The stop assembly has a locking position and an unlocking position. In the locking position, a portion of the stop assembly extends a distance from an outer peripheral surface of the tube assembly for engaging a portion of the firearm and preventing removal of the tube assembly from the barrel and the cartridge chamber. A plunger is disposed in the tube assembly. One end of the plunger is engageable with the stop assembly for moving the stop assembly to the unlocked position. A blocking device is disposed in the tube assembly for preventing the plunger from engaging the stop assembly and moving the stop assembly to the unlocked position. In one form, the safety device includes a combination lock assembly for removing the blocking device from the plunger and permitting the plunger to engage the stop assembly for moving the stop assembly to the locking position.
