Holosun RML Red Laser 1mW/5mW Handgun Sight - Black Universal Rail Mount

The Holosun RML red laser handgun sight brings affordable, effective target acquisition to duty guns, competition pistols, and defensive carry setups. This universal rail-mount laser mounts to any Picatinny-equipped pistol—whether you're running it on a compact carry gun or a full-size duty frame—and gives you a red aiming point that works in daylight, low light, and indoors. Holosun built the RML with real-world gun handling in mind: it's housed in durable polymer, sits low on the rail to play nice with weapon-mounted lights and standard holsters, and holds zero reliably through thousands of dry fires and live rounds.

Switching between 1mW and 5mW output lets you dial in brightness for your environment without draining the battery needlessly. Adjustments are tactile and audible—you'll feel and hear each click as you dial in windage and elevation—so you don't need to remove the sight to dial it in or verify your setting. The IPX8 waterproof rating means it'll handle rain, sweat, and occasional submersion without skipping a beat.

Setup is straightforward: mount it to your rail, drop in the included 1/3N lithium battery, and dial it to your zero. The RML is ideal for shooters who want the speed and accuracy of a laser without the bulk or heat signature of a full red dot, or as a secondary aiming tool alongside your existing optic. Whether you're training at the range, competing in pistol sports, or carrying for personal defense, a quality handgun laser rewards practice and builds confidence in target engagement.

Frequently Asked Questions

Will the Holosun RML fit my pistol?

The RML mounts to any handgun with a Picatinny rail system, including most modern carry guns, tactical pistols, and competition shooters. If your gun has a Picatinny accessory rail, the RML will mount directly.

Can I use this laser with a weapon light?

Yes. The RML was specifically designed for weapon light compatibility and won't interfere with mounted flashlights or standard holster fit, so you can run both laser and light on the same rail.

What battery does it use and how long does it last?

The RML uses a 1/3N lithium battery, which is included. The lower 1mW mode will extend battery life for extended use without sacrificing visibility in most lighting conditions.

How do I zero the laser to my gun?

The RML features tactile and audible windage and elevation adjustments. You can hear and feel each click as you dial it in at your shooting distance, eliminating the need to remove the sight during zeroing.
