C&H Precision Back Up Iron Sights Glock 43/48 MOS for Trijicon RMRcc & RMR

The C & H Precision Back Up Iron Sights for Glock 43X/48 MOS is a high-accuracy, unmagnified 1x auxiliary sighting package engineered to deliver a clean secondary sight picture on slimline concealed-carry pistols. CNC-machined from high-grade steel and treated with a rust-resistant matte black finish, this physical sight set is specifically optimized to pair with Glock 43X MOS and Glock 48 MOS slides utilizing an aftermarket adapter plate to mount a Trijicon RMRcc or standard RMR optic. It features an elevated "LowWitness" profile height configuration—utilizing a .420" tall front blade and a .430" tall rear sight—which intentionally sits into the lower field of view to clear the combined deck height of the slide cut, the adapter plate, and the optic base. This tactical geometry functions as a lower 1/6 to 1/8 co-witness alignment, giving operators an entirely unobstructed view through their primary red dot lens while maintaining a highly usable physical backup alignment if internal electronics or batteries fail. Sourced through premium tactical components storefronts like EuroOptic, this non-electronic accessory kit slides directly into standard factory slots without requiring permanent slide modifications.
