I have one of the newer PPK/s .22s as well. It is a good little gun and shoots well. Yep, they can be picky about ammo and the DA trigger is kind of heavy. But the darned thing is a lot of fun. Oddly enough, mine has a real liking for the cheap Remington Thunder Bolts.
I picked mine up used and pretty cheap a couple of years ago. I sorta have a thing for the Walther PP series pistols.
