Product Description
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″ x 11″ x 6″) was crafted to fit seamlessly in truck beds, SUV cargo areas, or other confined spaces. Weighing just 45 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, while a padded interior protects your gear. Whether for tactical operations, home defense, or on-the-go security, the Fast Box Model 40 offers unmatched portability, security, and accessibility.

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.
2nd item not shipped. Received one had loose reset button, requiring repair, and lock mechanism very persnickety. Now awaiting Customer Service shipment of 2nd ordered item as warranty coverage. Overall very poor experience for the Model 40.
