Preventing unneccessary loss of life is more important than indoor decoration. You can always put the safe in your closet where no guests will see it.
IF you do not use a gun safe. Read this.
ALwAYS have a trigger guard in addition to barrel or breach into action locking mechanism.
ALWAYS Keep your ammunition locked seperatley and away from your weapon/firearm.
NEVER Get a plastic based trigger guard. NEVER let anyone else see or touch your lock keys. They can be copied for 5 dollars at a walmart.
If its your home defense fire-arm, take into account: Will it be more useful loaded and ready to go to defend from violent deadly intrusion, or will that more likely get my child killed from an accident.
Keep all ready to use for defense in home firearms, for me, i choose breach locked through the magazines or barrel. and i leave off the trigger guard. The breach locks will make it impossible to chamber and fire a round even if you pull the trigger. I keep the key on me at all times.
Above all else, simply not keeping track of your keys can result in theft, injury, or worse.
