Why was the .40 chosen over the 10mm round?
Two-fold:
1) The FBI was having serious durability & reliability issues with the S&W 1076
and
2) Smaller-statured agents (including women, who the FBI was hiring at an ever-increasing rate in the early 1990s) were having a hard time qualifying with a large-frame pistol shooting full-power 10mm loads.
