Abstract:
A safety device for temporarily disabling a firearm comprising:a locking member configured and dimensioned to be inserted within both a barrel and firing chamber of the firearm, the locking member having an adjustable length and including:a) an outer sleeve configured and dimensioned to be at least partially insertable within the barrel of the firearm and including a first end having a cavity formed therein and a second end expandable in a first direction and including an opening accessible through the barrel of the firearm;b) an inner rod having a first end configured and dimensioned to be at least partially insertable within the firing chamber and a second end configured and dimensioned to be at least partially insertable within the cavity of the outer sleeve;c) a spring configured and dimensioned to be at least partially insertable within the cavity of the outer sleeve, between the second end of the inner rod and the outer sleeve so as to bias the inner rod in an outward direction;d) an expansion member configured and dimensioned to be received within the opening in the second end of the sleeve, wherein insertion of the expansion member within the opening in the sleeve expands the second end of the sleeve in a first direction until the sleeve frictionally engages an inner surface of the barrel so as to secure the locking member therein such that the firearm cannot be loaded or fired; andwherein the overall length of the locking member can be adjusted by moving the rod and sleeve relative to each other against the biasing force of the spring such that the overall length of the locking member can be adjusted and locked at different lengths so as to fit into the barrel and firing chamber of different type firearms, and wherein the safety device does not extend from within the firearm so as to be resistant to tampering.
