Stats

In-game description

The 9x21mm 7U4 round (GRAU index - 7U4) with reduced bullet velocity, designed for flameless and low-noise firing. The cartridge features a cut edge on the front end of the core, formed by two flat edges, and increased weight.

Against which armor

Penetration 27 is above the resistance of class 2 armor (20) — while such armor is intact, the round penetrates it more often than not. Against class 3, penetrations are rare until the armor is worn down.

For example, the vests it can defeat: 6B2 body armor (Flora), PACA Soft Armor, PACA Soft Armor (Rivals Edition). The full table is in the armor classes guide.
