Before answering the next question, please consider that a Security Cabinet or Safe can be a lifetime investment, consider how your gun collection may grow over time. Additionally, if you plan on securing ammo and other valuables, the rule of thumb is to select a cabinet or safe that would accommodate double your anticipated long gun count. For example, if you foresee securing 10 long guns and want to use large portion of the cabinet or safe to store ammo and valuables, we would suggest at least a 20 gun cabinet or safe.
