If you're running a Glock 48 or 43X and looking to mount a Holosun 407K, 507K, EPS, or EPS Carry, this steel red dot mounting plate is exactly what you need. Right out of the gate, it feels like a high-quality, precision-machined upgrade that inspires confidence both in build and performance.
Fit & Finish: The plate is machined from durable steel and fits the Glock MOS slide like a glove. Installation is straightforward—no need for gunsmithing—and the mounting hardware included is solid. The tolerances are tight, ensuring your optic holds zero under recoil and rough use.
Co-witness Iron Sights: The built-in iron sights are a major plus. They offer a lower 1/3 co-witness with most Holosun optics, so you’re covered if the dot ever fails. The sight picture is clean, and the backup irons are well-aligned, giving peace of mind for duty, concealed carry, or competition use.
Compatibility: Perfectly matched for the Holosun K footprint optics. Whether you're going with the slim and rugged 407K/507K or the fully enclosed EPS Carry, this plate holds everything tight and true.
Performance: After a few hundred rounds downrange, the plate stayed rock solid. No loosening, no shift in zero, and the sight picture remained crisp. It’s a huge improvement over plastic or aluminum plates and clearly designed with real-world use in mind.
Final Thoughts: This plate is a must-have if you’re upgrading your Glock 48/43X MOS for a micro red dot. The addition of steel backup sights is a smart move, making it a complete and reliable solution. For the price, the quality and peace of mind are hard to beat.
