I own an 06/73. I purchased it new to use as a shooter. It looks wonderful, but had a few "quirks". I had to do a bit of "tuning", but now have it running very well. I want all of my Lugers to run as reliably as possible, so I take them on as a challenge and strive for perfection, knowing full well that I may never achieve it.
My Mauser Parabellum was not nearly the challenge of my numbers matching 1921 Alphabet Luger......it nearly drove me crazy(not a long drive for me).
