Doubs,
You are so lucky to have a Luger that was owned by your father. I do not have that inheritance, but my dad took me to buy my first Luger. It has long since gone the way of trades that I wish I could take back, but the memories remain.
I have a hard time picking out my favorite Luger since all early Lugers possess a quality that surpass most (I almost said "any") modern day firearm. All grip safety Lugers are of special interest to me, so I guess my favorite would be the 1902 "Fat Barrel" American Eagle, but it is followed very closely by the 1900 US Test American Eagle, the 1902 Carbine, the early 1900 Swiss with unrelieved frame and flat button magazine, and the 1908 Luger in all its variations...etc, etc.
I am far too fond of all early Lugers to narrow down my favorites, so I guess I have to be like tacfoley and say that any Luger that goes BANG is my favorite...just as long as it was not made after 1918.
