I've had several HSc's and currently have a French one (assembled from parts found at Oberndorf when France took over the occupation of that zone). All worked fine, but I never fed them soft nose or HPs; most of my shooting was with cast bullet handloads.

Alex Seidel said that getting around the Walther patents was difficult. Probbly this explains why the double action pull is so stiff on these guns. The single action pull is just fine.

I shot a friend's 380 HSc. For the more powerful caliber they put a recoil spring in there that almost defies human strength to cycle the slide for the first round.

Which reminds me: like the previous Mauser pocket pistols, they stay open when the last round is fired, and then shut with a slam when you insert a new magazine. Be careful your finger isn't on the trigger, as it's easy to let one go then accidentally.
