Guns that were so altered were stamped with a small Erfurt inspection mark on the front sight base.

Norme , I read in some book 75 meters before 1913 and then reduce to 50 meters after
So wich is right ?

It should have been read this way:" It had come to the attention of the Gewehr-Prüfungskommission that Pistols 08 of DWM manufacture and of Erfurt production differed from each other considerably in respect of point of aim. The point blank sighting range differed between 80 and 110 m. No remedial action had been taken so far, as the G.P.K had been conducting trials to ensure that fitting of the hold-open would not affect the point of aim (Note. meaning shooting trials).Beeing satisfed of this, it suggested to the ministry of War on 24 May 1913 that on accasion of test-firing of altered pistols the point blank range should be standardized at 50 m. For this purpose, front sights of different heights wer to be used:


15.5 mm (minimum height),
15.8 mm (standard height), and

16.1 mm (maximum height),


in each case measured from the centerline of the bore. On 20 October 1913, the Gëwehr-Prüfungskommission revised their findings, the heights of front sights were now to be:


15.1 mm (minimum),
15.4 mm (standard), and
15.7 mm (maximum)" ...

Gortz & Sturgess' comments WRT sight zero can be interpreted a couple of ways. They seem to suggest that DWM zeroed their pistols for 80 meters while Erfurt zeroed for 110 meters. OR they may have meant that guns made by both would zero somewhere between 80 & 110 meters. The explanation is on page 1100 of G&S.

Regardless, the decision was made to replace the front sight blade of already issued Lugers to zero at 50 meters and newly manufactured guns would leave the factory zeroed for 50 meters. The sight change for existing guns was done in conjunction with the modification to install the hold open on those Lugers without them.
