I own a PPKs, a PPK and an HSC, I've never shot the PPK but have shot the PPKs many times. The first time I shot it it made red scratch marks on my right hand, I carefully ran the sharp edges at the lower rear area of the slide over a gray wheel (It's stainless so no damage to the finish) and though it doesn't look any different it made a huge difference.
I love the PPKs, it is a beautiful weapon, an iconic weapon and I find shooting .380 perfectly enjoyable. The HSC is also beautiful, though I've only shot a few magazines through it. The disassembly is genius except that it can be hard to pull the plug in the trigger guard down without a struggle, but the way it comes apart is magical and took a bit to get used to.
That reminds me of the C96 Broomhandle, it is very unintuitive to reassemble, the way the barrel and breech installs back into the frame, every time I do it I have to relearn it's secret, and the HSC is only slightly less so in that regard.
Of course any disassembly or assembly process gets easy with a bit of practice, except a detail disassembly of a 1903 Colt auto, you have to grow a third arm!
But back to shooting, I've never understood people saying the .380 is hard recoiling, but that's just me I guess. A lot of people say the 1911 in .45 is too much.
My pastor has a Pachmayr Dominator, which is about an 11" .308 barrel and bolt action receiver on a 1911 frame, I shot that one time and knew I'd known recoil. That same day he shot six rounds through it, and his hand was bleeding between the thumb and forefinger where the gun tried to force it's way free of his grip, now that is some recoil!
