Which units carry these? I promise I'm not trying to prove you wrong as I believe it, I'm just curious as to who it is?
I'm not seeking a fight. I'm just stating what I know. The list of users for each pistol is longer than I am showing here, but I only gave users for whom at least the branch of service that uses each handgun. I am not including nations that issue these handguns unless the group that uses it is identified. The M1911 was not listed for Marine Force Recon because MFR uses MEU(SOC) Pistol, which is a derivative of the M1911, but is not the same weapon.
