9x18mm JSP-AP (Jacketed Soft Point - Armor Piercing), also called 9x18mm PBP, is a type of ammunition which was partially included in all three S.T.A.L.K.E.R. games.


9x18mm JSP-AP 9x18mm JSP-AP rounds use a Jacketed Soft Point; rather than expanding on impact, the bullet deforms slightly, allowing for a limited armor piercing effect.


  • The Cyrillic script on the box reads PBP, which stands for Povishennaya Broneboinaya Pulya ("Enhanced Armor-piercing Bullet").
  • The English script on the box reads JSP-AP, which stands for "Jacketed Soft-Point, Armor-Piercing".



9x18mm JSP-AP rounds appeared as an available, usable ammunition as early as Build 1844 and were usable in 9x18mm weapons up to Build 2215. Compared to 9x18mm +P+ rounds, JSP rounds are capable of traveling less distance and have a weaker stun capability, but are superior in armor piercing and impulse attributes.

Shadow of ChernobylEdit

JSP-AP rounds are partially implemented in S.T.A.L.K.E.R.: Shadow of Chernobyl. They have an in-game model and are defined in code, but lack inventory icons. If somehow obtained they cannot be used in any weapon. The ammunition's ballistic properties are the same as in previous builds of the game.

Clear SkyEdit

Similar to Shadow of Chernobyl, S.T.A.L.K.E.R.: Clear Sky provides an in-game model and code definition for the ammunition, but no icons and no support in any existing weapons. Additionally, the ammunition's ballistic properties have been modified to be identical to those of +P+ rounds.

Call of PripyatEdit

S.T.A.L.K.E.R.: Call of Pripyat fully removed JSP-AP rounds from its code, but still contains the in-game model for the ammunition.
