It's the first pistol design which was DA/SA, meaning it could be fired in either double action of single action mode.

Nope. That was the earlier Walther PP of circa 1929, thepoliezipistole, usually found chambered in the 7,65mm Browning/.32 auto cartridge, though .380 and .22LR versions are pretty common.

The P.38 was indeed the first 9mm Parabellum double-action handgun to be adopted for military service. And a surprising number still soldier on here and there in odd corners of the world.
