This may be controversial, but:
I'd recommend something else. The PP/PPK design was fine for its time, but its time was a long time ago. The guns are hard to cycle (heavy recoil springs to accommodate blowback operation), marginal triggers, usually quite effective bite at the thumb joint, safety that is difficult to use, a de-cocking system that gives me the willies, and performance that pales when compared, for instance, to a SIG P239.
