Staking it in place is not a bad idea, and is definitely one of those quick DIY procedures that anyone can perform which will only make your weapon that much more reliable and will definitely eliminate that possibility.
Epoxy might work as well, but I would be concerned with the chances of it eventually breaking loose or not bonding well to the buffer. I think mechanically fixing the roll pin in place through staking would be the way to go and would be more of a permanent fix.
I may have to give a go at this, and if I do, I’ll post the results with pics.
