First Thoughts on the HiViz FASTDOT H3 For Glock MOS 9/40 Tritium/Fiber Optic Night Sights
For years, I’ve relied on Glock pistols for both duty carry and personal defense, and a constant quest has been to optimize their performance, especially in low-light situations. The HiViz FASTDOT H3 For Glock MOS 9/40 Tritium/Fiber Optic Night Sights promise a blend of daylight visibility with nighttime illumination, piquing my interest as an experienced tactical gear specialist. HiViz aims to give shooters a clear sight picture around the clock.
I’ve struggled with finding the “perfect” sight for my MOS Glock. Standard tritium sights can be dim during daylight hours, and fiber optic sights are useless in complete darkness. This combination approach seemed like a great solution.
Upon unboxing, the first thing that struck me was the robust all-steel construction. The sights felt solid and well-machined, giving a sense of durability. The contrast between the bright red fiber optic front and the subtle green tritium rears was immediately apparent.
I was deciding between these sights and the Trijicon Bright & Tough Night Sights, as well as the Ameriglo Pro-IDOT sights. I chose the HiViz FASTDOT H3 For Glock MOS 9/40 Tritium/Fiber Optic Night Sights for their combination of fiber optic and tritium, thinking it offered the best of both worlds. It seemed a more versatile solution for various lighting conditions.
My initial excitement was high, tempered with a bit of skepticism about whether they could truly deliver on their promise of 24/7 visibility. Time to see if these sights could live up to the hype!
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 test involved a trip to the local shooting range, followed by a night-time home defense drill scenario in a controlled environment. I mounted the HiViz FASTDOT H3 For Glock MOS 9/40 Tritium/Fiber Optic Night Sights on my Glock 19 MOS. The initial range session focused on target acquisition speed and accuracy in broad daylight.
The bright red fiber optic front sight was incredibly easy to acquire, even against brightly lit targets. Transitioning to an indoor range with dimmer lighting, the fiber optic still provided a noticeable advantage compared to standard blacked-out sights. However, it was not as bright as full daylight.
Moving to the night-time drill, the tritium rear sights provided a consistent, albeit subdued, glow. The front sight wasn’t illuminated by tritium which made the contrasting fiber optic a bit distracting. After a few repetitions, my eyes adjusted.
Extended Use & Reliability
After several weeks of consistent use, including weekly range sessions and participation in a low-light shooting course, the HiViz FASTDOT H3 For Glock MOS 9/40 Tritium/Fiber Optic Night Sights have proven to be reasonably durable. The steel construction has held up well, with no noticeable wear or damage from recoil or handling. The fiber optic rod remains securely in place.
Maintenance has been straightforward, primarily involving occasional cleaning with a soft brush and solvent to remove carbon buildup. These sights do require a little more attention than simple iron sights. I’ve made sure to be mindful of the fiber optic rod when using solvents.
Compared to my previous experiences with tritium-only sights, the HiViz FASTDOT H3 For Glock MOS 9/40 Tritium/Fiber Optic Night Sights offer superior daytime visibility. They offer acceptable nighttime capabilities, however, they are not my preferred choice. I prefer the clear and definitive dot of dedicated tritium sights in true dark conditions.
