Bakelite Grip Crack

[ReneC]

Hello,
I wanted to see if anyone would please give me some advice on one of my Luger Bakelite grips that has a crack on the inside of the grip that does not show on the outside. I don’t shoot it but I’m still worried that with time and handling the crack will get worse.
My question is should I attempt to repair it by adding some glue to the inside of the crack in hopes of stopping any further damage or just leave it alone and hope it doesn’t get any worse.
Any advice would be greatly appreciated.
