Based on the second Luger patent on these flute cuts in the firing pin, I don't think we agree on that. The patent expressly states:

"The purpose of the new facilities is to make it possible for the gases which have penetrated to pass through the gas paths as unhindered and rapidly as possible get behind the plate of the firing pin and into the interior of the chamber."

The "chamber" mentioned in the patent is not the one that holds the cartridge, but rather the one that holds the firing pin inside the breech block.

This would seem to describe the objective of the fluting cuts was to allow gas to escape when a primer is pierced.

How else do you read this?
