The Trijicon RMR footprint is the most widely adopted mounting standard for pistol red dot sights — used across countless optics-ready slides and adapter plates. If your handgun's slide cut or optic plate is RMR-pattern, these sights drop straight on. At Xtreme Tactical we stock RMR-footprint red dots from Holosun and Trijicon, dispatched fast from the UK.
This collection covers full-size optics including the Holosun 507C/407C series, the competition 507COMP, and the Trijicon SRO. Carrying a slimline pistol instead?

Frequently Asked Questions
What is the RMR footprint?
It's the mounting pattern of the Trijicon RMR — two screws and a recoil-lug profile that has become an industry standard. Many pistols are cut for it directly, and most adapter-plate systems offer an RMR plate.
Will an RMR-footprint optic fit my pistol?
If your slide is milled for the RMR or your optics-ready pistol includes an RMR plate, yes. Always confirm your slide cut or plate options before ordering — footprint compatibility is exact.
RMR or RMSc — which do I need?
RMR suits full-size and duty pistols; the smaller RMSc footprint suits slim, single-stack and micro-compact carry guns. Check your slide cut to be sure.
