The Overwatch Precision HAVE BLUE MOS Sight set for your Glock handgun is a combat optimized back-up sight set designed to provide a fast, clean sight picture. 

Together with your RMR, the all black .395" high, 0.130" square-bottomed rear notch and .390" tall,  0.105" wide plain black front sight work in concert, giving you blazing fast sight acquisition without sacrificing precision for small targets or longer engagement ranges. The serrated rear of both front and rear sights minimizes glare, and the edges of the rear sight aren't so sharp as to eat the skin off of your body while concealing your handgun and are a perfect back up to your Trijicon RMR. 

With aesthetics inspired by one of our favorite airframes, HAVE BLUE sets the standard for durability, rapid acquisition, and usefulness for one-handed manipulations, all with stunning good looks. The last thing you see before you send a shot is your sights, and let's be real; HAVE BLUE is sexy AF.*
