Pete,
I recently bought a 1963 Swiss army pistol manual, which still described the Luger in detail, next to it's followup the SIG P210 / Model 1949. So I expect that although manufacture ended in 1949 the Swiss lugers enjoyed a long service life afterwards.
Had some fun with the manual at our local shooting club which is quite full of people who believe the SIG P210 is the best military pistol available. The side-by-side comparison in the Swiss manual proved the opposite, the luger performed marginally better, had a better penetration, larger sightbase and less weight
