Some times when I am shooting my 1911 the slide will not slide back forward all the way; it will stop about ¼ inch short, which will cause the gun not to shoot. If you then pull the slide back an inch it will return to normal and will be able to shoot. This problem does not occur after every shot, but it does happen pretty often.
It has been working fine and just started doing this. I don’t know what is wrong with it.
