First of all, $30 is a good deal for the magazines, they usually run at that price or more.
Now the differences between the P38 and P1 are these..
- P38 has a steel frame, the P1 has an alloy frame
- The P38 has nazi markings, the P1 has commercial markings
- The P38 was manufactured between 1938 and 1945, The P1 was manufactured from 1946 to 1981
Hope I helped, if you got the real P38 then you got an excellent deal. If you can't find the difference with the info I gave you then take it to a trusted gunsmith or historian. Good luck!
