Independent Claim
104 words
A self ejecting safety device, for use with a gun having a firing pin, a firing pin stop and an external hammer, anD, which, in safety position, renders a loaded gun harmless, by holding said hammer out of contact with the firing pin of said gun, said safety device comprising: A. a blocking member, 1. said blocking member, when in safety position, fitting between said hammer and said firing pin and being held in safety position adjacent to said firing pin by the pressure of said hammer; and, B. self - ejection means for ejection of said device when said hammer is pulled back.
Claim 2
Dependent Claim
104 words
A self ejecting safety device, for use with a gun having a firing pin, a firing pin stop and an external hammer, anD, which, in safety position, renders a loaded gun harmless, by holding said hammer out of contact with the firing pin of said gun, said safety device comprising: A. a blocking member, 1. said blocking member, when in safety position, fitting between said hammer and said firing pin and being held in safety position adjacent to said firing pin by the pressure of said hammer; and, B. self - ejection means for ejection of said device when said hammer is pulled back.
Claim 3
Dependent Claim
