Hello, I am new to this forum, I have a .30 Luger, that I have inherited from my Grandfather, that he brought back from overseas. I was wandering what it is. I will try to explain it best as I can...Overall dimensions are 8.25" long, from tip of barrell to where it enters the frame is 3", numbers are the same stamped on everything, but the magazine, Saftey is stamped gesichert, front of frame is 20** Germany, and a M below that. It looks like a little crown stamp above a N. and when loaded GELADEN is up on the extractor. Bottom of the clip is stamped S/42. I just finally found some ammo for this, and it shoots pretty sweet. Thanks for the help, and looking forward to hearing from you all...Also, I have I believe another .30, and 2 9mm's. once I can get this IDed than I will post about the others.Thanks...-Joshua
