WILL FUSION FIT YOUR HANDGUN?
Fusion is compatible with many popular handguns, but fit depends on the specific model, rail, and configuration. Confirm compatibility before ordering.

PROTECTION SHOULD NOT FORCE A FALSE CHOICE.
If you own a firearm, you want to protect the people you love in every sense of the word. That means helping keep it out of a child’s or other unauthorized person’s hands. It also means knowing you can access it if you truly need it.
Our mission is simple: to help firearm owners do both, without making them choose which kind of protection matters most.
That’s why we developed security that stays with the firearm, recognizes the authorized user, and isn’t confined to one room or fixed storage location.
WHY FUSION
DESIGNED AROUND THE REAL-WORLD TRADEOFF.
Authorized-owner readiness
An enrolled fingerprint releases Fusion directly, without searching for a separate key or entering a code.
One integrated system
Biometric access control, a white light, and a green laser are built into one firearm-mounted device.
Biometric data stays on the device. No app, Wi-Fi, Bluetooth, cloud account, or subscription is required.
