I finally got around to some careful bench shooting with my P08 and two different kinds of ammo, and concluded that the sights are off a bit. Using the standard sight picture (#1 at http://www.lonesentry.com/manuals/german-infantry-weapons/luger-pistol.html), the pattern is 1.5 degrees to the left and 1 degree high, at 10 yards. The elevation offset would improve at longer distances, and I could compensate by using sight picture #6 at closer distances, but the windage is off.
The rear sight is fixed, but the front sight is adjustable for windage. Any suggestions on how to do this without buying a special tool? I found this, http://cmrfirearms.com/shop/images/P08 Luger Front Sight Adjusting Tool.jpg, but it doesn't make sense to find and buy such a tool for a one-time adjustment of one gun. I was thinking maybe using an old micrometer I have, but I'd have to kluge up some kind of fixturing.
