"Danish police PPs:
After forty and sometimes more years of service and presumably due to the use of a more powerful ammunition, some “Rigspolitiet” PPs and PPKs showed cracks in the slide. After a team from Walther/Ulm had inspected these pistols, there was an agreement in 1988:
Walther/Ulm provided 1500 reinforced replacement slides. Basically these slides were not reinforced, however, by adding any reinforcing material. There were simply some steps in production omitted, which weakened the slides. The signal pin as a loaded chamber indicator was eliminated. So the underside of the slide does not have to be milled through to give access to this pin. This underside remains massive and works as a cover for the firing pin (cf. PPs and PPKs in caliber .22 l.r.). A round firing pin (standard in series production from 1971/72) was used. So a cylindrical bore from the rear of the slide sufficed.
These replacement slides have the new box-shaped rear sights and the new, thicker and longer front sights. The slides were proofed by the Ulm proof house in 1988 and have the appropriate proof marks: “Federal Eagle over N”, “antler” (for Ulm proof house) and the year code “JJ” for 1988."
