The NIGHT FISION CO WITNESS TRIT SIGHTS G43/43X W/507K BLACK Made a Bold First Impression
For years, I’ve carried a Glock 43X as my EDC. The factory sights were… adequate. They served their purpose, but lacked the visibility I needed in low-light scenarios and the precision for accurate co-witness with a red dot. Enter the NIGHT FISION CO WITNESS TRIT SIGHTS G43/43X W/507K BLACK, promising enhanced tritium brightness and a perfect co-witness with my Holosun 507k.
I needed a sight system that provided both excellent day and night visibility and the ability to accurately co-witness with a red dot optic. The factory sights were just not cutting it in low light and weren’t tall enough to adequately co-witness with the red dot. I was looking for a set that would give me confidence no matter the lighting conditions.
Upon opening the package, the first thing I noticed was the robust construction. The black nitride finish looked incredibly durable. Compared to other aftermarket sights I’ve used, the NIGHT FISION set seemed to be built to a higher standard.
I considered Trijicon HD XR sights and Ameriglo GL-429 sets, but the NIGHT FISION‘s promise of 30% more tritium and a lower 1/3rd co-witness sealed the deal. Other options felt like compromises; NIGHT FISION seemed to directly address my specific needs. The price point being slightly lower than the Trijicons was a nice bonus too.
My initial impression was one of excitement tempered with a healthy dose of skepticism. Would these sights really live up to the hype? I was eager to get them installed and put them to the test.
Real-World Testing: Putting NIGHT FISION CO WITNESS TRIT SIGHTS G43/43X W/507K BLACK to the Test
First Use Experience
The first test was at my local indoor range. I was specifically looking to see how well the sights performed in a controlled low-light environment. The NIGHT FISION sights immediately impressed.
The tritium vials glowed brightly in the dim light. The high-visibility front ring was easy to acquire against a dark target. It was a dramatic improvement over the factory sights.
Extended Use & Reliability
After several months of carrying my Glock 43X with the NIGHT FISION CO WITNESS TRIT SIGHTS G43/43X W/507K BLACK, I can attest to their durability. I’ve put several hundred rounds downrange. There has been no noticeable degradation in brightness or finish.
The nitride coating has held up exceptionally well to daily wear and tear. Cleaning is a breeze. A quick wipe-down after each range trip is all that’s needed to keep them in top condition. The sights have performed exceptionally well and I feel confident in their reliability.
Breaking Down the Features of NIGHT FISION CO WITNESS TRIT SIGHTS G43/43X W/507K BLACK
Specifications
The NIGHT FISION CO WITNESS TRIT SIGHTS G43/43X W/507K BLACK are specifically designed for Glock models 42, 43, 43X, and 48. They provide a lower 1/3rd co-witness with Holosun 507k and similar height optics.
These sights boast 30% more tritium than competing brands, ensuring exceptional low-light visibility. The high-visibility front ring enhances target acquisition in daylight. Each set is constructed from nitride-coated steel for maximum durability.
Performance & Functionality
The primary function of these sights, clear sight picture in all light conditions, is executed flawlessly. The combination of the bright tritium vials and the high-visibility front ring provides a distinct advantage. It’s faster target acquisition and improved accuracy, especially in scenarios with less than ideal lighting.
The accuracy is on par with other quality aftermarket sights I’ve used. The lower 1/3rd co-witness with my Holosun 507k is perfect, providing a clear backup sighting system. The only minor improvement I could suggest is perhaps a slightly sharper edge on the rear sight for one-handed slide manipulation.
Design & Ergonomics
The NIGHT FISION sights have a sleek and functional design. The all-black finish gives them a tactical look that complements the Glock 43X perfectly. The weight is negligible, adding no noticeable bulk to the pistol.
The sight picture is clean and uncluttered. The high-visibility front ring immediately draws your eye to the target. I found the learning curve to be minimal. Anyone familiar with standard pistol sights should adapt to these quickly.
Durability & Maintenance
The nitride-coated steel construction gives me confidence that these sights will last for years to come. After months of use and abuse, there are no signs of rust or corrosion. Maintenance is straightforward.
A simple cleaning with a brush and some solvent is all that’s needed to keep them in good working order. The 16 Year Brightness Guarantee from NIGHT FISION further reinforces my confidence in their longevity.
Accessories and Customization Options
The NIGHT FISION CO WITNESS TRIT SIGHTS G43/43X W/507K BLACK are primarily a standalone upgrade. However, their compatibility with the Holosun 507k (and similar height optics) makes them an integral part of a customized pistol setup. No extra accessories are included, since they are not required for this design.
They are not designed to be used with suppressor height sights. They are optimized for red dot co-witnessing and standard carry configurations. If you are planning on adding a compensator, you may need to adjust your recoil spring.
