Care to elaborate?
I was under the impression that the Walther PPK had a very good reputation, and has been produced for many years. When I get the chance to shoot one, I'd like to know what to be looking for specifically.
I found the snappy recoil to be a little uncomfortable, probably simply because of the size and blowback: at least judging by my last (and so far only) experience shooting one, I think my hand would be sore after an hour at the range. It's a testament to its charisma that I'd be tempted to try again... and probably try again until it stopped bothering me
I've also heard of, though not experienced, the 'bite'.
There's no slide lock, so there's no way to provide an obvious indicator that it's unloaded. (Of course you're going to check, but some ranges like to see the slide locked open. Nervous range assistants are no fun!) On the other hand, it should be a lot easier to take apart than a 1911 or similar...
It's a very compact gun, so I can't really blame it, but the fact that it only holds 6 shots of .380 is arguably a downside compared to, say, the mini Glocks.
To go back to your original question for a moment: I'm no expert, but you might want to try the smaller SIGs, such as the
P232, or even a really small 1911 like the
Colt Defender. If what you're feeling from the PPK is "small, well-built, metal", those should provoke the same.
