In my experience, I have not seen grip wear that I would/could attribute to holster wear. I think several factors contributed to the extent and nature of wear on a Luger (or any pistol) from the holster, not the least of which was the amount of time carried in one. Other things to consider is that any pistol/holster used in Europe (and I know most of Russia) spent a great deal of time WET from rain! There is no practical way to avoid this and in my experience it can spend several days at a time in a soaked holster. Also you may have noticed that many Luger holsters have a small amount of paper or cloth stuffed in the tip where the muzzel rest. One purpose this served was to make the Luger ride a little higher in the holster...Perhaps makeing it a bit easier to extract even with the pull up strap, this also maintained the shape of the barrel area of the holster and I would bet caused less rubbing, although I doubt the German soldier/officer realized this or even cared. I think that the nature of service had a great deal of impact on the wear, soldiers marching, horse riding or traveling in armored vehicles were/are subjected to constant pounding and vibration that would cause a pistol to slightly be rubbing against the holster. I think that a Luger with really worn grips was carried in the hand a lot or perhaps fired a lot like a training weapon. The ones that show true period wear like this really talk to you.
