The Night Fision Glock Slimline 43X MOS Optic Plate and Backup Sight Combo for the Holosun EPS Carry footprint (Night Fision part no. GLK-OPBS-EPSC-43X-YGZX) bundles a 17-4 stainless steel plate with co-witness iron sights. Night Fision designed it for Glock Slimline 43, 43X and 48 pistols with the version 1 MOS factory cut, the RMSc pattern. This version has a yellow ring tritium front sight and a blank rear. It lets you run a Holosun EPS Carry or another optic with the same footprint on a slim carry gun and still keep irons as a backup.

A slim carry gun leaves little room for mistakes, and a plate and sights that are designed to work together take most of the guesswork out of adding a red dot. The lower 1/3 co-witness keeps the irons usable without crowding the optic window. Order it from our Lubbock, Texas gun shop for fast, insured shipping, and see more red dot mounts while you are here.
