comments on my Navy Luger please

The holes are drilled through to the breech block chamber. They do appear to be vents. They also appear to be factory, but I'm only a novice. If it is an after factory modification, any idea if it was done in the U.S. or Europe? I have included an image with my Mauser for comparison. I wish I had my good camera. Thank you, Bernie.

Thank you for the additional photo of the breechblock. I have never seen this mod on a Luger before. There is sooooo much to learn concerning P-08s.

I thought vents holes at first too but the picture of the breachblock looks strange to me and the more I looked at it the more concern I had. It is most likely a trick of the camera but what is that groove near the top front nearest you?
interesting!
