Following is a list of recommendations for you to follow. If you use these guidelines you reduce the chance of malfunctions. Clean and dry is the key. Do not keep it in a leather holster because leather tends to absorb and retain moisture. Zipper type gun rugs can do this as well.
Guns can rust quickly.
This includes unloading your magazines or speed loaders and inspection your ammo for oil or corrosion. Refer to proper cleaning procedures in your owners manual. Clean barrels from the chamber end whenever possible as this saves wear on the muzzle. Don't use cleaning solvent as lubricant. Instead, use a good oil specifically designed to lubricate firearms.
