SureFire X400U Weapon Light: The Ultimate Handgun Illumination and Targeting Solution

When it comes to enhancing the capabilities of your rail-equipped handgun, discerning users consistently seek solutions that offer uncompromising performance, unwavering reliability, and superior target engagement. The SureFire X400UAGN X400U Weapon Light stands as a pinnacle in this category, expertly blending potent illumination with a highly visible green laser for rapid, precise target acquisition in any lighting condition. This advanced accessory is not just a light; it's a critical component designed to elevate situational awareness, improve accuracy, and provide a decisive edge for responsible gun owners, tactical professionals, and anyone prioritizing effective self-defense.

Why is a Weapon Light and Laser Combination Essential for Your Handgun?

For anyone considering a serious upgrade to their handgun, the question often arises: "Why do I need a weapon light, and is a laser truly beneficial?" The answer lies in the multifaceted challenges of low-light engagements and the critical need for rapid, confident target identification. Imagine a home defense scenario: a bump in the night, a darkened room. Without proper illumination, distinguishing a threat from an innocent family member becomes impossible. A powerful weapon light cuts through the darkness, allowing for positive target identification, which is paramount before making any decision.

Adding a laser, particularly a high-visibility green laser like that on the SureFire X400UAGN, further amplifies your capability. It provides an immediate, intuitive aiming point, drastically reducing the time it takes to get on target, especially in dynamic, stressful situations where precise sight alignment might be challenging. For tactical training, competitive shooting, or real-world defensive applications, the combination of light and laser means faster follow-up shots, improved accuracy under pressure, and superior situational awareness. This integrated system streamlines your response, allowing you to focus on the threat rather than struggling with inadequate visibility.

Unmatched Illumination: 1000 Lumens of Pure Power

The SureFire X400UAGN is engineered to deliver an overwhelming flood of light precisely when you need it most. At its core is a recoil-proof LED emitter, paired with a sophisticated TIR (Total Internal Reflection) lens. This proprietary SureFire technology focuses a staggering 1000 lumens of output into a meticulously crafted beam. What does this mean for the user?

• Smooth, Far-Reaching Beam: Unlike lights with hot spots and rings, the X400UAGN produces a clean, consistent beam that minimizes visual distractions and maximizes effective illumination.
• Large Central Spot: This central "spot" is intensely bright, ensuring that your target is brilliantly lit, allowing for clear identification of details even at a distance.
• Optimal for Close to Medium Engagements: With an impressive range of 213 meters (approximately 233 yards), this light is perfectly suited for typical self-defense distances found in homes, urban environments, or tactical training facilities. It provides ample reach without unnecessary spill that could compromise your position.

This level of illumination is critical for positive target identification, assessing potential threats, and navigating dimly lit environments with confidence. Whether you're clearing a room or engaging targets at the range, the X400UAGN ensures you have the visual information needed to make informed decisions.

Precision Targeting with a High-Visibility Green Laser

Beyond its formidable lighting capabilities, the SureFire X400UAGN integrates a powerful 5-milliwatt green laser, operating at a wavelength of 515 nanometers. Why green? The human eye is significantly more sensitive to the green spectrum than red, making green lasers appear substantially brighter and more visible, even in daylight or against busy backgrounds.

• Rapid Target Acquisition: The green laser provides an instantaneous point of aim, allowing for lightning-fast target acquisition without the need to align traditional iron sights or a red dot optic. This is invaluable in high-stress scenarios where every fraction of a second counts.
• Enhanced Accuracy: By projecting a visible dot onto your target, the laser offers immediate feedback on your point of aim, assisting in precise shot placement. This is particularly beneficial for users who may struggle with sight picture or for unconventional shooting positions where aligning traditional sights is difficult.
• Training Aid: For training purposes, the laser offers a clear visual representation of trigger control and muzzle movement, allowing users to identify and correct bad habits, leading to improved fundamental shooting skills.

The combination of SureFire's legendary white light output with this vivid green laser creates a synergistic system, providing both superior visibility and unparalleled aiming speed.

Engineered for Durability: Built to Withstand the Toughest Conditions

SureFire has built its reputation on manufacturing rugged, dependable products that perform under the most extreme conditions. The X400UAGN is no exception. Its construction reflects an unwavering commitment to durability and longevity.

• Aerospace-Grade Aluminum Body: The body of the X400UAGN is crafted from lightweight yet incredibly strong aerospace-grade aluminum. This material choice provides exceptional resistance to impact, abrasion, and daily wear and tear.
• Hard Anodized Finish: The black anodized finish isn't just for aesthetics; it provides a tough, corrosion-resistant surface that protects the internal components from the elements and extends the lifespan of the unit.
• Recoil and Weatherproof Design: This weapon light is designed from the ground up to be recoil-proof, meaning it can withstand the repeated shock and vibration of firearm discharge without compromising performance or internal components. Furthermore, its weatherproof construction ensures reliable operation in rain, humidity, or dusty environments, making it a dependable choice for any mission or application. At 4.90 oz and 3.60" OAL, it strikes an optimal balance between robustness and low profile on your firearm.

This robust construction ensures that the SureFire X400UAGN is not merely an accessory but a resilient tool that will stand up to the rigors of tactical use, extensive training, or demanding defensive situations.

Seamless Integration and User-Friendly Operation

Compatibility and ease of use are paramount for any firearm accessory. The SureFire X400UAGN excels in both areas, ensuring that it integrates effortlessly with a wide range of popular handguns and offers intuitive control.

• Versatile Mounting System: Designed to fit virtually any rail-equipped pistol, the X400U features a highly adaptable mounting system. It quickly and securely attaches to both Picatinny (MIL-STD-1913) and Weaver rails, as well as the proprietary rails found on Glock pistols. This broad compatibility makes it an ideal choice for a diverse arsenal, from compact defensive pistols to full-size duty weapons.
• Ambidextrous Switching: Understanding that shooters operate with varying preferences and in dynamic environments, SureFire has equipped the X400UAGN with an ambidextrous push/toggle switch. This intuitive design allows both left-handed and right-handed users to activate the light and laser with equal ease, ensuring seamless operation regardless of the shooting hand or grip style. Momentary-on activation is achieved by pressing the switch, while constant-on is engaged by toggling it.
• Battery Efficiency: Powered by CR123A batteries, the X400UAGN boasts a runtime of 1+ hours on a single set. This ensures ample operational time for training sessions or defensive scenarios, with the added benefit of readily available battery replacements.
