RMSc Footprint Red Dot Sights

The Shield RMSc footprint is the standard for micro pistol red dot sights — the compact mounting pattern found on slim, single-stack and micro-compact carry pistols like the SIG P365, Glock 43X/48 MOS, S&W Shield Plus and Springfield Hellcat. If your carry gun is cut for the RMSc, these optics fit directly. At Xtreme Tactical we stock RMSc-footprint red dots from Holosun, dispatched fast from the UK.

This collection covers the Holosun 507K/407K series and the fully sealed EPS Carry family. Running a full-size or duty pistol? See our RMR footprint red dot sights. Browse all pistol dot sights, sealed enclosed red dot sights, or shop the full Holosun range.

Frequently Asked Questions

What is the RMSc footprint?
The Shield RMSc is a smaller mounting pattern designed for slim and micro-compact pistol slides — narrower than the RMR, so the optic sits flush on a thin slide.

Which pistols use the RMSc footprint?
Popular RMSc-cut carry pistols include the SIG P365 series, Glock 43X/48 MOS, S&W Shield Plus / Equalizer, Springfield Hellcat and many other micro-compacts. Confirm your slide cut before ordering.

Is the EPS Carry an RMSc optic?
Yes — the Holosun EPS Carry uses the RMSc footprint while adding a fully enclosed emitter for extra reliability. The larger full-size EPS does not share this footprint.
