I see so many stories like this and it really makes me wonder how do you not check your bag before you pack it?
Or, as others have said, use a completely different bag?
The closest I've ever come to something like this.

This is a magazine pouch. I use it to carry my multi-tool in.

One morning as I was getting ready to go to work I put the multi-tool pouch on my belt and went off to work. It happened to be an unarmed assignment. At some point during the day I want to pull out my multi-tool in front of a client employee and I popped open the pouch and pulled out a magazine.
That went over like a fart in church.
ETA After that I bought a DIFFERENT magazine holder and I never carried a magazine in one of those pouches again.

FWIW if you happen to own a multi-tool, Gerbers especially are known for wearing out their pouches. That is a Bianchi single magazine, double stack magazine pouch. I bought it for $20 almost 20 years ago and it's still in fine shape.
