A blasting cap initiator system has a main housing with an imperforate lower wall, parallel side walls, and front and rear walls. An L-shaped locking slot is formed centrally in one side wall with a trigger recess formed in the top wall adjacent the rear wall and a cylindrical bore extending from the rear wall through the front wall. A firing pin is mounted for reciprocal movement within the bore between a retracted orientation and an advanced orientation. The firing pin has a centrally located circumferential groove. A trigger is pivotably mounted in the trigger recesses movable between a locking orientation with a finger engageable with the groove and a raised orientation to a disengage orientation. A pair of axial coil springs between the rear wall and the cylinders independently allow the advancement of the cylinders.
