[John Sabato]

Since you live in georgia where the humidity is high, I would leave them unwrapped, and rack them on surfaces that will not tend to be moisture traps...and make a habit of checking their condition on a frequent basis... The shelves of my gunsafe are lined with linoleum or just bare painted metal for just those reasons..

Use of a ziplock may block water droplets from getting on your Luger, but it will also be a source of condensation forming inside the bag from the air you trap in there when you zip it shut. Another issue in my mind would be the concentration of any excess lubricants on the original wood grips... There are those who use food wrappers that suck out all the air like a vacuum before sealing... I have my doubts about those as well cause what will happen if the plastic gets punctured? Won't the vacuum suck in whatever atmosphere exists outside the bag and bring it right in there with your prize Luger?

Cotton rags would also have a tendency to wick moisture out of the air and place it in close proximity to the metal surfaces.
