Hello gunsrfun1,
there are several things to look at when separating a commercial Luger from a military one.. The easiest thing to look for, is any military markings on the right side of the barrel extension (slide). Also, military Lugers tend to have more parts stamped with the last two digits..

btw. there are some great Luger pictures in the gallery on this forum, this can be helpful to look trough.
Finding out a thing or two about Lugers, before purchasing one is always a good idea.. There is a lot of 'bad' lugers out there waiting for someone just to pick them up. Good luck!
