If you are into the history of such things, as noted the pistol is unit marked to the 178th Infantry Regiment. The 178th was a regiment in the German 123rd Infantry Division. The link below is their main story as far as what the unit did. It appears they were pretty much on the Western Front. Check out the link, it helps tell the story.
