This is the part that almost every Nerf blaster has. In some blasters, such as the Secret Strike AS-1, the trigger is unique and is not shaped like a traditional blaster trigger. Older Nerf blasters have varying trigger shapes and colors. Newer Nerf blasters from the Vortex, Dart Tag, and N-Strike series feature the same trigger on every blaster.

This trigger is only featured on blaster that use a flywheel system, because it is used to electronically power up the flywheels.
- Some electronic blasters such as the Stampede ECS, do not use flywheels and as a result, have a button, rather than a trigger, for its electronic capabilities.
