The majority of P38 grips were produced by AEG. Externally and internally, they had the typical design of the so-called military-styled ribbed P38 grips. On the outside, they have the same structure as the 2nd variation Walther grips, with six groves broken by the grip screw. The top one is relatively short. The left grip shows, in the lower rear portion, a rectangular indent with a cut for the lanyard loop.
The variation up to mid-1943 had three circles on the inside. The upper one had the MPBD marking, with the company code 38 and the compounds classification marking Z3. The second circle is always blank. The lowest circle contains a typical marking that we find only on AEG grips: The left grip is marked with P 1529 and a digit between 1 and 9 beneath. The right grip is marked with P 1528 and a digit between 1 and 9. It is most likely that the notations P 1528/1529 are names for specific parts given by AEG, and the digits 1-9 may represent the positions in the mold (we assume that multiple grips were manufactured in the same mold at a time.)
Grips produced since the beginning of 1943 are found with a strongly changed MPBD marking in the upper circle. In these grips, the markings were often not identifiable. But we know for certain that these are AEG grips because on some of them, the company marking 38 is still visible, and the markings in the lower circle (P 1528/29, which we only find in AEG grips) are still sharp.
These grips are found on P38 pistols from Walther and Mauser, as well as on the early Spreewek P38s. AEG grips appeared for the first time on Walther P38s at the end of the 4th variation 0-series. The Walther firm marked those grips with the last three digits of the serial number; additionally, they were marked the Waffenamt E/359. With regard to the serial numbers, that continued with the P38 variations – 480, ac-no-date, ac40 added, ac40 standard, and ac41 up to about the mid b-block, and in regard to the Waffenamt, that continued until about the early ac42 variation. Beginning from about mid-1942, we can see mainly the typical early AEG grips without the serial number and Waffenamt on Walther P38 pistols. After that, sporadically, AEG grips with 38/Z3 and two lower empty circles were found.
The Mauser P38 pistols, for the first year and a half until approximately mid-1944, were equipped mostly with the typical early AEG grips. Grips on Mauser P38s never contained a Waffenamt. The first 20,000 Spreewerk P.38 pistols featured AEG grips, which were shipped from Walther to the Spreewerk factory. After that, those grips vanished from the Spreewerk P.38s.
