The only "jam" I ever had with my old '97 was similar to this;- IN A MATCH! I looked up, and couldn't figure out what happened. I studied the breach from a jaw-dropped, eye-glazed position, but then noticed that the lug at the back of the bolt seemed to stand out a bit. I reached up and thumbed it forward, flush with the rear of the bolt;... And it started working again!
It never happened again, as I realized that the slide must be operated with authority.
