What Makes Safes Different?

Aside from the price tag, factors that differentiate these secure units include steel thickness, fire resistance and storage space, and they should all be considered wisely given the value and importance of your assets. To help you make an educated purchase decision, here are some of the key points you might want to take into consideration.

Storage Space

In reality, gun safes are used to store more than just weapons. They’re extra secure, heavy-duty units, so it makes sense that you might want to keep other valuables or important documents in there, too.

Bear in mind that a product boasting a capacity of 80 guns probably disregards the possibility of fitting other items inside. If you want to make a smart purchase, first decide what valuables you wish to secure as well as your gun. Buying a larger capacity unit than you currently need might be a good idea if you want to be primed to accommodate a growing collection.

Fire Rating

Unfortunately, burglary isn’t the only thing you need to protect. A house fire can reach temperatures up to 1300 degrees Fahrenheit, and that could cause significant damage to guns, ammunition and valuables.

If you live in a remote area where it’ll likely take a long time for help to arrive, you might want to purchase a safe that is fire resistant for at least 60 minutes. It’s recommended to aim for 30 minutes of fire protection as a minimum in all situations.


You’ll likely be looking to buy a safe mainly to keep prying hands away, and the thickness of the steel walls and door will affect how vulnerable it is to attack. Safes often come with a steel gauge rating, and the lower the gauge, the thicker the steel.

You might be tempted to make a financial saving by opting for a product with a high gauge steel rating, but it’s important to remember some burglars will go to extreme lengths to penetrate secure units.

Go for a minimum of 1-inch thick steel if you have a collection of 30 or more valuable firearms, which means a 12-gauge steel rating. Additionally, choosing a safe with a thick steel construction is likely going to be friendlier towards your insurance premiums if you intend to cover its contents.

Locking Mechanism

Both dial and electronic locking mechanisms are an excellent way to secure your safe, the main difference being how long it takes to open them. The electronic option is going to cost you a little more, but it means quicker access when time is of the essence.

The dial lock has proven effective for over a century and a half, with up to a million possible combinations for burglars to attempt to crack. But in the event an intruder enters your premises in the middle of the night, an electronic lock gives you much quicker access to your firearms.

The main drawback with the electronic alternative is its dependence on battery power and vulnerabilities to EMP devices, though they are designed to remain locked shut in the event of a power failure. However, that’s not going to be much use when you have a home to defend. The best locks are those which combine the two mechanisms, but they’re going to be the most expensive option in most cases and usually only available on high-end products.


When it comes down to it, you’ll want to know what the manufacturer is prepared to cover should something go wrong with your purchase. It can prove extremely expensive to have a locksmith provide access to the safe’s contents if the locking mechanism fails – their whole purpose is to keep people out! The most expensive manufacturers might cover every component of the safe for a lifetime, but for mid-range and down, it’s a good idea to read the small print and find out exactly what the manufacturer is willing to guarantee.

Security Ratings

Manufacturers assign secure ratings to some – but not all – gun safes to help give an idea of a safe’s capabilities. However, it’s still recommend considering the above factors individually, as ratings can be subjective and mainly used by the insurance companies to provide quotes.

On the lower end of the scale, RSC rated products have proven effective against a five-minute attack test, and that’ll get you covered for somewhere around $5000 worth of contents. The highest rating (U.L. TRTL-30x6) stands up to a 30-minute blow torch and tool attack, which is enough to get you covered for up to a million dollars’ worth of contents.

Top Five Stack On Gun Safe Reviews

To help you purchase a product that’s going to prove effective for a reasonable price, here are some of the most popular Stack-On safes taking the above factors into account. Different storage units are designed to accommodate different needs, so you’ll need to consider what matters the most to you if you want to make a wise investment.

Stack-On SS-16-MB-C 16-Gun Security Safe

  • Holds up to 16 firearms
  • Matte black exterior
  • Drill-resistant, 3-digit combination lock
  • ​Fully carpeted interior
  • ​Dimensions:
    20.81"W x 20.06"D x 55.63"H
  • Six locking points
  • Limited three-year warranty

With a capacity of up to 16 guns at 54 inches in length, this unit might be a good option for those with small firearm collections. It also features a removable shelf and 2-tray organizer, but using these will result in less space for weapons.

The door has a 3-digit combination lock, which means there are limited number of code possibilities for potential thieves to crack. However, the hardened steel plate behind the lock provides resistance to drill attacks for added security.

As a mid-range gun safe aimed at the lower end of the market, its steel construction gives it a low gauge, and its lack of actual fire resistance is a major drawback. However, at its price with a three-year limited warranty, it could prove to be quite a bargain for those on a budget.


