Trijicon
If you run a suppressor on your Glock slim frame, standard iron sights won't cut it—the can sits too high and blocks your sight picture. The Trijicon Suppressor Height Sights for Glock Slim Frame (Model GL243C601142) fix that problem. Engineered with an additional rise to clear the added height of a suppressed barrel, these tritium night sights let you maintain a proper sight alignment whether you're shooting suppressed at the range, in low light, or in a defensive scenario. Built for Glock 42, 43, 43X, and 48 models, they bring the same rugged reliability Trijicon is known for to the smallest frames in the Glock lineup.
The three-dot sight picture uses tritium-phosphor-filled lamps that glow in darkness and remain visible in bright daylight, thanks to a sapphire jewel that distributes light evenly across the sight face. Orange front and black rear lamps give you fast target acquisition whether conditions are bright or dim. Protective aluminum sleeves with silicone rubber cushioning keep the sights intact through hard use and rough handling.
Because these sights are taller than standard height, they also work as backup iron sights if you're running a Trijicon RMR or other red dot on your slide. That dual-purpose design makes them a smart choice for shooters who want options. The green tritium lamps are backed by a 12-year warranty from the date of manufacture—confidence that these sights will be there when you need them.

Yes—that's exactly what they're designed for. Standard height sights sit too low to be usable when a suppressor is mounted, since the suppressor body rises above the slide. These suppressor-height sights are taller so they align properly over the can, giving you a functional sight picture even when suppressed.
Yes. In addition to clearing a suppressor, the height makes them suitable for use as backup iron sights alongside a Trijicon RMR or other optics mounted on your slide. This gives you a secondary aiming solution if your primary optic fails.
These sights are engineered for Glock slim frames: the 42, 43, 43X, and 48. Do not use on full-size or compact Glock models, as they are fit specifically to the slim frame slide.
The tritium-phosphor-filled lamps glow in darkness without needing batteries. In bright daylight, the sapphire jewel collects ambient light and distributes it evenly across the sight face so the dots remain visible. This allows you to aim quickly and accurately in low-light and high-light conditions alike.
