The AmeriGlo L Black/Black night sights for Glock 43X/48 deliver a clean, reliable upgrade for shooters who want solid night sight capability without complications. These 1L height sights are engineered specifically for optics-ready MOS slides, giving you a precise co-witness picture if you ever run a slide-mounted red dot like the Holosun 507K, 407K, Vortex Defender, or Shield EPS Carry. Whether you're building a duty rig, a competition gun, or a carry setup that might accept an optic in the future, the L height sits right in the middle of the sizing spectrum—not too tall, not too short, and familiar to shooters transitioning between guns.
The front sight features a serrated blade and a .220-inch height that cuts through low-light work. The rear sight's square notch and .295-inch overall height establish a natural sight alignment that most shooters pick up instantly. Both are finished in flat black, which means zero glare and a classic, professional appearance. The black-on-black setup keeps you honest—you're relying on your sight picture and trigger control rather than a glowing dot, which is exactly what you want in a true backup sight or when an optic isn't mounted.
AmeriGlo's reputation for fit and finish holds up here, and these sights are cut to tight tolerances for Glock MOS platforms. The serrated front blade bites your sight picture, while the square rear notch stays true and repeatable run after run. If you run multiple sight height preferences or plan to swap optics and backups across your firearms, AmeriGlo's full size lineup (1L, 2L, 5L, XL, 2XL, 3XL, 5XL) means you can dial in exactly the sight picture geometry that works for your grip and eye.
| Front Sight Height | 0.220 in. (5.59 mm) |
| Front Sight Style | Serrated, Black |
| Front Blade Width | 0.115 in. (2.92 mm) |
| Rear Sight Height | 0.295 in. (7.49 mm) overall |
| Rear Sight Finish | Flat Black |
| Rear Notch Shape | Square |
| Rear Blade Height | 0.215 in. (5.46 mm) |
| Rear Notch Width | 0.150 in. (3.81 mm) |
| Size Designation | 1L |
| Fits | Glock 43X/48 MOS (and other Glock MOS platforms) |
Yes. The 1L height is optimized for an elevated co-witness picture with Holosun 507K, 407K, Vortex Defender, and Shield EPS Carry optics on Glock MOS slides. You'll be able to see through the optic window while maintaining a usable sight picture below it.
AmeriGlo offers multiple height sizes (1L, 2L, 5L, XL, 2XL, 3XL, 5XL) to accommodate different optics, slide platforms, and shooter preferences. The 1L is the mid-range option—taller than standard iron sights but lower than the tallest variants. If you're unsure which height works for your specific optic, measure your optic window height and choose accordingly.
These sights work either way. They function as reliable iron sights for shooting without an optic, or as a dependable backup when a slide-mounted red dot is your primary aiming system. The serrated front and square notch are durable and repeatable for both roles.
Yes, these sights are designed for Glock MOS (Modular Optics System) slides on the 43X and 48, which have the milled interface for mounting optics and sight cuts. If your slide is not an MOS variant, these sights will not fit.
