Stair Railing Post in Sandstone

I want to install a railing going up my front porch steps. What is the best way to anchor the bottom post into a sandstone stair thread?

Using a good quality hammer drill drill the appropriate amount of holes, install lag shields and lag bolt galvanized bolts to secure the railing.

Stainless steel bolt set into a masonry-specific epoxy.
Sandstone is quite soft and holes in it are prone to start cracks/fissures. The epoxy is especially critical if it is a vertical hole (water trap).
Stainless is so there's no chance ever of rust staining, or rust expansion blowing apart the stone.
