What size bit needed to drill rear hole in grip frame to fit a classic RT?

Hey guys, I'm curious, what size drill bit is required to drill out the rear hole to fit the classic RT banjo screw? And is this doable with a hand drill in the back yard or would I need more robust equipment?

Drill T (.358")
Good luck, I hope you don't ruin your frame.

If your doing it with a hand drill send it to someone that can guarantee it’s at least straight. I have a y grip on my bench I need to repair and I have seen several others that were messed up aswell.
