In my opinion, older, collectable firearms should be saved for shooting and enjoying once in a while and not be subjected to the rigors of being a defensive firearm.
Use a new, current manufactured firearm for self defense.
But, what ever floats your boat.
Of course, some handguns that I purchased in my youth, I do not feel they are "old". In reality, some of them are pushing 40 years old and should be afforded the retirement that they have earned.
(Side bar: I have a few Garands that are younger than I am. Geez, I'm getting old.
