PPK/S is the 1968 "Sport" version with a longer grip. The top strap is cut with a wave to reduce glare and rear slide serrations make for non-slip grip and classic Walther styling. The internal slide stop reduces external snags. It has fixed steel sights and classic Walther checkered grip panels. The double action trigger of the PPK/S 22 has a 17.5 lb. pull while the single action has a 6.6 lb. pull. The beaver tail and magazine finger extensions improve shooting comfort.
