SIG SAUER ROMEO-X SIG-LOC Compact Enclosed Circle-Dot Sight

SIG SAUER ROMEO-X SIG-LOC Compact Enclosed Circle-Dot Sight

The SIG SAUER ROMEO-X SIG-LOC Compact is a fully enclosed pistol reflex sight engineered specifically for compatible SIG-LOC optic-ready P365 slides. This black SORX1600 configuration combines a 2 MOA red center dot with a 32 MOA circle, providing a precise aiming point inside a larger visual reference that is easy to locate during presentation. With 1x magnification and a 24mm objective, it delivers an unmagnified sight picture in a compact housing sized for the P365 platform.

Five-Point SIG-LOC Connection

SIG-LOC means Leverage Optimized Connection. The system mounts the optic from beneath the pistol slide and establishes five points of contact between the sight and a compatible SIG-LOC cut. This geometry is designed to create a strong mechanical lockup and reduce the chance of the optic shifting under recoil or impact. The low mounting deck also supports absolute co-witness with standard-height iron sights on compatible installations.

The bottom-mount layout allows a longer optical focal path without creating an unnecessarily tall housing. SIG SAUER uses that space to minimize parallax and reticle distortion, producing a crisp aiming reference across a forgiving viewing window. Because SIG-LOC is a specialized interface, buyers should confirm that the intended P365 slide is cut for the SIG-LOC Compact footprint before ordering.

Enclosed Housing for Everyday Protection

The emitter and optical system are fully enclosed, sealed, and purged. This protects the projected reticle from rain, lint, dust, mud, and other debris that can obstruct an exposed emitter. The housing is made from rugged 7075 aluminum, giving the sight structural strength while retaining the compact proportions expected from a P365-oriented optic.

A distortion-free aspherical glass lens provides a clear viewing surface. LensArmor abrasion-resistant protection helps defend the exterior lens surfaces, while SpectraCoat anti-reflection coatings improve light transmission and reduce distracting reflections. The enclosed design is rated IPX-7 for water resistance, supporting reliable operation in wet conditions when installed and maintained according to SIG SAUER’s instructions.

Circle-Dot Reticle and Illumination Controls

The SORX1600 uses a red circle-dot reticle consisting of a fine 2 MOA center dot surrounded by a 32 MOA circle. The center dot supports deliberate aiming, while the larger circle offers a bold reference for quick alignment. Fifteen illumination settings include 12 daylight levels and three dedicated night-vision settings, allowing the reticle to be matched to changing ambient light and compatible night-vision equipment.

MOTAC motion-activated illumination turns the reticle on when movement is detected and powers it down during inactivity. This feature helps conserve battery life while keeping the optic ready when handled. A side-loading CR1632 battery provides a rated runtime of up to 20,000 hours. The side-access compartment allows battery replacement without removing the optic from the slide or disturbing its mounting position.
