41 42 Code, S/N 489

[grap]

Gentlemen,

Recently, I have come into a 41 42 code with all matching serial numbers except the mags, neatly tucked in a bml/42 PO8 holster. It was carried back by Grandfather and left me by my Grandmother who recently passed. Everything I have learned about Lugers I have learned in the last 2 hours and mainly by browsing this site (quite excellent). What I am interested to know is, does the 3 digit serial number mean anything in terms of value vs. a 4 digit number, and does it mean that it was the 489th produced in that series? And also, should I even consider firing this gun (I am a bit curious to say the least) or should I just oogle over it from time to time and put it back in the safe? And if I can fire it is there a certain load I should (or shouldn't)use? Thanks in advance for time... (I have taken a picture of it and will try to forward it to somebody by email.)
