Just curious, has anyone else owned a P-4 Walther?
I bought two that were probably new in the box in the late 1980's when the police surplus guns were sold.
They came in a new Walther box with a used holster.
The P4 was a "stop gap" design done by Walther to give the German police a better gun then the P-38, until they could get their new P88 design finished.
What they did was modify the P-38 slide to eliminate the top cover and loaded chamber indicator pin.
The hammer had a hole in the face that fit over the firing pin so it could not contact the firing pin until the trigger was pulled, which lifted the firing pin up where the hammer could strike it.
The safety was simply fitted with a spring that snapped it back up when pushed down. This served as as a decocker.
The P4 was a measurably better gun then the P-38, eliminating the top cover loss problem and any risk of firing when the safety was applied and the hammer dropped.
Wish I had kept at least one of them.
