Changes

In the late 1980s, the FBI adopted the 10mm round in the S&W 1076 pistol.  This chambering was selected due to the Bureau's dissatisfaction with the performance of the .38 Special cartridge in the S&W revolver during the infamous 1986 Miami FBI shootout, in which special agents [[Gerald Dove]] and [[Benjamin Grogan]] were martyred by two criminals.

The FBI initially chose the 10mm Auto standard as being the most powerful then available for high-capacity semi-automatic handguns, with ammunition capable of exceeding 800 ft·lbf energy (doubling that of common 9mm rounds and handily exceeding the venerable .45 ACP). Shortly thereafter, the Bureau reversed its decision, switching instead to the .40 S&W cartridge, a round of the same 10mm diameter, but a shorter cartridge length (and less stopping power as a result of correspondingly reduced space for propellent in the cartridge).

Shortly thereafter, the Bureau reversed its decision, switching instead to the .40 S&W cartridge, a round of the same 10mm diameter, but a shorter cartridge length (and less stopping power as a result of correspondingly reduced space for propellent in the cartridge).

The decision to change to the .40 S&W was caused by the inability of many FBI agents to cope with the recoil produced by a full-power combat cartridge. The length of the 10mm Auto cartridge necessitated a large frame handgun to accommodate the larger magazines and handle the stresses produced by the stronger round, meaning it was ill-suited to persons with small hands. At this point in the FBI's history, [[affirmative action]] programs had led to the hiring of a substantially different demographic than had been hired in the past. Further, many new recruits in the 1980s had generally been too young to have served in the [[Vietnam War]], which combined with a general urbanization of the United States as well as politico-cultural pressures against legal firearms ownership, left the FBI with a pool of candidates unfamiliar with and uncomfortable with firearms.  Accordingly, a change was made to a less-powerful cartridge that could be easily handled by the average recruit.

Those competing in tactical shooting competitions (IDPA, IPSC) sometimes use the S&W 610 10mm revolver, since the 10mm cartridges can be united by a single "moon-clip", giving the shooter a reloading speed advantage over the traditional revolver.
