Fusion brings biometric access control, an integrated light, and a green laser together in one firearm-mounted system. Designed for compatible handguns, Fusion helps limit access to authorized users while preserving rapid access for an enrolled user. Biometric data is stored locally on the device, and Fusion operates without an app, Wi-Fi, Bluetooth, or cloud storage. Before ordering, check the current Fusion compatibility guide to confirm fit with your handgun and rail configuration. Fusion is currently listed as a slide lock on the California Department of Justice Roster of Approved Firearm Safety Devices. Use the device in accordance with the manufacturer’s instructions and applicable law. Why firearm owners choose Fusion Firearm-mounted protection: Fusion stays attached to a compatible handgun instead of relying on a separate container. Biometric authentication: Enrolled fingerprints provide authorized access without keys or codes. Offline operation: No app, subscription, Wi-Fi, Bluetooth, or cloud connection is required. Integrated visibility tools: A built-in LED light with up to 550 lumens maximum output and a Class 3R green laser are incorporated into the device. Purpose-built construction: Precision-machined 6061-T6 anodized aluminum chassis with a DLC-coated steel arm. Rechargeable power: USB-C charging with up to nine months of standby time under specified conditions. Fusion is designed to unlock in under 0.25 seconds when properly installed, configured, maintained, and used by an enrolled user. Actual performance can vary with conditions and use. Watch the installation video to see setup and operation in more detail. Compatibility matters Fusion is not universally compatible. Fit depends on the specific handgun, rail, and configuration, and aftermarket modifications can affect fit or function. Review the current compatibility guide before purchasing.
