There has always been some question on whether or not to store a gun in a sock or a carrying case. I have heard of some people having a shotgun in a sock for only a week or so and it rusted. I have always been leery about storing a gun in a sock for any length of time, although a lot of people do it. You never can tell what kind of chemicals are in that sock. I am not trying to run anyone down or anything, but I always check my guns- pretty much weekly, or after a couple weeks, to see that they are doing all right. To leave a gun in a safe for any length of time without checking it would really scare me. I can show you two of my handguns that have rusted after only two or three weeks in my gun safe because I did not check it. But good luck trying to repair your gun.
