<h2>Synonyms</h2><p>9 × 38 mm</p><h2>Armament</h2><p>A-91 and MA minature assault rifles; AS silent assault rifle; VSS silent sniper rifle (BSK silent sniper system); OTs-14 assault rifle.</p><h2>Development</h2><p>The 9 × 39 mm cartridge was derived from the 7.62 × 39 mm cartridge by expanding the case mouth to accept the large 9 mm bullet. The cartridge was developed for use in assault rifles and in silenced weapons that must fire subsonic bullets in order to fully take advantage of the suppressor's characteristics. The 9 × 39 mm achieves this by firing a relatively heavy 16.2 g bullet at approximately 290 m/s. There were two versions of the cartridge developed, the SP-5 Ball and the SP-6 armour-piercing variant.</p><h2>Description</h2><p>Aside from the size of the bullet, the 9 × 39 mm cartridge is a conventional tapered, bottlenecked rimless design, Berdan primed. The case is of lacquered steel. The SP-5 Ball bullet is a boat tail bullet with a two-part lead and steel core, similar to that of late production 7.62 × 39 mm cartridges. The lead core extends from the base of the bullet about halfway up its length, where a steel penetrator forms the rest of the core. The steel core has a flat tip, leaving a small airspace in the nose of the bullet, which aids in terminal ballistics against personnel targets. The SP-6 armour-piercing bullet incorporates a steel penetrator which extends the entire length of the bullet and protrudes from the tip of the gilding metal jacket. The SP-6 can further be identified by its black tip. The steel penetrator is surrounded by a lead sleeve for about two-thirds of its length inside the bullet jacket. This may serve to reduce bore erosion by providing a degree of jacket compression as the bullet is fired and engages with the rifling in the weapon's barrel.</p><p>RUSSIAN FEDERATION</p><h2>Manufacturer</h2><p>Tula Ammunition Factory</p><p>Type: Subsonic Ball: FMJ; 16.2 g; MV 290 m/s</p><p>Type: Subsonic AP: Composite; 16.2 g; MV 290 m/s</p>
