Had this happen to me many many years ago on an old J Stevens doiuble. After I got back home I put a couple of emptied in & "Slammed" the gun shut & otherwise jarred it around & could never make it fire again without pulling the trigger. The safety was an auto & working properly & no finger was on the trigger. I eventually concluded the same several here have that I had simply not opened the gun far enough & sear was barely caught. Closing the gun then jarred it off. I had not closed the gun near as hard As I did in my "Tests". From that day forward somewhere around 50+ yrs ago I have always made sure when opening a hammerless I fully open it & that both sears click in. Have never had it happen again on either that gun or any other. I do not personally feel an external hammer gun is any safe than an internal hammer gun. Both have their pluses as well as their minuses.
