I make my own pillars and use a counter bore with interchangeable pilots to open the screw holes The pilots are sized to follow the original holes. When I make the pillars they're drilled out for a snug screw shank fit , attached to the action with screws then glued in using Devcon PS putty. That eliminates any screw to action alignment issues. The final step, I'll open the holes for screw shank clearance.

Like Charles, I make escutcheons, but generally out of SS, Aluminum or blued steel. I'll stop the front pillar short so the escutcheon sets flat and makes full contact on it. After the escutcheon is fitted I'll counter bore it for the screw to action length . The rear pillar is fitted flush to the trigger guard inlet.
