We've gone over this many times, I will add my usual answer to your question. I carried a walther PPK's, German made 1976 model in 380, for 20 yrs. Mainly because they were the smallest thinnest guns in a decent "barely" "caliber" that you could find in the 70's other than a snubby, which still was wider and carried only 5 rounds.
In modern times there are too many alternatives that you can find in larger better calibers, like the XDS, which happens to be my pocket carry.
380 is ok at close range and the gun is accurate. What it is not is, reliable. If you go through the many threads on this and other forums, some ware between 30 and 50 percent of people who owned these guns had either FTF, or Stovepipes, with them. I had 2 and that was enough, both were during a combat course when I shot competitively as a younger man.
I sent the gun back to a gunsmith, who specialized in these guns, and to the factory. I never felt safe with it after that.
You will find a thread I read about a week ago on the same subject, and it was about 50/50, perhaps the sig 230 might be a better decision. The safety is just a decocker, no one walks around with a PPK or PPK's on safe, the double action is about 14 lbs., "if I remember" and the single less than half that, so it takes some time to get used to the difference.
They are very accurate because of the blowback design, and nice looking. The sights are poor, but ok for a belly gun.
I had S&W adjustable sights put on mine, it had been customized by a shop that only sold walthers, in Roslyn LI, back in the day. Nickel plated," factory", and cocobolo grips. Stunning gun. Michael Britt, was the guys name
Some say there were very few factory nickel plated guns, but this guy was a German who claimed they were done for him, so who knows, it was a great job if aftermarket.
