Forward Controls Design Glock G43X/G48 Backup Iron Sight With No Tritium

The Forward Controls Design Glock G43X/G48 backup iron sight with no tritium is a purpose-built co-witness solution for shooters running a red dot on a compact Glock. Developed in collaboration with Ameriglo, these sights sit at lower-third co-witness height with the Trijicon RMRcc—meaning your backup irons stay below your optic's line of sight, clearing your view while remaining instantly accessible if your dot fails. The no-tritium front sight comes serrated, with a steeper 25-degree back strap angle that sheds clothing and gear as you draw. The rear sight is horizontally serrated for a solid grip and fast target acquisition.

These aren't your standard mass-produced gun-counter sights. Forward Controls Design and Ameriglo engineered features specifically for duty use and serious carry: softened front-sight corners to reduce snagging, tight tolerances that hold zero through rough handling, and domestic manufacturing. The company built these with law enforcement in mind—many agencies mandate metallic backup sights on duty-carried red dot pistols, and the G43X/G48 combo with RMRcc meets that requirement without compromise.

Installation requires a sight pusher or qualified gunsmith; dovetail tolerances vary, and these sights are spec'd tight rather than loose, so professional fitting is worth the investment. This is the non-tritium, serrated front version—if you prefer night-sight luminescence or a non-serrated profile, check the full BIS G43X/G48 lineup.

Frequently Asked Questions

Will these sights co-witness with my RMRcc on a G43X or G48?

Yes. The front and rear sight heights are set for lower-third co-witness when paired with the Trijicon RMRcc red dot, keeping your backup irons below the optic's view and ready as a secondary aiming system.

Do I need a gunsmith to install these?

Professional installation by a qualified gunsmith is strongly recommended. These sights are spec'd with tight tolerances to hold zero reliably; dovetail fit varies by pistol, and proper fitting or minor material removal may be necessary. A competent gunsmith will handle this quickly and correctly.

What's the difference between this version and other BIS G43X/G48 options?

This is the no-tritium, serrated front sight version. Forward Controls Design also offers tritium and white-outline options on the front sight. All versions share the same height, co-witness spec, and duty-grade features.

Are these sights agency-approved for duty carry?

The G43X and G48 with RMRcc and metallic backup sights meet the duty requirements of many agencies that mandate co-witnessing irons on red dot pistols. Verify your department or agency's specific sight specifications before purchasing.
