Crimson Trace RAD Micro 3 MOA Red Dot Reticle, Matte Black, Compact/Sub-Compact Pistol Sight with Radiant Ambient Light Sensor

The Crimson Trace RAD Micro is a compact red dot sight built specifically for carry pistols. If you shoot a modern compact or subcompact—and especially if your slide is already cut for optics—this ultra-slim reflex sight gives you the speed and target-acquisition advantage of a red dot without the bulk or weight penalty. The 3 MOA red dot is sharp and fast to pick up, and the large window makes finding your sight picture natural even from retention or unconventional firing positions.

What sets the RAD Micro apart is the Crimson Trace RADIANT Ambient Light Sensor, which automatically adjusts dot brightness based on your lighting conditions. No manual brightness fiddling on a range, in a dim indoor bay, or during that low-light hunt. The rear sight notch lets you co-witness with your front iron sight, so you've got a backup aiming reference if the battery dies or the optic fails—a smart redundancy for a carry gun. The sight mounts directly to the CT RAD Micro footprint, and it's also compatible with Shield RMS and JPoint footprints, so you've got cross-platform flexibility if you move it between slides.

Crimson Trace engineered the RAD Micro from 7075 Series aerospace aluminum, 30% stronger than the 6061 aluminum you'll find in comparable sights. The top strap design is a thoughtful touch—it deflects impact force downward if you drop the sight, reducing stress on the lens. Rated IPX4 for water resistance, the RAD Micro holds up to heavy use and weather. A CR2016 battery lasts over 20,000 hours (more than two years of typical use), and the bottom-mounted battery compartment keeps changes simple and the profile low.

Windage and elevation are user-adjustable, so you can dial your zero without gunsmithing. The entire package comes backed by Crimson Trace's CRIMSON Protect Lifetime Warranty.

Frequently Asked Questions

What pistols is the RAD Micro designed for?

The RAD Micro is built for compact and subcompact pistols with slides cut for the CT RAD Micro footprint. It's also compatible with Shield RMS and JPoint mounting cuts, so if your slide supports any of those patterns, the RAD Micro will fit.

Can I use the RAD Micro with iron sights as a backup?

Yes. The RAD Micro has a notch cut into the rear that lines up with your front iron sight, allowing you to co-witness. This gives you an aiming reference if the optic fails or the battery dies.

How does the ambient light sensor work?

The CT RADIANT Ambient Light Sensor automatically adjusts the brightness of the red dot to match your surroundings—brighter in daylight, dimmer indoors or in shade. You don't have to manually fiddle with brightness settings.

How long does the battery last?

The CR2016 battery lasts over 20,000 hours, which equals more than two years under typical use. Battery access is bottom-mounted, so changes are quick and field-expedient if needed.
