There are a few additional bits of advice when pinning without washers - although they obviously don't apply to a situation of tightening loose scales unless you want to go to the trouble of removing the existing pin.

Firstly the pin hole can be chamfered slightly to accomodate the peen. Neil Miller even considers a method of tapering the pin hole in order to take up any potential bulge in the rod.

A few people recommend annealing the very tip of the pin - when cut to size, so that it's easier to peen.

It's a difficult decision when you have loose scales - on the one hand it does make stropping very difficult, but there is the added risk you run when tightening them. Personally, I've always gone the route of tightening - but not as far as I would with less valuable material.
