Of these the only one that jams is the PP, if you feed it cheap hollowpoints.
Before 1994 the primary weapon was a Walther P1, backup #1 was a P4 - I switched because the P38 line doesn't like to feed all hollowpoints (but they do like the FL ammo - it was designed for it) and you don't always know what ammo you will be able to get.
Try the Federal 9BP 115-grain load [#16 in the display below] or the Remington 115-grain RNJHP [#4 below] for use in a P.38 or aluminum-framed P.1, long a favourite of mine, though usually taking a backseat to the Browning GP I've carried and used since 1969. You'll likely find that it's not the hollowpoint configuration itself, but the overall length of the loaded round, that's critical in feeding in a P.38 or PP, and a PPK is even fussier, possibly because of the greater magazine spring pressure from its 1-round-shorter magazine.
I had a little PP in 7,65 that was one of the most accurate of it's breed I've ever had, and let it go to a fellow newspaperman facing death threats, who practiced and practiced with it and became extremely good with it, the only firearm he owned at the time. At least it went to good hands, but I've often wondered if it had been tuned, and if so, by whom and using what methods. I replaced it for my own purposes with another plain-jane Makarov, whose safety at least works the way I prefer.
