The current U.S. Miliatry issue 9mm ammunition is M882 which consists of a 112gr FMJ bullet at a muzzle velocity of 1263fps.

I don't believe this to be accurate. M882 ammo simply has to comply with STANAG 4090 (Nato Standardization Agreement) which allows for a range of bullet weights and energies (and pressures). It does not cover velocities per se but specifying velocity and mass would cover the energy requirement.

Quote:
The mass of all bullets shall be within the limits 7.0g (108 grains) to 8.3g (128 grains) inclusive. The energy at the muzzle when fired from the standard proof barrel should not be less than 542J (400 Ftlbf) and not more than 814J ( 600 ftlbf).

I have done some quick Googling and cannot find any evidence that a 112 gr. bullet has been issued to U.S. Military; rather the "standard" seems to be 124 gr. I have not served in the military. Perhaps someone with real military experience and knowledge can shed some light on this.
According to the Army Ammunition Data Sheets for Small Caliber Ammunition, the M885 9mm cartridge is a 112gr bullet at 1263fps +/- 5fps measured 15 feet from the muzzle (page 12-5)
