Most german officers I recall were allowed to privately purchase their "carry" sidearms. For example Hans Ulrich Rudel carried a pathetic 25 automatic which he tossed when he had to escape russians on foot.
Many of the REMF types in german forces , especially polizei preferred the 7,65 ( 32 ACP ) pistols as they were small , light and generally did the job intended of them for their purposes.
While the germans did utilze some 9mm Kurz ( 380 auto ) calibered pistols it was not in large numbers irregardless of make of pistol. Few M34 Beretta, Cz24 , M1922 browing , Walther , Ortgies , etc etc , have turned up in 380 caliber with WaA proofs or bonafide obvious useage by the german forces.
The standard issue pistol to troops was of 9x19 caliber. These ranged from the P08, P38, Radom , GP35 , Astra and some similar converted to 9x19 caliber foriegn pistols.
As well the germans utilized most every captured pistol type they had sufficient quantities of for their purposes to even include french M35 and M1892 pistols for example.
