My father has a 22 short, that has a pull safety at the back of the bolt! (you could call it cocking the rifle) when you slap the side of the gun it'll go off(making it unsafe) NO at present I do not know the brand name or much as I have not seen this rifle since I was about 15 yrs old (near 40 yrs) I know it is still in his closet, but would like to know if anybody has an Idea of what I am talking about and/or knows anything about this type of safety?
