The 9×39 is based on the Soviet 7.62×39mm case but with the neck expanded to fit a 9.27 mm bullet. The intent was to create a stealthy cartridge for the "Vintorez" and "Val" projects which required more power, range, and penetration than 7.62×39 US or 7,62×28 rounds tested at the time. The round is originally designed to have an optimistic effective lethal range of 300 to 400 meters and a maximum penetration of up to 10 mm of steel at 100 m. Like the 5.45×39mm cartridge, the 9×39mm SP-5 features an air pocket in the tip, which increases its tendency to yaw or "keyhole" upon impact, thus increasing soft tissue damage in human targets. The armor-piercing SP-6 cartridge is more effective against light armor, vehicles, or light barrier targets. Commercial Wolf and Tula brand Ammunition that was being imported into the United States was subsequently banned on September 7, 2021 by then president Joe Biden as part of sanctions against Russia for poisoning of Alexei Navalny. Since many users in the U.S. had adopted the 9×39 round prior to the import ban, they are now forced to reload their own ammunition. However, multiple companies worldwide produce.365" and.366" bullets suitable for reloading 9×39 cases, including Hornady, Barnes, Nosler, Prvi Partizan, Lapua, and others. Roswell Manufacturing has developed what they are calling the 9x39US, which has slightly different specifications from the original 9×39 according to C.I.P. standards.

V. Zabelin, L. S. Dvoryaninova. It consists of conventional FMJ bullet with a mild steel and lead core. The primary goal of this version was to achieve accuracy. SP-5UZ – The SP-5UZ (СП5-УЗ) is an SP-5 variant with an increased charge intended for a factory-specific strength testing of the weapons. SP-6 (7N9) – The SP-6 (СП-6) was developed by Y. Z. Frolov and E. S. Kornilovova. It has a hardened steel armor-piercing core, designed to defeat body armor, which was being issued in the 1980s (such as PASGT). It can penetrate 2 mm of steel at 500 meters or 6 mm of steel, 2.8 mm of titanium or 30 layers of Kevlar at 200 meters. At 100 meters it can penetrate 8 mm of steel or GOST 3 rated body armor, while retaining enough power to inflict damage to a soft target behind it. SP-6UCh – The SP-6Uch (СП-6Уч) is an SP-6 variant intended for training. PAB-9 (7N12) – The SP-6's bullet is expensive to manufacture, so an attempt was made to make a lower-cost version of the cartridge. The PAB-9 (ПАБ-9) used a stamped rather than machined steel core. It was not accepted due to higher wear it caused to barrels. As of 2011, its usage by Russian troops is prohibited. SPP – The SPP (СПП) (SPP: Snaiperskiy, Povishennaya Probivaemost; "sniper – increased penetration") is a sniper round with increased penetration. BP – The BP (БП) (BP: Broneboinaya Pulya; "armor-piercing bullet") is an armor-piercing round. Three modernizations of PAB-9 were created under the designation of BP to remedy its unusable performance. There is at least one civilian load of this cartridge based on the SP-6 design. It is used by civilian 9×39mm firearms such as the (touted) civilian variant of RSh-9, MTs-570.
