Stop Box USA
Stop Box Pro
Your defensive pistol, one press away for you and locked to everyone else. The StopBox PRO is a mechanical handgun retention box with no batteries, no keypad, and no key to hunt for at 2 AM.
- Mechanical Lock
- No Batteries
- Under 1 Second
- Fits Full-Size + Optic
- 81 Combinations
- Made in USA
The StopBox PRO is StopBox's full-size handgun retention device, built around their patented all-mechanical finger-code lock. Press the lid, run your combination, press the thumb lock, and it is open. A practiced code takes under a second and works the same in the dark, because it is muscle memory rather than a glowing keypad.
StopBox is a family-owned company that builds these in its own facility in Spokane, Washington, from glass-reinforced polycarbonate-ABS with steel reinforcement. Their own test drops one from 35 feet with a weighted gun inside.
What it holds
The interior runs 9.25 by 7.15 by 1.75 inches, sized for a full-size pistol wearing a red dot and a weapon light, with room alongside for a spare magazine or a flashlight. If your nightstand gun has an optic on it, this is the version to buy: the smaller StopBox Compact exists, but the PRO is the one that swallows a dressed-up modern pistol without a fight.
Why mechanical matters
Nothing about this lock can go dead. No battery to check, no biometric sensor to misread a sweaty thumb, no electronics to fail on the one night that matters. The finger-code mechanism is entirely mechanical, with 81 possible combinations you set yourself using the included hardware. It is the same logic as a quality mechanical watch: fewer failure points, longer service life, and it works the day you need it because it works every day.
The code is also what makes it child-resistant. Random pressing does not open it, a deliberate sequence does, and there is nothing lit up inviting small hands to try. StopBox says it plainly on their own page and we will repeat it: this is a handgun retention device, not a handgun safe. It prevents tampering and unauthorized quick access while keeping your pistol at the ready. For long-term storage of unattended firearms, a rated safe is still the right tool.
Where it goes
- Bedside. The reason most people buy one. Defensive access for you, locked to everyone else in the house.
- Vehicle. A locked container on the seat or in the console instead of a pistol loose in the glovebox, and it accepts a security cable so the box itself is anchored to the car.
- Travel. Low profile, under two pounds, and padlock compatible. TSA rules require checked firearms in a locked hard-sided container, and StopBox builds the PRO to that use. Confirm current TSA and airline policy before you fly.

Why we stock it
Dark Horse Guns & Ammo has this conversation at the counter weekly: how do I keep a defensive gun both ready and out of the wrong hands? Most answers fail one side of that question. Electronic safes are only as reliable as their batteries, and a loose pistol in a drawer fails the other direction entirely. The StopBox PRO is the best answer we have found at this price, and the 11,000-plus reviews on StopBox's own site say a lot of owners agree.
Frequently asked questions
Is the StopBox PRO a gun safe?
No, and StopBox says so themselves. The PRO is a handgun retention device: a locked, child-resistant, tamper-resistant box that keeps a defensive pistol ready for you and closed to everyone else. It is not a rated safe, and for long-term storage of unattended firearms Dark Horse Guns & Ammo recommends a proper safe.
Does the StopBox PRO use batteries or biometrics?
No. The lock is entirely mechanical. There is no battery, no fingerprint reader, no keypad, and no app. A practiced finger code opens it in under a second, and nothing about it can go dead or fail to read.
Will a full-size pistol with a red dot fit in the StopBox PRO?
Yes. The PRO interior measures 9.25 by 7.15 by 1.75 inches and is sized for full-size handguns wearing a red dot and a weapon light. The smaller StopBox Compact fits subcompact and compact pistols without large accessories.
How many combinations does the StopBox PRO have?
The mechanical finger-code lock supports 81 possible combinations, and you set your own with the hardware included in the box.
Can I keep the StopBox PRO in my car?
Yes, vehicle use is one of the most common reasons people buy one. The PRO is security cable compatible, so the box can be anchored inside the vehicle rather than simply sitting on a seat. Vehicle firearm storage laws vary by state, and buyers are responsible for knowing the rules where they drive.
Can I fly with the StopBox PRO?
TSA requires firearms in checked baggage to be unloaded, locked in a hard-sided container, and declared at the airline counter. The PRO is a lockable hard-sided container that is also padlock compatible, and StopBox markets it for exactly this use. Confirm current TSA and airline policy before you travel.
Is the StopBox PRO child-resistant?
Yes. Opening it requires a deliberate press sequence that random pressing will not produce, and there is no lit keypad to attract attention. No container replaces supervision and safe firearm habits.
Where is the StopBox PRO made?
StopBox builds the PRO in its own facility in Spokane, Washington. It is an American-made product from a family-owned American company.
Does buying a StopBox PRO require an FFL transfer?
No. The PRO is a storage device, not a firearm, so there is no FFL paperwork. Buy it from Dark Horse Guns & Ammo at the counter in Yerington, Nevada, or have us ship it to you directly.
Where can I try one before buying?
Dark Horse Guns & Ammo is at 518 W Goldfield Ave, Yerington, Nevada 89447, open Tuesday through Saturday, 10:00 AM to 5:00 PM. Call (775) 344-8022 or send us a message. Come run the lock yourself, because thirty seconds of pressing the code teaches you more than any video.
The StopBox PRO is a handgun retention device and is not a substitute for a rated safe, adult supervision, or safe firearm handling.

Nothing here is legal advice.
