A safety indicator device for a firearm in conjunction with an energy absorbing device, for enabling hammer spring tension to be relieved without damage to the firing pin of the gun, comprising a generally cylindrical housing member approximately the size of a shotgun shell or a cartridge. In the end of the housing member opposite the primer end is a weighted member secured to the housing by a lanyard longer than the gun barrel, which weighted member can be dropped through the barrel immediately prior to inserting the housing member into the breech of the gun, to indicate that the gun is unloaded. Then, after the housing member has been inserted into the breech and the breech closed, the trigger of the gun can be pulled without possible damage to the firing pin, due to the inclusion of a nylon member in the housing, in place of the conventional primer, or any metallic spring device to absorb energy. This nylon member is mounted in a generally cylindrical insert, preferably of elastomeric material, which is firmly disposed in the housing member, which insert can deflect longitudinally to absorb energy when the nylon member is struck by the firing pin.

An energy-absorbing device for use in a shotgun, rifle, pistol, or other gun equipped with a barrel having a bore therein, a breech, a hammer spring, a firing pin and a trigger, said device enabling the tension on the hammer spring of the gun to be relieved without damage to the firing pin, said dev
An energy-absorbing device for use in a shotgun, rifle, pistol, or other gun equipped with a barrel having a bore therein, a breech, a hammer spring, a firing pin and a trigger, said device enabling the tension on the hammer spring of the gun to be relieved without damage to the firing pin, said device comprising a generally cylindrical housing member approximately the size of the corresponding shotgun shell or cartridge, said housing having at the end corresponding to the primer, a hole having cylindrical sides and a substantial depth, a generally cylindrical insert of elastomeric material arranged to fit tightly in said hole, said elastomeric insert being equipped with a central aperture, a non-metallic central member of a size closely approximating the length and diameter of said central aperture, being disposed in said central aperture, with one end being approximately flush with said end of said housing member, thus to place said one end of said central member approximately in the position of the primer of a shell or cartridge, whereby upon said device being placed in the breech of the gun and the trigger pulled, the firing pin impacts said one end of said central member, causing the latter member to move longitudinally, with said elastomeric insert acting as a non-metallic type of spring member, such that the interaction of said central member and elastomeric insert serves to safely dissipate the energy of the firing pin of the gun during the dry firing thereof, the central aperture of said elastomeric insert being of a depth less than the length of said elastomeric insert, thus to create a bottom portion that is contacted by the other end of said central member.
