Speer Gold Dot 124gr 9mm+P in SIG P226 magazines. Overpressure ammunition, commonly designated as +P or +P+ (pronounced Plus-P or Plus-P-Plus), is small arms ammunition that has been loaded to produce a higher internal pressure when fired than is standard for ammunition of its caliber (see internal ballistics), but less than the pressures generated by a proof round.
Each of the 9mm P.A. cartridge variants are distinguished by a proper color: green, yellow, blue, red, etc. 9mm P.A. ammunitions can be used for different purposes depending on the legislation, these include military training, cinema props, self-defense (rubber bullets can only be used in certain Eastern European countries), dog training, historical re-enactment, holiday or new year ...
