When it comes to protecting your firearms, not all gun safes are made equal. Many people compare Cannon Gun Safes and Stack-On Gun Safes because they are both popular, widely available brands. But when you look closer, you’ll notice that Cannon often pulls ahead, especially for buyers who value strength, reliability, and peace of mind. Let’s explore why Cannon Gun Safe is often considered the better choice.

A gun safe’s main job is to keep guns secure from thieves, children, and even fire. Here, the details matter.
Cannon Gun Safes use thick, strong steel. For example, many Cannon models use 12-gauge or even 10-gauge steel for the safe walls. Stack-On Gun Safes often use thinner, 16- or 18-gauge steel. Thicker steel is harder to cut, pry, or drill through. This means Cannon safes can resist break-in attempts longer.
Cannon also welds their seams fully, which means fewer weak spots. Stack-On sometimes uses spot welding, which can be easier to break open with tools.
Construction Comparison
| Feature | Cannon Gun Safe | Stack-On Gun Safe |
|---|---|---|
| Steel Thickness | 10-12 gauge | 16-18 gauge |
| Welding | Full seam | Spot welds |
| Door Bolts | Thicker, more bolts | Fewer, thinner bolts |
Security Features
The lock is the heart of any gun safe. Cannon usually equips its safes with UL-listed, high-security electronic or mechanical locks. These locks go through tough testing. Stack-On often uses basic electronic locks, which are sometimes less reliable and easier to bypass.

Hinge placement makes a difference, too. Most Cannon safes have internal hinges, making it much harder to attack the door with tools. Stack-On models often use external hinges, which can be a weak point.
Locking System Comparison
| Aspect | Cannon | Stack-On |
|---|---|---|
| Lock Rating | UL-listed, high security | Standard electronic/mechanical |
| Re-locker | Yes | No |
| Hinge Type | Internal | External (often) |

Fire Protection
Fire can be just as dangerous as theft. Cannon Gun Safes are known for strong fire ratings. Many models offer protection for 60 minutes at 1200°F or better. Stack-On’s fire-rated safes often provide only 30 minutes at 1400°F or less, and many entry-level models have no fire protection at all.
Cannon uses multiple layers of fireboard in the walls and door. They also install expandable door seals that swell during a fire, blocking smoke and heat. Stack-On sometimes skips the door seal or uses cheaper materials.
Fire Protection Comparison
| Fire Rating | Cannon | Stack-On |
|---|---|---|
| Duration | Up to 60 minutes | Up to 30 minutes |
| Temperature | 1200°F | 1400°F |
| Door Seals | Expandable | Basic or none |
Warranty And Customer Service
Cannon’s lifetime warranty is one of the strongest in the industry. If your safe is damaged by a fire or break-in, Cannon will repair or replace it. Stack-On usually offers a one-year limited warranty, and does not cover fire or theft damage.

Interior Features And Usability
When you open a Cannon Gun Safe, you’ll notice adjustable shelving, soft interior lining, and extra pockets for small items. These features help you organize handguns, documents, and valuables.
Stack-On safes often have basic shelving and less padding. Some models lack door organizers or extra storage. If you want to store more than just a few rifles, these small touches matter.
Cannon also often includes interior electrical outlets and lights. This makes it easier to charge devices or see inside your safe at night.
Price Vs. Value
At first glance, Stack-On Gun Safes often cost less. For example, a basic 18-gun Stack-On safe can be found for under $400, while a comparable Cannon model may cost $600 or more. But it’s important to look at value, not just price.
Cannon safes last longer and provide better protection. If your firearms or valuables are worth thousands of dollars, spending a few hundred more on a better safe is smart insurance.
A common mistake is buying a cheap safe, only to upgrade later after a scare or break-in. Many owners wish they had invested in Cannon from the start.

Real-world Example
One user shared that after a house fire, his Cannon safe protected family documents and guns, despite intense heat. The safe’s door seal activated, and the items inside survived. He received a replacement safe through Cannon’s warranty. In contrast, Stack-On owners often find their safes warped or breached in similar situations.
Who Should Choose Cannon?
- People with valuable firearms or documents
- Those who live in high-crime or fire-prone areas
- Anyone who wants true peace of mind
Stack-On may be fine for low-value items or where fire/theft risk is low. But if you want a safe that can truly protect, Cannon is the better investment.

Frequently Asked Questions
Is Cannon Really More Secure Than Stack-on?
Yes. Cannon Gun Safes use thicker steel, stronger locks, and better design. They resist break-in attempts longer, making them more secure.
Do All Cannon Safes Have Fire Protection?
Most do, but always check the model details. Many Cannon safes offer at least 60 minutes of fire protection, which is better than most Stack-On models.
Why Are Stack-on Safes Cheaper?
Stack-On uses thinner steel, simpler locks, and fewer safety features. This lowers cost but also reduces security and fire resistance.
Can I Bolt Down A Cannon Safe?
Yes. Cannon safes have pre-drilled holes for bolting. This adds another layer of security by making it very hard for thieves to move the safe.
What If My Cannon Safe Is Damaged In A Fire?
Cannon offers a lifetime warranty covering fire or theft damage. They will repair or replace your safe, which is rare among gun safe brands.
