Sig Sauer Romeo-X Compact SIG-LOC 3 MOA Enclosed Red Dot

The Romeo-X Compact SIG-LOC is an enclosed red dot built around Sig's SIG-LOC mount, the system that came out of the Romeo-M17 program. Instead of riding on screws alone, SIG-LOC sets the optic down into the slide with five points of contact, so recoil and hard knocks do not walk the zero.

Because the optic mounts from the bottom, the lens sits farther from the emitter, which cuts parallax and dot distortion when your head is not perfectly centered. The 3 MOA red dot sits in a closed housing that keeps out rain and debris. There are 15 brightness settings including night vision, and it runs on a CR1632. It is designed for SIG-LOC optic ready P365 slides. Weight is 1.24 oz.
