I may have had a misfire at the range yesterday, and I was a bone head I may have had the safety on, But I fussed with it afterwards and are not sure if the safety was on or not, but if I didn't I would like to know if the firing pin is functioning properly. Is there some way to check it? I know with pistols I can usually put a pencil eraser end in first and it will pop out when the firing pin goes off..
Any Ideas for checking it?
Thank you in advance!
