Shield Sights RMSd Features The Shield Sights RMSd Glass Edition mounts to Shield s own RMSc footprint and uses the company s patented mechanism to enable co-witnessing with standard iron sights which considerably reduces the training time needed to transition to a red dot equipped pistol. Its D-shaped crystal-clear glass lens carries no filters to disturb the image of the world seen through the sight giving a clean true-color sight picture in every lighting condition. Automatic brightness adjustment keeps the 8 MOA dot visible across changing light without requiring the shooter to manage settings manually. Machined from aerospace-grade aluminum to precise tolerances the housing stands up to the recoil of daily carry use while keeping the optic lightweight. A side-accessible battery drawer means the sight never has to be removed from the slide to change its CR1632 battery which helps preserve a dialed-in zero over the life of the optic. At roughly 9 000 hours of average battery life and a weight of just 0.65 ounces the RMSd Glass Edition is built to run for a long time without adding noticeable bulk to a carry pistol. The low-profile design co-witnesses with many Glock factory sights removing the need for separate suppressor-height sights on compatible pistols. The Shield Sights RMSd Glass Edition is for sale at GrabAGun for concealed carry shooters who want a reliable glass-lensed red dot built for everyday use.
