Sorry, but that’s just not true.
The FBI never considered the full power, 200gr/1300fps loading in 10mm—and it was never issued for training or street use. The wanted a round that duplicated the 185gr .45 (considered one of the best rounds on the street at the time)...hence the “FBI Load”—180gr@950fps. The .40 loading they switched to had identical performance to their 10mm loading (And, considering that the pistols they switched to were lighter than the all-steel 1076’s, would have MORE recoil, not less).
Quotes from someone who was there:
This testing resulting in the FBI’s adoption of the 10mm round, downloaded to about 950 fps, using a Sierra 180-grain jacketed hollowpoint. The long round, however, required a very large frame pistol. Adopted was the Smith & Wesson Model 1076.
And:
The Bureau would later issue Glocks in .40 S&W caliber, with basically the same ballistics as the FBI handloaded 10mm.

10mm Handguns and the FBI
The FBI’s brief dalliance with 10mm handguns led to the development of the .40 Smith & Wesson cartridge, and experts are still divided on the question of the 10mm’s application for law enforcement.gundigest.com
I’m with you on them not going with the full power load. I’m well aware of that. I remember the term “FBI load” I always shot issues Glocks not the Smiths. I have shot the Smiths and I really like them, but that’s why I have and shoot Glock. The S&W 1076 and 1006 which had issues was also a reason for the swap for the .40S&W.
