Storing is a different scenario to regular shooting. If storing in a humid/wet environment, I suggest oil all surfaces (lightly) and place in a freezer ZipLock bag with all air squeezed out. Make sure the oiling gets into all the nooks and crannies. I like to use Ballistol in such matters as it will emulsify all moisture present during the packing preparation. When taken out your firearm before shooting, remove excess oil and clean-dry the bore of the barrel. (NOTE: I live in the highly humid South Louisiana!)
