Hello, I’m new in the forum, reading the posts here I already learned a lot about Luger pistols. I’m looking for more information about my Luger 1911 DWM, S/N 8000, all matching numbers but the magazine. It has an R on the outside of the grip and Ritter written on the inside of the grip, (matching to the gun). Any information you might have will be appreciated. Thanks in advance !
