Canadian Restricted and Non-Restricted Firearm Safety (CRFSC) Practice Exam

A trigger block safety, also known as a trigger lock safety, is designed to prevent the trigger from being pulled unless intentionally disengaged. This type of safety mechanism ensures that the firearm cannot accidentally discharge. It is crucial in promoting safe handling practices, especially when the firearm is not in use.

The term "lever safety" aligns with this concept because it refers to a mechanical device that must be moved or manipulated (often in the form of a lever) to allow the trigger to be pulled, thereby blocking any unintended actions. This mechanism is an important feature in many modern firearms, enhancing safety by preventing accidental discharge when the gun is dropped or when it is being handled improperly.

In contrast, the other terms refer to different safety mechanisms or aspects of firearm operation. For instance, grip safeties require the shooter to maintain a specific grip on the firearm for it to fire, whereas half cock safeties typically relate to single-action mechanisms where the hammer is positioned in a partially cocked state for safe de-cocking. Drop safety mechanisms prevent the gun from firing if dropped. Each of these options serves to enhance safety but is distinct in its operation and function, which is why they do not equate to a trigger block safety.
