The S&W PPKs has a longer "beaver tail" that makes shooting it more comfortable and eliminates the "Walther bite". I often carry mine with a round in the chamber and decocked. I think it is perfectly safe and there is no point to having a double/single action auto if you don't. I had mine worked over By Cylinder and Slide. They put a Novack style rear sight which was a great improvement. If you purchase a S&W PPKs there was a recall, call S&W and they will tell you how to tell if the problem has been corrected on the gun at issue.
