| Walther PPK/S |
This handgun came to me from a retired police officer. He had carried it as a backup and off-duty gun for many years. At some point the gun was refinished, electroless nickel, after it was damaged. The gun had intermittently stopped firing on the first (double action) shot.

He remarked, and I agree, that this gun had one of the nicest DA trigger pulls for a Walther that we had ever seen. It was very smooth.
I detail stripped the gun and inspected every part. Nothing was out of the ordinary, except for the main spring. This is the spring that drives the hammer forward into the firing pin. I found that the main spring appeared to have been shortened. Typically, these springs are closed on both ends, while this spring was closed on only one end.
I tested the force applied to the firing pin, comparing this to other .380's I have in the shop and found this one too light. So the main spring needed replacing. Brownell's only carried Wolff springs. I called Walther USA and they shipped me a new spring. The new spring had a similar number of coils, but was longer and closed on both ends. After replacing the spring I tested again and found a significant increase in the firing pin force.
