a crucial purpose: safeguarding your firearm's delicate finish. Over time, repeated holstering and drawing can cause wear marks on a firearm, especially around the front sight and slide. SafariSuede™ acts as a buffer, providing a gentle contact surface that minimizes friction and protects your firearm from scratches and abrasions. This thoughtful internal design ensures your Glock 20 or Glock 21, along with its Surefire X300, remains in pristine condition, preserving its aesthetic and functional integrity.

Versatility in Carry: Paddle Mount and Standard Belt Loop Options

The Safariland 6378 is celebrated not only for its advanced retention system and durable construction but also for its exceptional versatility in carry options. Recognizing that users have different preferences and needs for how they wear their holster, the Model 6378 comes standard with both a convenient paddle attachment and a traditional standard belt loop.

The Paddle Attachment:
The included paddle attachment offers unparalleled convenience. It allows for quick donning and doffing of the holster without needing to remove your belt. This is particularly advantageous for individuals who frequently transition between different activities or environments. The paddle features a robust design that hooks over the waistband and secures firmly against the body, offering surprising stability for an OWB setup. It's often favored for:

• Quick Changes: Easily put on or take off the holster as needed.
• Comfort: The contoured design fits snugly against the body, distributing weight comfortably.
• Ease of Use: Simple and intuitive to attach and remove.
• Range Use: Ideal for range sessions where you might want to quickly holster and unholster for drills.

The Standard Belt Loop:
For those who prioritize maximum stability and a more fixed carry position, the standard belt loop is the preferred option. This attachment slides directly onto your belt, providing a secure and low-profile fit. The belt loop ensures the holster remains tightly against your body, reducing movement and enhancing retention, especially during vigorous activity. It’s typically chosen for:

• Enhanced Stability: Keeps the holster firmly in place, minimizing movement.
• Duty/Long-Term Wear: Offers a secure platform for extended periods of carry.
• Discreet Profile: Often provides a slightly closer ride to the body compared to some paddle designs, aiding in concealment under a cover garment.
• Consistent Positioning: Ensures your firearm is always in the exact same spot for reliable draw practice.

The inclusion of both options with the Safariland 6378 provides genuine adaptability, allowing you to choose the carry method that best suits your activity, attire, and personal preference on any given day. This dual-attachment capability makes the holster as functional as it is versatile.

Precision Fit: Glock 20/21 with Surefire X300 Compatibility

One of the critical aspects of an effective holster is its precise fit for the intended firearm and any attached accessories. The Safariland 6378 is meticulously molded for Glock 20 and Glock 21 pistols, ensuring a perfect, snug fit that optimizes retention and facilitates a smooth draw. What truly sets this specific model apart is its dedicated compatibility with the Surefire X300 weapon-mounted light.

Modern tactical environments and personal defense scenarios often necessitate the use of a weapon light for target identification in low-light conditions. The Surefire X300 is an industry-standard, highly reliable, and widely adopted weapon light known for its powerful illumination. The Safariland 6378 acknowledges this critical accessory by designing the holster to accommodate the X300 seamlessly. This means:

• No Compromise on Light Use: You don't have to choose between carrying with a light or having a secure holster.
• Optimized Retention with Light: The ALS® system interacts perfectly with the firearm and light combination, ensuring secure retention of the complete setup.
• Smooth Draw with Light: The holster's interior is shaped to allow for an unhindered draw even with the added bulk of the X300.
• Protection for Your Light: The SafariLaminate™ construction also provides a protective shell for your valuable Surefire X300, shielding it from impacts and environmental damage.

This dedicated compatibility eliminates the guesswork and frustration often associated with finding a holster for a light-bearing firearm. It ensures that both your Glock 20/21 and your Surefire X300 are securely housed and readily accessible when you need them most.
