    1. Stack-On SS-16-MB-E 16 Gun Security Safe

    This matte black Stack-On gun safe is the kind of versatile safe you’re looking for. It keeps your guns stowed away, the only people that can access it are yourself and the people you’ve trusted to grant access to. It’s sturdy, and it won’t fail you in the moments where safety matters. It’s made with heavy gauge steel, and the electronic lock comes with a key bypass, so you’ll be ready to go no matter the state of your keypad. In fact, if someone with the gumption to drill through your lock comes along, the keypad is backed up by a drill-resistant steel plate. The locking mechanisms of this safe are plentiful and sturdy.

    The door comes equipped with active locking bolts located all around the frame of the door, and a set of static bolts on the hinge side to secure the door in the event of the hidden hinges somehow coming loose from the safe.

    The interior of this gun safe is also robust and spacious. The entire interior is carpeted to protect your firearms from scratches and dings once they’re stored, anything could happen once they’re in there, and protecting them from the inside of the safe isn’t necessarily as important as protecting them from the outside, but it doesn’t hurt. The inside of this safe also has Stack-On patented molded barrel rests to keep your long guns in place once they’ve been entrusted to this 16 gun safe. The molded barrel rests have called in a little backup to improve your storage experience in the form of sight standoff inserts so you don’t have to remove your scopes once you’ve found the perfect one for your rifle. You’ll also find a two tray door organizer as well as a single removable top shelf.

    The removable shelf will give you a little extra height if you’re worried about fitting some of your larger rifles into this gun safe, or you can use it once you’ve packed the door organizer full of accessories. This simple addition to the safe adds a world of utility to a safe that’s already far from plain. 

    PROS

    • Spacious and carpeted interior
    • 5 point locking system
    • On-door storage trays
    • Sturdy steel construction

    CONS

    • Not fireproof 

    2Stack-On E-029-SB-E Executive Fire Safe

    The exterior of this safe is just nice to look at. The silver door and the filigree on the border make this an attractive addition to your home. A gun safe doesn’t always have to be a solemn addition to your home.

    They do, however, need to be secure and resistant to break-ins. This Stack-On safe ticks those boxes with confidence. The chrome handle on the door not only looks great, but the chrome adds an extra bit of durability to your purchase. Chrome is resistant to rust, and it’s an extra layer of metal that will keep your handle sturdy and difficult to remove or otherwise tinker with. The handle is responsible for three solid-steel live-action bolts that work in concert with a set of three deadbolts on the opposite end to keep feisty crowbars out of your beautiful new safe and away from your valuables. 

    This safe is fireproof up to about half an hour at temperatures up to 1400-degrees Fahrenheit, you can rest easy even when your safe is hot under the collar. The lock is reinforced with a drill resistant steel plate, and if you want to bolt the safe down, Stack-On includes a set of mounting hardware.

    This is a spacious safe, it comes in just shy of 30 inches, meaning you’ll have plenty of room for your valuables, your ammo, and your firearms, or maybe you just need 30 inches for all of your firearms. Whatever the case, this will give you the room to comfortably arrange the contents to your heart’s content. The interior is fully carpeted, keeping the inside of your safe from damaging your valuables with rigid surfaces and coarse material. It also comes equipped with a pair of adjustable position shelves. Adjustable shelving is just the sort of creature comfort that Stack-On Safes loves to add to their safes to make purchasing one of their offerings worth every cent.

    PROS

    • Pry-resistant doorframe 
    • Fireproof design
    • Carpeted interiors and adjustable shelving
    • Key coded lock can be silenced

    CONS

    • Spacious, but not quite large enough for your longarms

    3Stack-On PFS-1608 Personal Steel Fireproof Safe

    Stack-On PFS-1608 Personal Steel Fireproof Safe with Electronic Lock
    • Electronic lock stores 3-8 digit combination, backup key included. AA Batteries Required, works best with Polaroid AA batteries.

    This little powerhouse is everything you want from a smaller gun safe. The fireproofing here is impressive, protecting your firearms from a blaze up to 1400 degrees-Fahrenheit for about thirty minutes. In the unfortunate event of a house fire sparking right underneath this gun safe, somehow, you can rest easy knowing that your valuables are safe in this safe. 

    The electronic safe is programmable, allowing you to set a custom combination anywhere from 3 to 8 digits in length. The range of combination length is yet another barrier standing between anybody trying to guess your combo and the inside of your safe. This electronic keypad comes with a built-in low battery warning system, so you’ll never be caught with your electronic pants down. Even if the keypad fails you, they include a backup key to bypass the combination lock in the event of failure (or plain forgetfulness). If you’re worried about alerting someone to the operation of your safe, the keypad also has a silent entry option so you won’t be beeping away your location and intent. 

