The .40 Super drove a 135 grain bullet to 1,800 feet per second while generating less chamber pressure than the Winchester 9 X 23. With a 200 grain bullet the .40 Super delivers more foot/pounds of energy at 100 yards than the .45 ACP does at the muzzle. From a sheer power standpoint, the .40 Super rivals the energy generated by the .44 Magnum.
.Handguns converted to .40 Super include the S&W 4506, Glock 21, Glock 30, SIG P220, FNH FNP-45, HK USP and the 1911 Government Model (and it’s variants). Handguns set up for the .45 Super cartridge only need a barrel swap. Handguns chambered for the .400 Cor-Bon can have their barrels rechambered to .40 Super at minimal cost.
