The zipper on my rifle case gaped open.
I liked the case and didn't want to throw it away
so I looked at a few YouTube videos and found this silent one.
(Sound of hand slapping forehead.)
It's great! Go easy on the pliers. It doesn't take much strength.

stumbled on this fix myself, it generally fixes most issues. Thanks for posting

Nice- I have a problem zipper just like that- I will try that fix. Thanks for sharing

May have to try that. I have my Dad's Browning A5 and the zipper on the original Ted Williams lambs wool lined case messed up. It would be great to get them together again.
