O'neal, that was very observant of you. I did look at my other PPk . Its 7.65 mm and its mag well is not notched. So I don't know. I looked online, the few pics of older 9mm KURZ PPK's that I found, have the magazine release at the bottom of the mag well, this one has a button like the regular PPK's. So I don't know, still confused to whether this is a real .380 frame or one that someone Frankensteined. Any help would be appreciated if anyone of you might know any more info. Thanks!
