I have shot this particular weapon. Walther P.38 code AC 42.
Function with commercial FMJ was flawless. Sights are not very good for speed or precision, which is typical of ALL service handguns of the era.
SA trigger pull was poor/fair, DA was worse, although not quite as heavy feeling as a Webley or Nagant.
Accuracy was good enough for minute of man at short range, I've never bothered to shoot that one for group size on paper, and have no idea what it might do with tuned ammo and careful shooting.
If you shoot a P.38 regularly, you can expect (eventually) the following...
The failures mentioned can, and have happened, sometimes much earlier than expected. The P.38 is no different in this than many guns, shoot them ENOUGH and something will break.]
On the other hand, who can say how much is enough? Late war production guns are more suspect, fit and particularly finish are noticeably poor compared to earlier guns.
In the 70s, Shooting Times magazine did an 11,000 rnd torture test, with an aluminum frame P.38 and an aluminum frame S&W. 5,500 rnds per gun. Guns were stripped and checked before, and after. The only thing found was finish wear on the moving parts.
So sure, it will probably break something if you shoot it enough, but enough ought to be multiple thousands of rounds if the gun is in good shape to begin with.
Just out of curiosity, did any of your google research mention the fact that the P.38 ejects
to the left??? Despite tons of reading (over decades) on my part, this small fact was unknown to me, until I got a P.38.
