You might want to consider putting a pistol rug inside the ammo can gun case to keep your handgun from being banged around and scuffed up while it's in the case.
Another option is to line the inside with foam glued onto the case sides, bottom, and top.
However, the pistol rug option is quicker and probably cheaper, if you count your time for anything at all.
And there are times when you might need the rug to transport the handgun, like when you're walking into Guns Unlimited, for example.
And the dessicant bags recommended up above are essential. Unless you hold a preference for antiqued, rusty guns.
Bottom line: It'll work for you.
