(A collection of gun-related items, running more or less weekly, that proves The End is near.)
During the Spanish-American War (1898), the U.S. Army learned—the hard way that the .38-caliber revolvers it was issuing were not up to the job, and eventually scrapped them in favor of the Model 1911 automatic in .45 ACP, which gave exemplary service until the mid-1980s, when it was phased out.
The new pistol was the Beretta M82, in 9mm, which is the same caliber (.357) as the .38 Special. And, like the .38 Special, it does not pack the punch to do the job. So the U.S. Special Operations Command and the U.S. Army were tasked (as milspeak would say it) to find a replacement for gun and cartridge, but they cannot agree on what’s required, and so the project is tabled, insuring that for the near future at least, soldiers and Marines will go into combat with a handgun that is generally considered inadequate for the job.
