Walther PPK/S Misfire – Additional Work Performed
Hello All. Sorry for the long absence. Been busy with the family and all that goes with it.
It has been asked how the spring repairs went and did they solve the misfire issue in totality. The repairs went very well and were accomplished rather quickly. The firing pin spring replacement did work as the indicator now functioned properly. However, I was still having problems with the Walther PPK/S misfiring.
Frustrated by the lack of success, I took a good look at the Walther PPK/S when firing. It turns out that the slide would slightly rub the tops of the custom wood grips installed on the gun. This rubbing would then cause the safety to release while firing.
In order to rectify this issue I decided to hone the bottom of the slide and simultaneously sand down the wood grips, paying special attention to the grip cut-out near the safety release. The slide was honed on a stone with some oil. This was done slowly by hand as only a slight bit was needed to be removed.
The wood grips were then sanded with a file on the tops and the section around the safety release button was sanded down with a round file to open the area around the safety release button up a bit more. This was also slowly carried out with a hand file.
The results were good and I now question the worth of custom made grips.  I like the feel of the wood grips, but may buy Walther factory produced custom grips in the future to avoid any issues.
