Assuming everything is all matching, you have an alphabet commercial Luger made sometime in the later half of the 1920’s. DWM made these pistols after WW1 because they were limited in making anything in 9mm for military use by the Versailles Treaty. Instead they refurbished old military pistols and used existing stocks of parts throughout the 20’s to assemble commercial pistols like these to stay solvent post-war before their excess Luger stocks and machinery were acquisitioned by Mauserwerke around 1929/1930. It’s a very common variation but a Luger all the same. Congrats on your new acquisition and do your best to read through the FAQ document on here and get the books or pay close attention on here for more info. Welcome to the forum!
