if the gun has a sentimental value, lock it up. get another (same gun if youy like) and carry that. depending on where the problem arises and what happens you may get it back but after alot of jumping through hooops and lawyers paperwork (depends on department you are dealing with as some love to keep the guns if used for any reason). if you are going to carry it get one you dont have a sentimental attachment to (oops the gun got scratched getting out of the car, oops i must have gotten some sweat on it and it rusted a bit or whatever). i have a few i have sentimental attachments to and they come out only for range and cleaning, i have plenty of tools for defense that are worth the loss to save my life or one of my family.
