I remember Weihrauch advising owners of their air rifles that the foam in some gun cases might react with the bluing on the gun and spoil its appearance.

Since the HW45 and 75 have alloy frames, I wondered if this warning also applies to them.

Do any of you store your HW45 in a foam lined container. When I lived abroad I used to keep handguns in foam lined cases but with the lid slightly open so that they could breathe.
