How many soldiers did carry handguns?

well lets look historically...in 1939 there were 1,500,000

whermacht german army going into poland.officers being roughly 35-almost 50 percent says at least you have 700,000 lugers right there. Most new or recent some put back into service from ww1. then you have both naval officers and sailors who carried lugerpistols. then you have the ss who from my reading carried only lugers. As you have worked on guns I have done much reading but this is a crude but probably not too innaccurate estimate.
