9x18mm +P+ is a type of ammunition featured in all three S.T.A.L.K.E.R. games.
The 9x18mm cartridge is very common and cheap and readily available from most traders. The +P+ munitions have an overpressurized cartridge alowing for higher muzzle velocity. Due to the slug's weak integrity, they are not very effective against armored targets, but they deal just under twice as much damage in these cases compared to standard 9x18mm FMJ.
