Your protection and satisfaction are our top priorities.
How It Works:

B.O.S. Lock integrates with your firearm's natural function to control the slide. When locked, the retention arm secures the slide in the rear position, keeping the chamber visibly empty and preventing the firing pin from reaching the ammunition, making the gun inoperable. Authorized users unlock the system with a fingerprint scan, allowing the slide to move forward, loading a round, and making the firearm operational.

(1) Mark III B.O.S. Lock device

It Changed My Mind

Was a skeptic but thought the concept was cool so figured I'd give it a try. The material quality, products execution, and the biometric reads through lotions. How this is only $250 is a mystery.

Gun Safety for homes with children

I have always stored our gun in a safe since we have small children and this product has completely alleviated my stress about the gun getting in the wrong hands. Now I can leave it out and know myself and my husband are the only two people who can access it. We ordered during pre order and it took almost a month before we got it but it was worth the wait. Going to get my sister one for Christmas.

I LOVE MY BOSLOCK

I am beyond happy with this safety. It's innovative, insanely fast, and easy to use. Also, to all that say biometrics are iffy, this one is worlds better than any other biometric I have used. Boslock is really a top not product IMO.
