Overview
Built for Glock pistols equipped with slide-mounted red dot optics, this sight set is intended to provide a precise co-witness iron sight picture while also serving as a back-up option. It is sized for Glock 42, 43, 43X, and 48 models, including MOS slides, and uses a tall 1L configuration to support optic use. The front sight features tritium illumination with a green lamp and white outline, while the rear is flat black for a clean, uncluttered sight picture.

Considerations & Trade-offs
- Designed for optic-equipped pistols, this set is intended as a co-witness or backup iron sight solution rather than a standalone sighting system.
- Fit is listed for Glock 42, 43, 43X, and 48 with MOS compatibility noted, so it is not presented as a universal fit for every Glock configuration.
- The rear sight is flat black, which keeps the setup simple but does not add rear illumination.
- GLOCK is specifically noted as not manufacturing, authorizing, endorsing, or warranting this product, so compatibility and fit should be confirmed for the intended pistol setup.
