1939 S/42 9mm Luger

[wawebb]

My father captured this Luger during WWII and brought it back from northern Italy in 1945. There is some holster wear, but the numbers match and it cycles well. I believe that all parts, including the grips and the holster, are original.

I would appreciate any help in understanding the markings (type of Luger, where made, anything else), whether it would be a mistake to fire it on a range with modern FMJ ammunition, and any thoughts as to its value.

Thanks for any help.
