I hope they are considering .357 SIG. It is a better penetrator than 9mm, .40, or .45.
(And just think: if the military went to a .357 SIG standard, the price of ammo in that caliber would drop!)
He said hopefully... LOL, you’re a hoot. I doubt they have that foresight though. I suspect it’ll be 9mm as most (all?) of our current/potential allies use it. A better platform would nice though. The Glock or SIG DAO/DAK would be my choice but then again the military still lives back in the early 1900s where small arms are concerned. Im sure it’ll have to have a manual safety, be all metal and be hard and expensive to maintain. :(
I certainly understand youre tendency toward 357SIg. I like it myself very much with 40 S&W as a second choice then 9mm. I prefer a SIG DAK or Glock.
All those calibers won’t go thru body armor. 9mm is a common round found all over the world. They should go with Glocks.
