Lots of them, in fact this has been brought up several times, but who knows where!
There are several wide ranging books. First question, does he like a certain time period, or own a certain time period Luger?
Jan C. Still has the best books for certain eras; he has one each on; Imperial Lugers, Weimar Lugers, Axis Pistols, and Third Reich Lugers, most are available on e-bay.
On many eras, Kenyons, Lugers at Random is good.
Walters, The Luger Story is a good read, and worthwhile.
Datig and Jones are good, but out of date.
Other books I have left out are too specialized or suck.
