We have an attached 2 car garage with a 8x10 enclosed "pantry" area. I'm thinking of putting a gun safe in the pantry room. The garage is not heated and if I had to guess the temperature swings throughout the year range from low 40's in winter to upper 80's in summer. The temps are mitigated somewhat by the walled off pantry and the fact that one wall is formed by an inside wall (living room). Anyone see a problem with this plan? Anybody do something similar? The security part is not my concern, it's the fluctuation in temperatures and humidity that have me second guessing.
