Best Gun Trigger Locks

Trigger locks and gun cable locks are meant to keep your firearm safely stored. Though the purpose is the same, not all gun locks provide the same level of safety. Through our research, we discovered that the best trigger lock is the Master Lock 94DSPT. We found some other options to make your firearm safer too.

Besides being incredibly affordable at around $20, this lock has a lot of things going for it. The trigger lock has a three-digit combination, making it safer and more convenient than a key lock. There’s no worry about losing the key or a child finding the key. 

It adjusts to fit various gun sizes and is made from durable steel and zinc. It also has special rubber pads so it doesn’t scratch your gun’s finish, which is a nice touch. Plus, the lifetime guarantee means that you’ll always have a way to safely lock your gun.

This biometric trigger lock provides quick access by unlocking with a touch of the finger. It also comes with a key and a keypad, just in case the scanner doesn’t work. The biggest complaint is how the lock fits on different firearms—it's not always a snug fit.

This cable lock stands out because it has a combination lock instead of a key, which is rare. We recommend these types of locks over keys, because keys can easily make it into the hands of someone who isn’t the gun owner.

Like our top pick, these trigger locks have a combination style lock and padding on the inside to protect your gun's finish. They are also adjustable to fit the size of the triggers.

At 14 inches, this keyed lock is shorter than our top cable lock by an inch, but that shouldn’t be a problem for most firearms. Its tough construction and trusted brand name make up for the missing inch.

There are several things to consider before buying a gun lock:

• Trigger locks are not for loaded guns. Putting the lock on, taking it off, or even just moving the gun with the lock installed can make the gun go off.
• Gun locks are just one part of gun safety and gun storage. Keep your gun in a gun safe, keep it unloaded, and ideally keep the ammunition in a different location than the gun if you have children or teens in the home.
• Combination or biometric gun locks are generally safer. Combination or finger scan locks are safer because a kid won’t be able to pilfer your key to open the lock. That said, combination locks are easy to reset—perhaps a little too easy. Older children and adults can probably figure out how to reset the code with a quick online search.

The Master Lock 94DSPT is our pick for the best gun trigger lock because it is easy to use, adjustable, and comes from a trusted brand. Its combination gun lock style means no lost keys, and its padding protects your gun's finish.

For our gun trigger lock review, we researched expert advice on firearm safety devices, read customer reviews, and consulted with gun owners. We combined that with decades of safety and security expertise to come up with the best recommendations.
