Buying Guide: What to Look For in the Best Gun Locks
When I’m looking at the best gun locks for added safety, my first thought is always about the type. Not every lock works for every situation, and using the right one is a big part of responsible ownership. The main types you’ll see are cable locks, trigger locks, and chamber locks. Cable locks are super versatile; you thread a steel cable through the action of the firearm, making it impossible to chamber a round or close the action. They’re a great, affordable choice for many types of guns. Trigger locks clamp around the trigger guard to block access to the trigger. A word of caution here: you must ensure the lock doesn’t actually touch the trigger, as pressure could theoretically cause a discharge. For me, chamber locks (or barrel locks) are excellent for added security. They insert directly into the chamber of a pistol or the barrel of a rifle, physically blocking a round from being chambered.
My next non-negotiable is certification. I always look for locks that meet or exceed specific safety standards. In the U.S., the gold standard is certification from the California Department of Justice (CA DOJ) or approval from the nonprofit organization Project ChildSafe. These aren’t just stickers; they mean the lock has been independently tested for strength, durability, and tamper resistance. A certified lock gives me confidence that it’s not just a flimsy piece of hardware.
Durability and construction are huge. I check what the lock body and cable or shackle are made from. A hardened steel cable is much harder to cut than a basic braided wire. The locking mechanism itself should feel robust. I avoid locks with thin, easily-picked keyways or combination dials that feel loose or cheap. For combination locks, I prefer models with discrete, clickable dials over smooth dials, as they can be more precise and harder to decode by feel.
Finally, I think about my specific use case. Is this for long-term storage in a safe (where it acts as a secondary layer), or for quick access in a home-defense scenario? For quicker access, I might lean towards a reliable biometric lockbox that secures the entire firearm, rather than a device that attaches to it. But for general storage and safety, especially to prevent unauthorized access, a traditional cable or trigger lock is a solid choice. Remember, the best gun lock for added safety is the one you will actually use consistently every single time.
Frequently Asked Questions
Are gun locks required by law?
Laws vary significantly by state and locality. Some states have mandatory locking device laws, often requiring a safety device like one of the best gun locks for added safety to be sold with every firearm. Other laws, often called “safe storage” or child access prevention laws, mandate that firearms be stored in a locked container or with a locking device if they could be accessed by a prohibited person, like a child. It’s my responsibility to know and follow the laws in my area.
Can a determined person defeat a gun lock?
Like any security device, gun locks are a deterrent, not an absolute guarantee. A very determined individual with specialized tools and time might defeat some models. However, their primary purpose is to prevent unauthorized, impulsive access—especially by children or visitors. A quality, certified lock significantly increases the effort and time required, which is often enough to prevent a tragedy. They are a critical layer in a complete safety plan.
What’s the difference between a cable lock and a trigger lock?
The main difference is how they secure the firearm. A cable lock threads a steel cable through the gun’s action (e.g., through the magazine well and out the ejection port of a pistol), rendering it inoperable. A trigger lock clamps around the trigger guard to block access to the trigger itself. I find cable locks generally more versatile for different gun types and often consider them more secure, as they physically disable the cycling of the firearm.
Should I use the free lock that came with my gun?
Often, the free lock provided is a basic cable lock that meets certain regulatory requirements. My rule is: using it is infinitely better than using nothing at all. It provides a fundamental level of safety. However, if I’m looking for maximum durability, tamper resistance, or a specific feature like a combination dial, I might invest in a higher-end model from a dedicated security company. The free lock is a great start, but upgrading is never a bad idea.
How do I properly use a chamber or barrel lock?
It’s vital to follow the manufacturer’s instructions exactly. For a pistol chamber lock, you first must confirm the firearm is completely unloaded. Then, you insert the specific locking rod into the chamber. For a rifle or shotgun barrel lock, you insert the device down the barrel from the muzzle end until it seats. The goal is to physically block a round from being chambered. Always, always verify the gun is unloaded before installing any lock, and store the key or combination separately.
