Night Fision Co Witness Tritium Sights G17/19/45 W/RMR Orange Review

The Night Fision Co Witness Tritium Sights G17/19/45 W/RMR Orange Made a Bold First Impression

As a seasoned outdoor and tactical gear specialist, I’ve seen countless sight systems come and go, each promising unparalleled accuracy and low-light performance. However, the Night Fision Co Witness Tritium Sights G17/19/45 W/RMR Orange immediately caught my eye with its claim of 30% more tritium than competitors and its lower 1/3rd co-witness compatibility with popular red dot optics. The promise of enhanced visibility and seamless integration with my existing Glock setup was too compelling to ignore.

I was consistently frustrated with the dim, hard-to-see factory sights on my Glock 19, especially when paired with my RMR. I needed sights that could provide a bright, clear aiming point in both daylight and low-light conditions and co-witness effectively with my red dot, offering a reliable backup in case of optic failure. The Night Fision sights seemed to offer a robust solution.

Upon unboxing, I was immediately impressed by the solid construction and clean lines of the Night Fision sights. The nitride-coated steel sight bodies felt incredibly durable, and the bright orange front ring was instantly attention-grabbing. These sights felt noticeably more substantial than the factory Glock sights they were replacing.

Compared to Trijicon HD XR sights and Ameriglo GL-429s, the Night Fision sights offered a unique combination of features. While the Trijicons are known for their durability and the Ameriglos for their value, the Night Fision sights stood out with their emphasis on maximum tritium brightness and optimized co-witness height. I chose these over the others hoping for superior low-light visibility and a perfect integration with my RMR.

My first impression was one of excitement and anticipation. The Night Fision Co Witness Tritium Sights G17/19/45 W/RMR Orange appeared to be a well-designed and thoughtfully engineered product that could potentially solve my visibility issues and enhance my shooting experience. I couldn’t wait to get them installed and put them to the test.

First Use Experience

I first tested the Night Fision sights at an outdoor range during a bright, sunny day, followed by an evening session under low-light conditions. The orange front sight ring was remarkably easy to acquire in daylight, providing a clear and distinct focal point even against cluttered backgrounds. Under low-light conditions, the tritium vials glowed brightly, offering excellent visibility without being distracting.

The Night Fision sights performed admirably in both wet and dry conditions. Even with sweaty hands, the textured sight bodies provided a secure grip for racking the slide. After a few magazines, I quickly adapted to the sight picture and found that my shot groups tightened considerably compared to my previous Glock sights. There were no issues at all with first use.

After several months of consistent use, the Night Fision Co Witness Tritium Sights G17/19/45 W/RMR Orange have proven to be incredibly durable and reliable. There are no signs of wear and tear on the nitride-coated steel sight bodies, even after repeated exposure to cleaning solvents and holster friction. The tritium vials continue to glow brightly, providing consistent low-light visibility.

Maintaining the Night Fision sights is simple; a quick wipe down with a clean cloth after each range session is all that’s required. Compared to my previous experiences with other aftermarket sights, the Night Fision sights have significantly outperformed in terms of brightness, durability, and overall usability. They have become an indispensable part of my Glock setup.
