Tim, although I've not yet observed this, I don't see why it could not happen under certain circumstances. Any mechanical force has the potential to compress wood grain/fiber, or actually shear off the subtle relief(s) on the backside that keep the grips located. I don't think shrinkage would be a factor with original grips, unless they were processed/shaped while still slightly green...or if the gun spends its life in a climate that is generally more arid than Western Europe, it is probable that they have shrunk a bit. Depending on the geometry of the situation, it could account for the dimensions you give for the displacement. One might try to re-hydrate them slightly by leaving them in a sealed box with a slice of bread for a week or so, checking them daily to see if the fit improves. when satisfied, a round of oil finish or two would seal them and retard their tendency to dry.

I hope this helps. Let's count our lucky stars that the Germans did not use Franzite as the original material for grips!
