How to repair a worn driver contact?

The back of my T10 driver looks similar to this picture below, but it still works fine for now.

I have hardly used it so I think it could be a problem with if it was used often.

All I can think of is a drop of solder, any other suggestions or would that be the best way?

I would personally leave it as it is but if you want to do something then a blob of solder would work.

Lead-free solder may last a bit longer.
