The *hoax* was the narrative that the FBI, post Orlando, needed an "upgrade" in pistol caliber. That was really only needed as a diversion from the sorry fact of bad training, among other things.
While I believe that this is true, the 115 grain cup and core bullets the police were carrying back then were not as good as the bonded and heavier bullets on the market today. Those were the result of a lot of R&D. The .40 S&W offered better performance with the bullets of the era in which it was invented and became popular.
"Post Orlando"? What happened in Orlando and when was it?
