There is an interesting document, labeled as:
H.Dv. 242
M.Dv.Nr. 536
L. Dv.404/1

called 'Anschiessen der Handfeurwaffen und M.G. (Erdwaffen)'.

or 'Test firing of hand guns and Machine Guns (ground weapons)'.

On Page 16 it describes the procedure for the P08:

Pistols must be test fired to determine their accuracy when taken into service. Furthermore when in service a new front sight or rear toggle piece has been installed, when bad accuracy is observed or after repairs at the Heeresfeldzeugwerkstatt, also when the test firing has already been done there.

Fring will be done at 50 meters while sitting at a test firing table.

The sights may not be bare metal and must be protected from sun light.

No test firing may be done during bad weather conditions.

The shooter supports the elbows, grips the pistol grip with both hands and the bottom on a sufficiently high enough sandbag. It is to take into account that the barrel of the pistol is kept free of the sandbag. Then 5 shots are fired at the test firing target (annex 14).

The pistol succeeds when 4 out of 5 hits are inside the rectangle. If this is not the case, the test firing has to be done by another qualified shooter.

If this is also unsuccessful, the pistol is to be handed over to the Waffenmeister or Waffenfeldwebel for inspection and repair. If problems with the pistol are determined for which the Heeresfeldzeugwerkstatt is responsible, the pistol is sent there.

The results of the test firing are noted by the overseer at the target with a fountain pen on a grouping pattern (smaller test target, size 1:10), annex 15, and signed, After test firing, day, name of the test firing shooter and weapon number are recorded on the grouping pattern.

The grouping patterns are to be archived and presented during weapons inspections.

Berlin, the 18th of May, 1936.

Below are scans of the referenced targets in the text above, as well as the front and back of an original, blank, grouping pattern page as described in the HdV.
