Shop 509T footprint red dot sights featuring the enclosed-emitter mounting system used by the Holosun 509T series. The 509T footprint uses its own mounting interface and is different from RMR, DPP, ACRO, and other common pistol optic footprints.
The enclosed-emitter design protects the LED emitter from dirt, debris, rain, and other environmental conditions while providing a durable red dot platform for competition, carry, and duty applications.
Browse our selection of 509T footprint optics for compatible pistol slides and mounting plates. Some optics may include adapters for use with other mounting patterns, but always verify the optic's native footprint and your firearm or mounting plate compatibility before ordering.
