9×42 Quiet is a caseless ammunition developed by Rokheus & Surma Equipment and Logistics Support for their Rokheus & Surma R36 Special Purpose Carbine, intended to defeat body armor and cause greater terminal effects on soft tissue when fired from a suppressed rifle.

Using 300 grain armor piercing 9mm projectiles with a Nerimium ballistic tip, heavy projectiles have large enough sectional density to pierce common body armor despite flying at subsonic speeds. Air pocket within the armor piercing cap causes the projectile to yaw or “tumble” within soft tissue, creating a larger wound channel.
