What does the term "trigger lock" refer to?

The term "trigger lock" specifically refers to a device that is designed to prevent a firearm from being fired by securing the trigger in a locked position. This mechanism is an essential safety feature that helps to ensure that firearms remain secure and non-functional when not in use, reducing the chance of accidental discharge. Trigger locks are commonly used in homes where firearms are stored, providing a critical layer of security, especially in households with children or individuals who may not be trained in gun safety.

The other options do not accurately describe what a trigger lock is. For instance, a mechanism for cleaning a firearm relates to maintenance, while gun safety rules encompass a broader range of practices aimed at ensuring safe handling and storage of firearms, rather than a specific locking mechanism. Additionally, features that improve shooting accuracy are focused on the performance of the firearm itself rather than safety mechanisms.
