Instead of a plain and simple house key, get yourself one of these awesome gun keys! It's the perfect way to tell your keys apart and features a print of a 45 caliber handgun. Great to use as your main house key.
Smith & Wesson BODYGUARD® 38 - My personal favorite, perfect for Concealed Carry. "The first in personal protection with integrated lasers, the Smith & Wesson BODYGUARD is uniquely engineered as the most state-of-the-art, concealable and accurate personal protection possible. Lightweight, simple to use and featuring integrated laser sights – nothing protects like a BODYGUARD. Get one and carry more confidently, walk more confidently."
