- jmnicolas 10y agoI'd say .40 S&W is mostly a slower 10mm and is much less interesting than 10mm.
- scurvy 10y agoAll but the hottest 10mm loads have the same ballistic characteristics as 40SW these days. Sure, the Army could specify a hot load for the pistol but that's unlikely considering past choices. The hot 10mm rounds are usually reserved for subs like the MP5/10 or special units. Grunts would get regular loads similar in every manner to a 40cal.
- gingerbread-man 10y agoThey're both American-- the FBI created the 10mm because they wanted more "stopping power" after the Miami shootout. When they realized the recoil made it un-shootable and the grip was too large for half of their agents, they cut it down by a bit and the .40 S&W was born.
- MrMember 10y agoNot 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.
