"Cartridge, 9mm, Ball, M882
The M882 cartridge is approved for service use with the M9, M10, and M11 pistols, both for training and for combat. The ammunition complies with NATO STANAG 4090 test requirements.
The M882 ball cartridge consists of a brass case, a copper alloy jacketed lead core bullet, a two-piece boxer-type primer, and a double-base propellant. M882 NATO ammunition manufactured under U.S. Government contracts by Winchester-Western (Olin Corp.) and Federal has a 112 grain FMJ bullet and provides 385 meters/sec. (1263 fps) muzzle velocity as determined by official military test standards measured at 15 feet from the muzzle. The cartridge weighs 179 gr. in total and is 1.165 inches (29.591 mm) in length. M882 NATO 9mm ammunition carries a headstamp with the maker and year of production--example: WCC 88 stamped on a lot made in 1988 by Western Cartridge Company (Olin's Winchester-Western ammunition division) or FC 86, a 1986 lot by Federal Cartridge. The ammunition also carries the NATO stamp of a circle around a plus sign. M882 has been made with and without a cannelure (groove) around the midsection of the brass case.
A second cartridge has been procured, called "9mm Ball". It is about 0.1mm longer than the M882, but is not authorized for use in service pistols."
