I have had a question in my mind for a while, but not quite the answer as of yet, maybe you guys can come up with a better answer. Is there any difference in quality and performance of Lugers from WWI and WWII productions? Are they all the same or is there any real difference between them? I have been pondering on getting one, but I like to be as well informed as I can be before going forward with any gun purchase. Thank you in advance, I will appreciate any and all info I can get.
