Grit & Gear: Testing the Ameriglo Sig Sauer Black Sights SG-402, SG-504, SG-400F, SG-450R.
The Ameriglo Sig Sauer Black Sights SG-402, SG-504, SG-400F, SG-450R. are designed as a no-nonsense, all-black sight upgrade for Sig Sauer pistols. Offered by Ameriglo, these sights promise improved target acquisition through a clean sight picture, eliminating distractions from colored inserts. My experience as a seasoned outdoor and tactical gear specialist has always emphasized the importance of reliable and functional equipment, and sights are no exception.
I was looking for a set of sights that would provide a clean, uncluttered sight picture for both daytime range use and low-light scenarios where I might need to rely on ambient light. The factory Sig sights on my P226 were functional, but the three-dot system sometimes felt distracting, pulling my focus from the front sight during rapid target acquisition. The promise of simplified, all-black sights intrigued me.
Upon unboxing, the Ameriglo sights felt solid and well-machined. The matte black finish was even and appeared durable, suggesting they could withstand the rigors of regular use. Their weight was negligible, and the overall design was straightforward and purposeful, aligning with my preference for minimalistic, functional gear.
I considered other all-black sight options from Trijicon and Dawson Precision, but the Ameriglo set won out due to its price point and the promise of a drop-in fit, requiring no gunsmithing. I wanted a simple, effective upgrade without the hassle of extensive modifications or a hefty price tag. I was cautiously optimistic; the simplicity was appealing, but I needed to see how they performed in real-world conditions.
Real-World Testing: Putting Ameriglo Sig Sauer Black Sights SG-402, SG-504, SG-400F, SG-450R. to the Test
First Use Experience
My initial testing took place at an outdoor shooting range under bright, sunny conditions. I mounted the Ameriglo Sig Sauer Black Sights SG-402, SG-504, SG-400F, SG-450R. on my Sig Sauer P226 9mm. The black-on-black sight picture took a little getting used to after years of using three-dot systems.
Once I adjusted, however, the focus on the front sight became much more pronounced, leading to tighter groupings at 15 yards. The sights performed admirably in bright conditions, offering a clear and distraction-free view of the target. There were no immediate issues, although I was curious to see how they would fare in low-light situations.
Extended Use & Reliability
After several months of consistent use, the Ameriglo sights have proven to be remarkably durable. There are no noticeable signs of wear and tear, despite frequent range trips and occasional exposure to adverse weather conditions. The matte black finish has held up well, resisting scratches and fading.
Maintenance is incredibly simple; a quick wipe down with a lightly oiled cloth is all that’s required to keep them clean. Compared to my previous experiences with painted sights that chipped easily, these Ameriglo sights have significantly exceeded my expectations. They provide a consistent and reliable sight picture.

Accessories and Customization Options
