Not quite, the 10mm existed prior to the FBI selecting it as their cartridge of choice. After determining the recoil was a little excessive for some of their agents they put out a request to manufacturers for something similar but with a little less "oomph." S&W developed the .40S&W cartridge that was eventually adopted but hilariously they weren't the first manufacturer to put out a gun chambered in their own new round. Glock "appropriated" some of the cartridges that S&W were showing off at a trade show, made some minor modifications to their Glock 17 to accommodate the cartridge, and submitted the new gun to the FBI before S&W. The FBI ended up choosing Glock.
