FWIW & IMHO:
Keeping your gun in that gunwrap, foam rubber, and box will probably do more damage that good. Buying a good, high quality gun rug, cloth or leather exterior, chamois or soft flannel lined, & gun wrapped in a nice, clean portion of an old t-shirt, probably now days in a microfiber towel, & stored in a nice warm but not humid place like an indoor safe. Never put the gun away without wiping it down very good, especially if someone has been handling it. Some people have a very acidic fingerprint and definitley do not let them handle the gun. Light coat of oil on the non-blued parts, such as the barrel inside, & sometimes some of the action work, springs, & hammer faces, & so forth. Next trip to the gunstore, purchase some of those active dehumidifier bags and keep them in the proximity of where the gun is kept. Might want to look up a good website for handguns such as pistolsmith.com for further info. HTH
