Piet,

Here are two extracts fromt the military Luger Blueprints from 1913:

The standar bore diameter is 8.85mm (land to land)
The standard groove diameter is 9.1mm (groove to groove)

manufacturing tolerance is + 0.01mm
or -0.03mm

A CD of very clear images of all the blueprints and including some great bonus drawings is available for purchase in the "For Sale" forum... see the "sticky" post near the top of that page...
