There is no single answer to this question as it depends on a number of factors, including the type of gun you are hiding, the environment in which it will be hidden, and your personal preferences. However, some general tips that may help include hiding the gun in a difficult-to-reach or hard-to-see location, using a false bottom or compartment within a piece of furniture, or wrapping the gun in something to disguise its shape. Ultimately, the best place to hide a gun is somewhere that only you know about and feel comfortable with.
