Let’s Talk About L2D Combat Co-Witness/Suppressor Height Fiber Optic Sight Set, Glock 9mm/.40S&W/.357 SIG
As someone entrenched in the tactical and outdoor gear world for over a decade, I’ve seen countless sight systems come and go. But the L2D Combat Co-Witness/Suppressor Height Fiber Optic Sight Set, Glock 9mm/.40S&W/.357 SIG immediately caught my eye with its promise of enhanced visibility and co-witness capability. These sights claim to offer a superior sight picture and increased accuracy for Glock users, something I was eager to test myself.
I was seeking a reliable set of iron sights that would co-witness with my red dot optic on my Glock 19, while also being tall enough to clear a suppressor. OEM Glock sights simply wouldn’t cut it, and many aftermarket options lack the robust construction I demand for a duty-grade pistol. The initial impression was positive, noting the solid steel construction and vibrant fiber optic inserts.
Compared to sets from Trijicon and Ameriglo that I’ve used, the L2D Combat set seemed to offer a more substantial protective housing around the fiber optic rod in the front sight, a critical factor for durability. While Trijicon provides tritium illumination, I preferred the brighter fiber optic option for daytime shooting. I picked this set, betting on L2D’s reputation for quality and the sight’s specific design catering to both co-witnessing and suppressor use.
My first impression was one of cautious optimism. The build quality was immediately apparent, but the true test would be how they performed under real-world conditions.
Real-World Testing: Putting L2D Combat Co-Witness/Suppressor Height Fiber Optic Sight Set, Glock 9mm/.40S&W/.357 SIG to the Test
First Use Experience
I initially tested the L2D Combat sights at my local shooting range, focusing on target acquisition speed and accuracy at distances of 7, 15, and 25 yards. I was primarily interested in how well they co-witnessed with my Holosun 507C red dot. The weather was clear and sunny, ideal conditions for fiber optic sights to shine.
The L2D Combat sights proved incredibly easy to acquire, the bright fiber optic front sight drawing my eye quickly to the target. They perfectly co-witnessed with my red dot, sitting in the lower third of the optic’s window, exactly as I’d hoped. There were no initial issues; the installation was straightforward, and the sight picture was clean and crisp.
Extended Use & Reliability
After several months of consistent use, including weekly range sessions and a carbine/pistol training course in varying weather conditions, the L2D Combat sights have held up remarkably well. There are no signs of significant wear and tear, and the fiber optic rods remain securely in place and vibrantly bright. The black nitride finish has proven resistant to scratches and corrosion.
Cleaning is a breeze; a quick wipe-down with a lightly oiled cloth is all that’s needed to keep them in top condition. Compared to other fiber optic sights I’ve used in the past, the L2D Combat set definitely outperforms them in terms of durability and overall ruggedness. They have instilled confidence in their reliability as a backup sighting system.

The rounded edges of the sights prevent snagging on clothing or gear, which is important for concealed carry and tactical applications.
The sights are relatively easy to install, although a sight pusher tool is recommended for proper installation without damaging the finish. There is a slight learning curve for those unfamiliar with suppressor height sights, but the benefits in terms of co-witnessing and suppressor clearance quickly outweigh any initial adjustment period.

Given the steel construction and black nitride finish, the L2D Combat sights are built to last. The protective housing around the fiber optic rod is a significant advantage, preventing breakage and ensuring long-term reliability. Regular cleaning is simple; a quick wipe with a clean cloth is generally sufficient.
The sights are designed for longevity and resistance to the elements. It is unlikely that frequent repairs will be needed under normal usage.
Accessories and Customization Options
The sight set includes the necessary screws for installation, and the rear sight also features a set screw for added placement security. While there aren’t many “accessories” for iron sights, the key customization aspect is the ability to choose different colored fiber optic rods to suit individual preferences.
