1938 S-42 questions.

I believe that the barrel may be off an early commercial Luger, and have seen that crown/RC symbol on my own Erfurt from 1917. This "Revisions Commission" re-evaluated lugers and parts that failed initial inspection - usually for non mechanical (finish) issues.

There are a couple of different recoil springs used in Lugers. The WW-I guns used a spring with fewer turns than are commonly used with the later Mausers. I believe it's 18 turns for the older guns, and 20 for the later ones.

This and the cartridge (weight of the bullet 124gn versus 115gn, and powder charge) can affect the timing of a Luger.

While John's observation is most likely, if a firm grip doesn't resolve the problem you might look in these areas.
