Never owed one, and most likely never will. I prefer the .45 ACP. I don’t think that the .40 is dead, but I believe that it is not as popular as it once was. This is true with a lot of newer cartridges. It will lose a little bit more popularity each year, but most likely will be available in limited numbers. Not that the .40 is new. It has been around a little while, a cartridge between the 9 M/M, and .45 ACP. Kinda like the .41 Mag. that will never be as popular as the .357 or .44 Mag., but still a good caliber.
