And in a modest attempt to get back to the original question, THIS gun nut would recommend against carrying a .38 Colt or S&W for a couple of important reasons. The first important reason is cost and availablity of ammo. If you don't have a reasonable supply, you won't practice with your carry piece. If you don't practice, practice, practice, there is a greater chance that the fear-stoked nervous system will have you shooting wildly. And this leads to the second more important reason for not carrying a .38 S&W: if you don't get a good hit, you will end up pi$$ing-off the BG without doing sufficient harm to make him stop. It's just not enough gun.
Keep the heritage piece in the gun safe. Take it out and polish it and clean it and show it to your friends while you tell them the story about the cop up north and the gun coming into your possession down in Florida. But, get a weapon that you can use regularly at the range, and one that will do what it needs to do if (heaven forefend) you ever need to defend your life or the life of someone you love.
I have a little .38 S&W Iver Johnson sitting in my gun safe. It belonged to my late and beloved Father-in-Law and I am lothe to part with it. But, I carry a Glock 27 in .40 S&W because it will do the job if I ever need it.
Thoughtfully submitted,
