Firearms are complex machines with multiple parts moving at high velocity under heat, friction, and stress. As a result, firearms can experience mechanical malfunctions for various reasons, from fouling and a lack of lubrication to parts breaking.
What is a Misfire?
A misfire occurs when the firing pin or striker fails to detonate the primer or the primer fails to ignite the propellant charge in the cartridge. Misfire is synonymous with failure to fire, and you’ll usually experience this type of malfunction as an audible click. A misfire can be caused by a defective primer or a light primer strike.
