The Fast Box™ Model 40 Hidden Gun Safe is a compact, high-performance safe engineered for gun owners who need secure, rapid-access firearm storage in tight or mobile environments. Originally designed for law enforcement professionals seeking a smaller alternative to the Fast Box 47, the Model 40’s slim profile (40.25" x 13" x 6.5") was crafted to fit seamlessly in truck beds, SUV cargo areas, or other confined spaces. Weighing just 42 pounds, this lightweight yet robust safe is built from 14-gauge welded steel with a textured powder-coat finish, ensuring durability and resistance to tampering. Its versatility has made it a favorite among civilian users for home defense, travel, or discreet storage in nightstands and closets.

The Model 40 features SecureIt’s High-Stress Fast-Access (HSFA) locking system, delivering lightning-fast, reliable entry in high-pressure situations. The customizable 4-digit push-button keypad, backlit for low-light conditions, is paired with a capacitive fingerprint scanner for quick access and a manual key override for redundancy. With no third-party backdoors, your firearms remain fully secure.

Flexible mounting options include pre-drilled holes and hardware, supporting horizontal or vertical storage for one long gun (up to 39.5") or a rifle-handgun combination. The optional CradleGrid™ system allows tailored organization for firearms and accessories. Whether for tactical operations, home defense, or on-the-go security, the Fast Box Model 40 offers unmatched portability, security, and accessibility.

  • Lightning-Fast Access: HSFA locking with backlit keypad and fingerprint scanner ensures quick entry, even in high-stress or low-light scenarios.

  • Compact and Discreet: Fits in small spaces like truck beds, SUVs, nightstands, or closets for hidden, secure storage.

I’ve only used it for a couple weeks now but it works as intended. The finger print reader is not consistent so I use the code instead. This filled an important need at a reasonable price. I would recommend or buy another one.

I Love the Fast box safe , easy to program and install !! 👍 Thank you.

Missing bolts on the inside door panel which needed repair. Name plate screws were also stripped so reorientation was a challenge. Size and weight made it a good fit for my application. Setting codes was not as straight forwarded as I would have liked.

Would have been five starts, but the reset button on the inside of the door was loose on arrival. Was able to tighten it up with some tools, but if I hadn't the wires might have been damaged over time. Otherwise happy with the product.

Love this box. Bought for its light weight and can be moved anywhere and stashed in the smallest of places. Do wish that it was a little bit wider.

Solid construction and fit my needs exactly. I preferred the button system on the old Fastbox 40, they were more tactile and easier to use when not looking. I can’t comment on the biometric lock because I do not use it. Still a good product.

Wonderful item - so glad I got it - works well, easy to use. Feel more safe having set up for self defense.

Works wonderfully, changing the codes for designated entry was great. I was able to place a long gun and a pistol for quick access. Having them secure yet readily available is perfect.

Nice quality metal box. Not thrilled with the biometric (finger print) feature. Tried a digit, then a thumb. Prints save ok and work for a while. Next day is another story. The feature fails until lockout, beeps for 60 seconds, then fails again. Last thing I want half asleep, in the dark, in an emergency.

Numbers and key work fine. Definitely shutting the beep off.

I expected more for the money.

Really high quality and just big enough for my needs. Didn’t even know it had a fingerprint sensor on it and it works amazing.
