In America you have the standard PPQ 9 mm or .40 with plastic sights and 15 or 12 rd mags. You also have the PPQ first edition, which have a factory threaded barrel and one 17 rd. mag and night sights. In Germany you have the PPQ Navy. All of these guns are designed to be fired when wet. Theres actually a special scupper hole in the striker mechanism to allow water to drain quickly.
