Optics Footprint Guide

If the optic footprint is wrong, your whole setup is wrong. This is the fast practical guide I use before mounting any pistol optic so I do not waste time, plates, or zero confirmations.

The Big Footprints You Need To Know

RMR Pattern

Most common duty/defensive pattern. Tons of optics and aftermarket plate support.

RMSc / K Pattern

Popular on slimmer concealed-carry pistols. Great for micro compact setups.

ACRO Pattern

Enclosed-emitter friendly footprint increasingly common on modern optics-ready slides.

DPP Pattern

Still relevant depending on plate ecosystem and specific optic choice.

My Mounting Workflow

  • Confirm exact slide cut and optic footprint before you buy.
  • Use the correct plate and screw length; verify thread engagement.
  • Torque to manufacturer spec and apply the right thread locker.
  • Reconfirm torque after initial range session.