    Inside of the safe, you’ll find a fully carpeted interior, so your firearms won’t topple on top of cold steel shelving, scratching themselves up and exiting their storage worse for wear. The soft interior includes the foam padded removable shelf. This shelf is a nice touch. Gun safes are, of course, great for storing away a few handguns and the ammo you’ve collected, but sometimes your gun safe will also need to serve as a storage space for larger valuables with stranger shapes. Taking out the shelf here will give you the chance to pack anything of any shape, or just giving you more options in terms of strictly gun storage, not every firearm is built exactly the same, after all.

    The door comes equipped with two pairs of solid steel locking bolts, one pair on either side of the door. On the hinged side, you have a pair of deadbolts that keep the door in place in the event of hinge removal, and a pair of live deadbolts that retract when the code is entered on the keypad.

    PROS

    • Fireproof up to half an hour at some pretty intense temperatures
    • Door swings open greater than 180 degrees
    • Mountaing hardware included 

    CONS

    • No option for a combination lock

    422 Gun Steel Security Safe

    Stack-On SS-22-MB-E SS22 Gun Safe, 22, Black
    • Holds 22 rifles or shotguns up to 54 inches tall, or 11 firearms and storage, or all storage

    This gun safe is a comfortable affordable take on gun storage. When you decide on this safe, you’ll be able to choose from an electronic or combination lock. Whichever suits your needs, Stack-On is able to accommodate this large, robust safe. If you opt for an electronic keypad, you’ll be given a pair of manual bypass keys. These keys are a long skeleton type key that is incredibly difficult to replicate, so anybody looking to trick their way into your gun safe is going to have one heck of a time. 

    The 4 adjustable shelves located within the safe are a godsend. This is a sizable safe that benefits exponentially from the ability to rearrange the interior. A capacity for 22 guns is impressive on its face, but the adjustable shelving makes this a safe worth purchasing. The utility you get from the adjustable shelving makes this more than an incredibly secure hanging rack. Any other valuables you happen to need secure storage for will fit snuggly in your customized space. Camera and ammo boxes can be sequestered into their own little corners, and rifles of any size and shape will play nice with the rest of your collection with a short shuffle of the shelving. The patented molded barrel rests that Stack-On stocks this safe to maximize the space you’ll be able to squeeze out of this gun safe. Not many gun safes on the market give you scope standoff inserts to accommodate your sighted pieces. 

    The sturdy steel construction of this safe makes it a no-brainer for your gun storage needs. It’s not just a convenient storage method with adjustable innards. It’s a solid piece storage solution that comes equipped with three 1” locking bolts distributed along the perimeter as well as three opposing 1” deadbolts. Anybody looking to drill through the lock is going to find themselves up against the hardened steel drill-resistant plate, and good luck smashing off the concealed hinges from inside of a locked safe.

    This is a great gun storage solution. The safety measures here are robust and thoughtful, and the interior is considerate to the firearms and valuables you’ll be storing within.

    PROS

    • Fully carpeted interior
    • Adjustable shelving
    • Beautiful epoxy paint finish and chrome accents
    • California-approved Firearm Safety Device

    CONS

    • Not fire resistant

    • Perfect for holding pistols, ammo, supplies and valuables

    Too often when people talk about gun safes, they focus primarily on safes for their longarms. This can leave handgun enthusiasts out in the cold without any handy reviews for smaller cabinets that may be more well-suited to their needs.

    It’s an 18-inch welded steel box with a simple key lock on the front door. The removable shelving is an excellent option for the undecided cabinet owner. You can keep them in and store a decent number of handguns along with your ammo, or if you’ve outgrown your pistol cabinet but you want to utilize it for your larger valuables, you can just yank the shelving out, and suddenly you have an 18-inch steel cabinet for any heirlooms or home savings you can imagine.

    The pre-drilled holes on the bottom of the cabinet are perfect for firm installation on the floor, on top of a larger gun safe, or a sturdy shelf. Stack-On Safes, as their name implies are specifically sized to fit together with their other offerings. This gun security cabinet in particular will fit on top of the 8, 14, and 22 gun cabinets if your collection is large enough for you to want to keep your long and short guns separate and secure. The convenient stacking quality of this gun cabinet makes it a perfect addition to your collection or an excellent starting point. You’ll be able to upgrade in either direction, be it adding pistol accommodations to your storage space, or making room for your rifles once you’ve expanded your horizons after a couple of handgun purchases.
