January 16, 2023

Whether you have young ones around the house or just want to make your guns as safe and secure as possible, invest in trigger locks. Trigger locks are a great way to keep your gun safe, especially if you don’t have access to a safe or a gun cabinet.

How it works is that trigger locks have two pieces. Each piece sits on each side of the gun’s trigger guard. When locked, the trigger lock prevents your fingers from accessing the trigger. As a result, you won’t be able to fire a gun whenever a trigger lock is on.

In some states, trigger locks are actually required by law. Even if you do not live in an area that requires gun triggers, it’s still a great idea to invest in these locks for maximum safety. Though they aren’t always as popular as other protection methods, trigger locks are a must for any gun owner for the safest gun experience possible. 

That being said, you have to find a safe and effective gun trigger lock if you want it to work as it should. To help you out, we have made this list of the 3 best gun trigger locks. We begin by covering some important factors to look at when picking a gun trigger lock. From there, we list our recommendations based on the locking mechanism and give an overview of each one.

How To Choose The Best Gun Trigger Locks 

Whenever you are picking out a gun trigger lock, you want to choose models that fit your gun and are safe, effective, and convenient to use. After all, not all gun trigger locks are as effective as they ought to be. By considering gun trigger locks before purchase, you can find the best model for your guns.

In order to choose the best gun trigger lock, look at the size, locking mechanism, portability, and materials. These four factors will ensure you get a highly efficient and safe gun trigger lock that is also convenient for you and your gun.


The most important factor to look at when selecting a gun trigger lock is the size. Not all gun locks will work on your gun. You have to find a lock that is specifically designed for your gun type. You should easily be able to find a specially made lock if you have a common gun, such as a pistol, rifle, or shotgun. Many locks on the market can work on all the most popular guns. 

If you can find a lock that fits the exact model of your gun, even better. No matter what, make sure to read the specifications of the lock beforehand to make sure that it will actually fit around your gun’s trigger effectively.

Locking Mechanism 

Gun trigger locks can come in several different styles and locking mechanisms. There are mainly three different options: keyed locks, combination locks, and biometric locks. Here is a closer look at each one of these locking mechanisms:

  • Keyed Locks: Keyed locks come with a key. This is one of the easiest locking mechanisms because it is straightforward and easy to use. The downside is that you will have to keep up with the key. If you lose it, you won’t be able to remove the trigger lock.
  • Combination Locks: Combination locks don’t have keys. Instead, you will set a combination and rotate dials in order to unlock the firearm. This option takes away the risk of losing a key, but you will have to remember the combination.
  • Biometric Locks: Biometric locks are the easiest to open. They rely on your finger, much like a fingerprint scanner. Although this is the most convenient method, it is bulky, expensive, and runs on batteries. It’s best to select biometric locks only if you are getting a lock for your home’s self-defense gun.


More than likely, you will have to transport your gun with the trigger lock in place. So that the gun is as convenient as possible, find a trigger lock that is portable. Portable trigger locks won’t add much weight to the gun, but they will still ensure that the gun is unable to fire.


Only opt for trigger locks that are made from durable materials. The materials used are what will determine how effective and long-lasting the lock is. Always look for heavy-duty materials, such as zinc or stainless steel. There is no point in purchasing a plastic or polymer lock since these can easily be broken or compromised.
