Mauser HSc's generally are nicer to the web between your thumb and index finger than a Walther PP/PPk.
I certainly didn't find it so. Quite the contrary in fact. Like you, I found a 60's vintage, Interarms imported one in .380ACP (or (9mm kurz, if you like). As I had always wanted one (they
are gorgeous pistols), I snatched it up. I was instantly disappointed with how the gun felt in my hand, but I bought it anyway since, as I said, I had wanted one for many years. The hammer is mounted very low in the frame, which results in the gun pointing rather low, at least for me. The gun's also
very thick in cross section for a weapon that was originally designed as a .32 pocket pistol. It looks like it would be extremely ergonomic, but it doesn't feel that way (now the Remington Model 51 I own... ah, now that's another story altogether; there's a .380 that feels every bit as ergonomic as it looks).
I took it to the range that same day. It drew blood with the first round. That very low mounted hammer again. And worse still, I couldn't fire a full magazine through the thing without one to two stoppages. Not once during the entire session. And I was shooting FMJ. I took the gun apart and lubricated the slide rails, then put it back together. No difference. I don't think it was the magazine either, as I had two with the gun, neither of which appeared to be damaged in any way, and the gun performed equally unreliably with either of them. Perhaps the problem was a weak recoil spring or something that could have been fixed, but given how disappointed I was at its ergonomics, and how it bit my hand so badly, I wasn't about to put any money in it. I put it in the local trading post the same day and said goodbye to it with no regrets.