  • High value
  • Good thickness for a mid-range safe
  • Drill resistance


  • Little resistance to fire
  • Limited number of possible combinations
  • Inadequate space for large collections

Stack-On SS-22-MB-C 22 Gun Fully Convertible Security Safe

  • Holds up to 22 firearms
  • Black epoxy paint finish with chrome accents
  • Drill resistant, three digit combination lock
  • Fully carpeted interior
  • Dimensions:
    20.71"W x 17.27"D x 59"H
  • Six locking points
  • Limited three-year warranty

This secure storage unit accommodates up to 22 rifles, and with four adjustable shelves, there’s room for a nice amount of valuables if you’re willing to sacrifice some weapon space. It weighs less than some similar-sized alternatives and could be more vulnerable to prolonged attacks.

It features a drill-resistant plate behind its three-digit combination locking mechanism, but a lack of fire resistance might make it the wrong choice if you intend to store valuable electronics or flammable goods securely.

With its light weight and low price tag, this safe might be the ideal choice for those only in need of gun safety and the ability to transport it.


  • High value
  • Convertible storage space
  • Drill resistant
  • Easy to move


  • Low fire resistance
  • Its light weight could make it vulnerable to theft

Stack-On BC-18-MB-E-S 18 Gun Buck Commander Safe

  • Holds up to 18 rifles
  • Fire resistant up to 30 minutes
  • Electronic locking mechanism
  • Drill-resistant steel plates located behind the lock
  • Reinforced steel doors with fire retardant material
  • Dimensions:
    19"W x 20.25"D x 55"H
  • Five locking points
  • Limited three-year warranty

With fire resistance up to 30 minutes in temperatures up to 1400 degrees, this might be the safe for you – especially if you live in a remote area out of proximity of the emergency services. However, though it provides excellent resistance to the elements, the sacrifice is lower capacity.

With a maximum capacity of 18 rifles, the Stack-On 18 Buck Commander Safe might not be suitable for those with large or growing gun collections, but it has the advantage of being easily converted to store other valuable items.

This safe the first safe in this review which features an electronic mechanism, which is ideal for those who prioritise quick access and a large number of possible combinations.


  • Excellent fire resistance
  • Convertible storage space
  • Quick access


  • Lower than average number of locking points
  • Low gun capacity

Stack-On Elite 24 Gun Security Safe

  • Holds up to 24 rifles
  • Fire resistant up to 30 minutes
  • Black epoxy paint finish
  • Dimensions:
    26.75"W x 43"D x 59"H
  • Reinforced steel doors with fire retardant material
  • Ten locking bolts
  • Limited three-year warranty

This safe is another Stack-On safe that provides fire resistance for up to 30 minutes, and it might be suitable for those looking to keep larger collections out of harm’s way with its 24 rifle capacity.

The safe’s convertible storage space and a door storage system, which includes removable zippered bags, means it could be a good candidate if you’re looking for a product which has flexible security options for a broad range of valuables.

With ten locking bolts and an electronic drill-resistant lock, it puts up a good defence against tool attacks.


  • Easy access
  • Large capacity
  • Convertible storage space


  • Higher price than similar alternatives

Stack-On E-36-MG-C-S Elite 36-Gun Security Safe

  • Holds up to 36 rifles
  • Fire resistant up to 30 minutes
  • Three digit combination lock with drill resistant plate
  • Matte green paint finish
  • Dimensions:
    26.75"W x 32.5"D x 59"H
  • Ten locking bolts
  • Limited three-year warranty

If you’ve got a gun collection too large for any of the products reviewed so far, the Elite 36-Gun Security Safe might be more suitable for you. As the name suggests, this item can hold up to 36 rifles, or its storage space can be converted to secure 18 guns plus storage for other valuables. It also features door storage with removable holsters for pistols.

With ten locking bolts and a drill-resistant steel plate behind the lock, it’s a difficult safe to penetrate, though the three digit combination lock is lagging behind regarding security compared to other locking mechanisms with a limited number of possible combinations.


  • Large capacity
  • Excellent fire resistance
  • Convertible storage space


  • Electronic locks are preferred
  • A little on the pricey side

Our Recommendation

Stack-On E-24-MB-E-S Elite 24 Gun Security Safe – Given that one of the biggest complaints about recent gun safe purchases is a lack of space, the recommended safe is the Elite 24 with its ability to store an impressive-sized collection and convertible space. While the Elite 36 has a higher capacity, you’ll be required to pay an extra 200 dollars, and this isn’t great value when it hasn’t got the necessary additional security features to bolster its appeal.
