Abstract: A safety bolt and less lethal ammunition system for use with a firearm, such as a shotgun, is provided. The system includes a safety bolt operatively coupled within the shotgun. The safety bolt has a bolt head with a recessed bolt-face and a firing pin. The firing pin does not extend beyond an end surface of the bolt head during operation of the firing pin. The system further includes a less lethal round loaded within the firearm, such as a shotgun, wherein the less lethal shotgun round includes a case-head having a protrusion extending therefrom and a primer on the protrusion. The protrusion corresponds with the recessed bolt-face of the safety bolt. The firing pin engages the primer when the protrusion of the case head is received within the recessed bolt-face. The firing pin cannot engage the primer of a lethal round because of the recessed bolt.
