That's great, you have a good pistol and ability too.
I do believe you could have written the same story about many lugers, more so the commercial models, as they are really fit and finished finer than the military models. Your assessment of the P 38 matches my own.
For sure the Swiss knew what they were doing with the 7,65 cartridge- they didn't fool with the 9mm, but stuck with the .30.
The safety/sear arrangement, as you point out, is a very robust system. I have no doubt it would pass any drop test.
I would not call it "ancient" though.
