I used to have a concealed carry permit and carried a Astra A-80 .45 with me everywhere I went when I was off-post. Of course, I was in the military at the time in a position that required Top Secret, so there was actually some (sort of) need or justification.
I used to own several firearms and my wife (a former Marine) had a handgun. When we decided to have kids, we sold all our guns. We have an agreement now that we will not have any guns in the house unless we have a gun safe to store them.
That having been said, I am probably going to get a Glock .45 (whichever model fits best in concealed carry) soon once our gun safe is installed.
