is there such thing as a 9mm/18 or something like that my buffy was looking for a box of bullets and cant find it anywhere i dunno what it is a smaller 9mm i guess

Are you talking about a 9x19? Glocks put 9x19 on the side of there pistols for some reason. Its just a regular 9mm if it what im thinking bout.

It sounds to me that you are talking about 9x18 round that is usually chambered in russian makarov semiautomatic pistol. Thus called 9x18 makarov.

Stalkingbear is right... 9x18 is what a Russian service pistol is chambered in. If you buy loaded ammo expect the price to be above that of 9mm luger
