The CCS-12 is a pre-measured charge of irregular ceramic composite fragments designed for the PSP-2 'Gravel' scatter pistol, packaged in 8-round speed strips for rapid reload. Each load consists of approximately 12 grams of ceramic-metallic composite pellets of deliberately irregular shape and size, propelled by a 45mL compressed CO2 canister. The irregularity is intentional — uniform shot produces predictable wound channels, while the CCS-12's random geometry creates chaotic, unpredictable tissue damage that is difficult to treat surgically.

The ceramic composite material is specifically chosen for its scanner invisibility. The pellets contain no ferromagnetic components and emit no RF signature, making the loaded weapon effectively invisible to standard security scanning systems. This is the PSP-2's primary selling point and the reason the CCS-12 exists as a distinct ammunition type rather than simply using conventional shot. The ceramic also fragments aggressively on bone impact, producing secondary projectile paths that extend the wound channel beyond the initial penetration depth.

The CO2 propulsion system gives the weapon a distinctive acoustic signature — a sharp hiss rather than a bang — and limits effective range to close quarters. The CCS-12 is designed for engagements measured in meters, not tens of meters, and the scatter pattern beyond 4 meters reduces individual pellet energy below reliable incapacitation thresholds. Within its intended range, however, the combination of multiple irregular fragments, ceramic fragmentation on bone contact, and piezoelectric discharge from the weapon's barrel assembly makes the CCS-12 one of the most devastating close-range antipersonnel loads available.
