I might agree with them about the .45 GAP; not sure about the rest of them.
I'd go with that analysis. I might add the .25 ACP is endangered to a degree.
.32 ACP - besides the Seecamps that are still around, there are many imported Beretta Model 81s. That alone will keep the .32 ACP in business.
.41 Magnum - secretly popular with many revolver aficionados. The ammunition might become hard to find but I don't see it going away.
.25 ACP - mouseguns in this caliber were once very popular, and might still be more popular than Seecamps. Even if everyone stops making these mouseguns there are so many out there that the ammunition will remain around. At least for now, but I do see endangerment.
.32 H&R Magnum - I don't know, maybe I should put this on the endangered list, too. Still, these guns are around.
.40 S&W - not even an argument. So many guns around in that caliber, so many people like them.
.45 GAP - did anyone ever like this cartridge except Gaston Glock?
