Safe storage is important to ensure that the gun is not only secure from theft or use by a home invader but also to keep it away from curious kids, impulsive teens, and other unauthorized users who could potentially pose a danger to themselves and others.

Advantages of Trigger Locks

The popularity of the trigger lock makes sense.  

Trigger locks are inexpensive or even free in some areas through Project ChildSafe, an initiative to promote gun safety.

Trigger locks don’t require the gun to be locked up in a case, cabinet, or safe and can be quickly put on and taken off of the gun.

They’re also very portable, adding very little weight or bulk to the gun, and are very easy to use.

So why, then, does anyone even bother using anything else?

Disadvantages of Trigger Locks

Well, trigger locks aren’t all good.

For one, trigger locks should never be used on a loaded gun. The bar that connects the two sides of the lock comes far too close to the trigger, and the trigger can easily be hit while the lock is being put on or removed.

Dropping or jostling the gun or even just applying too much pressure while the gun lock is on the gun can result in an accidental discharge.

Negligent Discharge — almost as bad as an accidental discharge.

Trigger locks are also less secure than other forms of gun storage, like a safe or locked case.

Their locks can be easily picked, drilled through, or even pried open with a screwdriver. The same key can also be used on many different locks, even if they’re supposed to be keyed differently.

For these reasons, trigger locks should not be used as a security method for go-to home defense guns. Use a quick-access gun safe instead.

Trigger locks are better used as a backup security method for hunting guns or guns reserved for the range.

Best Gun Trigger Locks

Now that we’ve discussed what you should and shouldn’t count on trigger locks for, let’s talk about a few of our favorite trigger locks currently on the market.

1. Master Lock 94DSPT Combination Trigger Lock

Master Lock is somewhat of a go-to brand for trigger locks, and the Master Lock 94DSPT Trigger Lock is one of their most popular.

The 94DSPT Trigger Lock has a durable steel and zinc body and uses a three-digit combination that you can easily set – and reset – yourself.  

Combination locks mean you don’t have to worry about keeping up with a key and can give access to several people without having to get extra keys or store a key in a common location. 

Since you can reset this lock, you can always choose a new combination if you no longer want someone to be able to access the weapon.

The width of the lock can be adjusted using an included ratchet, which allows this trigger lock to fit securely on just about any handgun, rifle, or shotgun.

A positive locking mechanism keeps the lock secure, and the back of the lock is padded to prevent it from scratching the finish of your guns.

Master Lock also offers a lifetime warranty on all of their firearms products, including the 94DSPT Trigger Lock and our next lock, the Master Lock 90TRISPT Trigger Lock.

Its affordability, ease of use, and durability make it easy for us to call it our Editor’s Pick.

2. Master Lock 90TRISPT Key d Trigger Locks, Keyed Alike

The same steel and zinc body, adjustable width, and padded back as the 94DSPT Trigger Lock, but with a different locking mechanism.

Instead of a combination, the Master Lock 90TRISPT is a keyed lock with a 4-pin tumbler cylinder to prevent picking.

Available in packs of two or three, the Master Lock 90TRISPT Keyed Trigger Locks are keyed alike, which means that each of the locks included in the set can be unlocked with the same key.  

This adds a lot of conveniences if you want to secure multiple guns, but it also means you can’t give people access to certain firearms and not others unless you use a different locking system.

Like the Master Lock 94DSPT Trigger Lock, this lock can be used on any rifle, shotgun, or handgun.

While these may look identical to the 90TRISPT above, these locks have a unique feature.

So what’s the difference?

As the title implies, each Master Lock 90DSPT is keyed differently. This means each lock you buy will use its unique key.  

While this may be less convenient for you than having a single key for all your locks, it allows you to restrict access to specific guns by providing someone with only the key for the locks on the guns you want them to be able to use.

4. Identilock Trigger Lock

We’ve covered several of the many biometric gun safes on the market before, but Identilock is one of less than a handful of biometric trigger locks currently available.

The Identilock allows you to get a fairly natural drawing grip on the gun while actuating the lock.

The Identilock has a clamshell-type design that closes over the entire trigger area (though the slide and magazine can still be manipulated). This makes it very difficult to pry open.

It is made of high-strength polycarbonate and has a fingerprint scanner on the right side that can be used while gripping the gun.

The position of the fingerprint scanner obviously means that Identilock is not as lefty-friendly. Still, the device unlocks much faster than traditional locks, so you’re still saving time.

Identilock opens in about 300 milliseconds, which is quite literally about the blink of an eye.

Identilock can store up to three prints and will read those three prints from any angle on the scanner as long as the saved portion of the print is on the pad.

Identilock Backup Key
Mechanical Backup Using Dimpled Key

The device has a six-month battery life and charges via a USB-C port. In the event that the battery dies, an included dimpled key that is difficult to replicate can be used as a mechanical override.

Because the Identilock covers the entire trigger area, it doesn’t offer the same versatility as traditional trigger locks. The Identilock is available in five different models, each of which only works on specific handguns.

Final Thoughts

At the time of writing, there had already been 1,290 unintentional shootings in the United States since the beginning of 2022.

Safe, secure gun storage is essential in preventing these shootings and an inherent responsibility that goes along with firearm ownership.  

Okay, this is probably overkill.

Locking up your guns with trigger locks and other gun locks, cases, and safes is a large part of meeting that responsibility.

    Are any of these more or less universal, given the differences in trigger guards? I'm interested in getting them for my Ruger Blackhawk and my Uberti 1873 SAA clone.

    Personally, I'd got for a metal keyed trigger lock. I can feel a key hole and key in the dark and make them work, but combination numbers I can't see in the dark. A biometric trigger lock...uggggh had my experience with one of those - don't hate them and it worked most of the time but there was one time when it didn't and if that were to happen again it may turn out to be the one time I need it to unlock in an emergency.
