Laser Ammo has developed 12 and 20 gauge shotgun capsule adaptors. The 9mm (9x19) SureStrike™ laser cartridge is fitted into the detachable capsule fore end, which is screwed shut with the end cap. The capsule is then inserted into the chamber of a shotgun.
This feature is especially convenient for police officers, who can use the same laser bullet to train with both their service pistol and shotgun.
