The present invention entails a safe weapons system for a firearm. In particular, the safety system of the present invention comprises a non-fireable slug specifically designed to be received and accepted within a firing chamber forming a part of the firearm. The non-fireable slug includes an outer cylindrical tapered wall that is generally tapered to conform to the taper of the firing chamber itself and the slug is specifically sized such that it is designed to assume to seized or secured position within the firing chamber intermediately between opposed end portions of the firing chamber. Safety is realized because of the position occupied by the slug within the firing chamber. The position occupied by the slug within the firing chamber makes it practically impossible for the firearm to be chambered with a live ammunition round.
