My 1938 S/42,

Congrats on purchasing a Luger that runs 100% on 2 different brands of factory ammo. That is not always the case. When you break it down for cleaning take a good look at the hold-open part/area, and spring. Also, you should clean the mags real well, if you have not done that. Again, you did good for your first Luger purchase.
