Rear Sight on Benelli M3 Super 90

[SoCal Shooter]

I recently acquired an this M3 and after about 50 shots the rear sight came off. I tried screwing it back in but I guess the threads are stripped. I was thinking about using Loctite. Any suggestions?

Thanks,

Sean

I have the M1 Super 90 with the ghost ring rear sight. Mine was always coming loose and finally disappeared altogether during a match. I got a new one and secured it with Loctite. Been fine since.
