The Hiviz FASTDOT H3 Red front/Green Rear For SIG P320 P365 9mm Made a Bold First Impression
The Hiviz FASTDOT H3 Red front/Green Rear For SIG P320 P365 9mm sight system promises a blend of fiber optic brightness and tritium reliability, offering 24/7 illumination for SIG Sauer’s popular compact and duty pistols. I’ve always been a proponent of having reliable sighting systems on my firearms and I was looking for something that would be a direct replacement of my existing stock sights on my P365 without needing extensive gunsmithing. This combination of technologies aims to provide a clear and fast sight picture in any lighting condition, a claim I was eager to test.
My journey to the Hiviz FASTDOT H3 began with a persistent frustration: inadequate sight visibility in low-light scenarios with my standard SIG P365. While the factory sights were acceptable in daylight, they became almost useless at dusk or indoors. I needed a solution that offered constant visibility without relying on batteries or external power sources.
The unboxing experience was straightforward; the sights were securely packaged. My initial impression was positive: the steel construction felt robust, and the contrast between the red front and green rear was immediately noticeable. The low profile design also pleased me, hinting that it wouldn’t snag or interfere with concealed carry.
I considered other options, including TruGlo Tritium Pro sights and Meprolight Tru-Dot sights. I ultimately chose the Hiviz FASTDOT H3 because of its hybrid approach, combining the best of both fiber optic and tritium technologies. I wanted the brightest possible sight picture during the day and reliable illumination at night, without sacrificing a low-profile design.
My first impression was one of cautious optimism; I was excited to see if the Hiviz FASTDOT H3 would live up to its claims. The real test would be on the range and in practical shooting scenarios.
Real-World Testing: Putting Hiviz FASTDOT H3 Red front/Green Rear For SIG P320 P365 9mm to the Test
First Use Experience
I installed the Hiviz FASTDOT H3 sights on my SIG P365 and headed to my local range for the first test. I wanted to see how these sights would perform under varied lighting conditions. My testing occurred in an indoor range with controlled lighting, as well as an outdoor range with bright sunlight and overcast conditions.
The Hiviz FASTDOT H3 performed admirably in all lighting environments. The fiber optic front sight was incredibly bright and easy to acquire in direct sunlight. During low-light indoor situations, the tritium vials provided a clear and visible aiming point.
The installation process was straightforward, although drifting out the old sights and installing the new ones required a sight pusher tool. After getting them professionally installed, I found the sights intuitive to use, requiring very little adjustment. After a few magazines, I was consistently hitting center mass at various distances.
The only initial surprise was how much brighter the fiber optic front sight was compared to the rear in bright sunlight. It almost felt like a red dot sight, which, while initially startling, proved beneficial for quick target acquisition.
Extended Use & Reliability
After several months of consistent use, the Hiviz FASTDOT H3 sights have held up exceptionally well. I’ve put several hundred rounds downrange with them and the sights remain securely in place. There’s been no noticeable degradation in brightness or visibility.
The steel construction has proven durable, with no signs of wear and tear beyond minor cosmetic blemishes from holster use. I routinely clean my firearms after each range visit, and the Hiviz FASTDOT H3 sights are easy to wipe down and maintain. I periodically inspect the tritium vials to ensure they maintain their glow, though Hiviz warranties them for 12 years.
Compared to other aftermarket sights I’ve used, the Hiviz FASTDOT H3 surpasses them in versatility and consistent performance. Other fiber optic sights are only effective in bright environments. Other tritium sights can sometimes be dim. The Hiviz FASTDOT H3 offers the best of both worlds.
