New Luger

[Hay]

I just bought a 1938 S/42. In fact this is my first handgun. I bought it with the idea of shooting it at the range a few times a year and picked this one because I have always been intrigued by the Luger and wanted something with some history as well.

I got mixed inputs at the gun shop about actually shooting it because it is in good condition and has matching numbers. Their concern was that by shooting it parts may need to be replaced and it would loose value. I do want one that I can shoot several times a year and at least now feel like loss of value is not a major concern.

My questions are:
1)Should I expect to have to replace parts over the next couple of years?

2) What precautions should I take to minimize damage to it?

3) Are there places that can service the gun and get parts if it malfunctions in most major cities or do I need to learn how to do it myself? If so how do I start?
