What are the Best Trigger Locks? 8 Best Products of 2021



Amazon Disclaimer

A gun trigger lock is among the most important gun accessories you must have to secure your gun. Trigger locks are normally small devices that cover the trigger to prevent unauthorized users from firing.   They are very important if you don’t have a secure place like a gun safe or a gun cabinet for storing your guns. 

The good thing about them is that they are affordable, easy to use, and very compact. They also come with reliable locking systems which give you quick access any time you want to access them. However, you need to be careful when buying because some are more reliable than others. In this article, we shall reveal the 8 best trigger gun locks that are indeed worth your money.

What is a trigger guard lock?

Trigger locks are devices that are installed on a gun trigger guard to prevent kids or unauthorized people from accessing the trigger.  The most common ones have two pieces that fit perfectly on the trigger guard to prevent fingers from making contact with the trigger. As a result, they prevent accidents that might occur due to misuse of your firearm. Most of them are equipped with a combination lock that allows you to set a unique access code. 

Cable vs Keyed locks

Cable locks and keyed locks are the most common types of locks you can use to prevent unauthorized people from firing your gun. However, most people are not able to differentiate how the two works. Below are some of their differences.

Keyed trigger locks

These locks normally contain two halves that cover the trigger guard. Due to their design, they prevent fingers from accessing the trigger. The major benefit of these locks is that they are very easy to use and are also affordable. Apart from that, they are not easy to remove meaning that they are very secure. However, they do not fit all types of firearms. Again, you should never use them when the firearm is loaded.

Cable locks

Cable locks are designed to pass through your firearm to block the barrel which prevents firing.  They are normally covered by a safety material such as plastic, rubber, or nylon.  They are very cheap and easily accessible. 

Some are designed to prevent the insertion of magazines in rifles or pistols. This ensures that the guns are not loaded when they are stored. They are very effective in preventing kids from firing a weapon accidentally. However, they are very easy to tamper with by using a wire cutter. Again, they are not compatible with all types of firearms. 

What to look at when buying trigger locks for guns


Trigger locks are designed to fit specific types of guns. Some are suitable for handguns or small pistols while others are suitable for shotguns and long rifles. Before buying, make sure that the one you have picked is compatible with your firearm.


Some gun trigger locks are made of cheap plastic which means that they are not durable. The best ones are those that are made of zinc and steel like the Master Lock 90DSPT Gun Trigger Lock.

Locking mechanism

Trigger locks come with different locking mechanisms which include;

  • Keyed locks- These are the most common and you just need to use a key to unlock them. They are easy to use but you need to be careful not to misplace the key.
  • Combination locks- Trigger locks with a combination lock are very secure because you have to enter the correct combination to access them.  
  • Biometric trigger locks- As compared to other locking mechanisms, biometric locks provide the quickest access.  They can recognize your unique fingerprint but they can be used by several people.  Unlike others, these require batteries and they also come with backup access keys.
