The HiViz FASTDOT H3 For Glock MOS 9/40 Tritium/Fiber Optic Night Sights Made a Bold First Impression
The HiViz FASTDOT H3 For Glock MOS 9/40 Tritium/Fiber Optic Night Sights promises enhanced visibility in all lighting conditions for Glock MOS pistols chambered in 9mm, .40 S&W, and .357 Sig. Blending tritium with fiber optic technology, these sights aim to provide a 24-hour aiming solution for personal defense, law enforcement, and military applications. This sight set offers a red fiber optic front sight coupled with a green tritium rear sight, maintaining factory sight height.
My aging eyes were finding it increasingly difficult to acquire a clear sight picture, especially in low-light situations during training drills. I needed a reliable, high-visibility sight system for my Glock 19 MOS that could perform flawlessly both day and night. The promise of HiViz’s combined tritium and fiber optic technology piqued my interest.
The HiViz FASTDOT H3 arrived in a no-frills package, but the sights themselves immediately struck me as robust and well-made. The steel construction felt solid in my hand, and the contrasting red and green colors were vibrant. I immediately noticed the brightness of the fiber optic front sight.
I considered Trijicon HD XR sights and Ameriglo Defoor sights, both reputable options known for their durability and visibility. However, the HiViz sights offered a unique combination of day and night visibility at a more accessible price point, appealing to my practical side. My initial impression was one of cautious optimism – excited by the potential but eager to see how they performed in real-world scenarios.
Real-World Testing: Putting HiViz FASTDOT H3 For Glock MOS 9/40 Tritium/Fiber Optic Night Sights to the Test
First Use Experience
My first range trip with the HiViz FASTDOT H3 was at my local outdoor range, a place I frequent weekly for training. I tested the sights in varying light conditions, from bright daylight to the fading light of dusk. The red fiber optic front sight was incredibly easy to acquire in daylight, drawing my eye quickly to the target.
As the sun began to set, the tritium inserts in the rear sight started to glow, providing a clear reference point for alignment. There was a bit of a learning curve in transitioning between the bright daylight fiber optic and the low-light tritium. However, after a few magazines, I found my rhythm.
The only initial issue I encountered was the front sight seemed slightly too bright in direct sunlight, causing a small amount of bloom that made precision shots a tad challenging.
Extended Use & Reliability
After several months of consistent use, including weekly range sessions and a defensive pistol course, the HiViz FASTDOT H3 sights have held up remarkably well. The steel construction has proven its durability, with no signs of bending, chipping, or significant wear on the finish. Cleaning is straightforward; a simple wipe-down with a gun cleaning cloth after each range session keeps them in top condition.
Compared to my previous experience with basic Glock factory sights, the HiViz sights are a game-changer. They have noticeably improved my speed and accuracy, especially in less-than-ideal lighting situations. These sights simply outperform factory sights in any environment other than perfectly lit outdoor ranges.
Breaking Down the Features of HiViz FASTDOT H3 For Glock MOS 9/40 Tritium/Fiber Optic Night Sights
Specifications
The HiViz FASTDOT H3 is designed specifically for Glock MOS models chambered in 9mm, .40 S&W, and .357 Sig. This ensures a proper fit and function without requiring modification to your firearm.
The sight set maintains a factory sight height, meaning it won’t significantly alter the point of impact at various distances. This allows for an easy transition from your factory sights without a need to re-learn your hold-over.
The front sight features a red fiber optic insert for enhanced visibility in daylight. This bright, easy-to-see dot is crucial for fast target acquisition in well-lit environments.
The rear sight has green tritium inserts that glow in low-light and no-light conditions. This allows for accurate aiming even when minimal light is available.
Constructed from steel, the HiViz FASTDOT H3 sight set is built for rugged durability and long-lasting performance. The choice of material ensures resistance to wear, impact, and harsh environmental conditions.
Performance & Functionality
The HiViz FASTDOT H3 sight set performs exceptionally well in its intended role, providing clear and reliable aiming points in a variety of lighting conditions. The red fiber optic front sight excels in daylight, offering a bright and easily visible aiming point that significantly speeds up target acquisition.
In low-light or nighttime environments, the green tritium inserts in the rear sight provide a consistent and reliable glow, allowing for accurate sight alignment even when minimal light is available. The balance between the bright front sight and the dimmer rear dots is excellent.
While the front sight can be almost too bright in direct sunlight, this is a minor issue that can be mitigated with a slight adjustment in technique. Overall, the HiViz FASTDOT H3 sights meet and exceed expectations for a combined tritium and fiber optic sight system.
Design & Ergonomics
The all-steel construction of the HiViz FASTDOT H3 sight set gives it a robust and durable feel. The sights add minimal weight to the pistol and do not affect the balance or handling.
The design is relatively simple and straightforward, with no sharp edges or unnecessary features. The factory sight height ensures that the sights do not interfere with holstering or concealed carry. The HiViz FASTDOT H3 provides an intuitive and user-friendly aiming solution.
Durability & Maintenance
The HiViz FASTDOT H3, built from steel, is clearly designed to withstand the rigors of regular use and exposure to harsh conditions. After several months of testing, there are no signs of significant wear or damage. Maintenance is minimal, consisting primarily of cleaning the sights with a soft cloth after each range session.
Given the robust construction and simple design, the HiViz FASTDOT H3 sight set should last for many years with proper care. The tritium inserts are expected to glow for 10-12 years.
Accessories and Customization Options
The HiViz FASTDOT H3 sight set is a self-contained upgrade and does not require any additional accessories for basic functionality. However, aftermarket Glock parts are extremely common, and therefore a variety of upgrades are compatible with the platform as a whole.
Since the sights maintain factory sight height, they should be compatible with most existing holsters designed for Glock MOS models. The sights themselves do not offer any user-adjustable features, such as windage or elevation adjustments.
