Sig Sauer ROMEO-X SIG-LOC Pro reflex sight Circle Dot Red
Fully enclosed reflex sight for slides with the SIG-LOC PRO footprint, secured from beneath the slide.
This configuration
This version has the red Circle Dot reticle. A button press switches between dot (2 MOA), circle (32 MOA) and circle with dot.
Features in practical use
Bottom mount (SIG-LOC)
The sight is secured from beneath the slide; the SIG-LOC system creates five points of contact between slide and optic.
Longer focal length
According to the manufacturer the bottom mount allows a longer focal length that reduces parallax and reticle distortion.
Enclosed and purged
The optical system is fully enclosed, sealed and purged; a rear glass window closes the housing. The housing has a drain port.
Gas deflector with LCI
The housing includes a gas deflector for the pistol Loaded Chamber Indicator (LCI).
MOTAC and MAGNETAC
MOTAC switches the sight off without motion; MAGNETAC automatically turns it off in a compatible holster and back on when drawn.
15 brightness settings
There are 12 daylight and 3 night vision settings (D.A.R.C.); the buttons are recessed and, according to the manufacturer, can be operated with gloves on.
Side-loading battery
The CR2032 battery is changed from the side without removing the sight; runtime is up to 20,000 hours (continuous, medium setting, dot only).
Waterproof to IPX-8
The manufacturer rates this model IPX-8.
