I have heard that its safe to dry fire a Walther. Personally I dry fire mine alot, recently I aquired a CZ75B which is not safe to dry fire. I went out a bought a couple of snap caps. If your really worried about breaking the firing pin/striker, just buy a few snap caps. They run about 5 bucks a pop, or make your own snap caps. Its pretty cheap.
Hope it helps
