If you absolutely don't like other guns, then that's understandible, but I have to agree with those that say if you want the same gun for multiple roles, why get copies? You already have several copies of the .40, do you really need another one for home/vehicle defense? (The question is need, not want).
Personally, if I were to have guns for different locations, I'd rather they be tailored to the location. If I were to have multiple copies, I'd rather just move it from point A to point B. Nightstand gun goes in the safe when you walk out - why not walk out with you? It goes in your truck when you're at work, and goes with you when you're elsewhere. That's 3 roles (CC, HD, car) that are covered by one gun. Saves some money.
