A buddy of mine has one of these, also with the Hogue grips, which I got to shoot side-by-side with my stainless PPK. The two are nearly identical in size and weight, with the SIG being slightly thicker. The trigger pull in both DA and SA were also very close in comparison. I noticed that the PPK gives a sharper "sting" to the web of the hand while firing, but the difference may have been the grips. The PPK had the stock plastic ones. I didn't fire the SIG with the OEM grips. Design is very similar between the two and both are very accurate because of the fixed barrels. I like the PPK slightly better because the mag release is in a familiar place for us Americans, but they're both excellent guns of proven quality and reliable designs. The prices are also very competitive. Either would be a good choice for a carry piece.
