The sense 'detonating a percussion cap' is a domain-specific application of 'strike' leading to ignition, which may not be obvious to learners without knowledge of firearms/explosives.

Etymology

Percussion comes from an old Latin word percutere, which means 'to strike' or 'to hit'. In firearms, percussion refers to the striking action that makes a cap or primer set off the powder, so the word matches the action that causes the gun to fire.
