The PPS (Russian: ППС – "Пистолет-пулемёт Судаева" or "Pistolet-pulemyot Sudayeva", in English: "Sudayev's submachine-gun") is a family of Soviet submachine guns chambered in 7.62×25mm Tokarev, developed by Alexei Sudayev as a low-cost personal defense weapon for reconnaissance units, vehicle crews and support service personnel.

Finnish arms designed Amio Lahti saw the potential of a lightweight SMG concept and started his own development based on shortened 6.5×55 SE cases.

It includes Submachine guns (SMG), Machine pistols (MP), Personal defense weapon systems (PDW), and "compact submachine gun-like weapons" not easily categorized. Weapons may fit in more than one category.

Between 1922 and 1940, Aimo Johannes Lahti designed some of Finland’s best small arms including pistols, submachine guns, machine guns and anti-tank guns.

The Lahti m/AL-43 was a prototype submachine gun of Finnish origin designed by Aimo Lahti in 1943. It was chambered in the 9x35mm Lahti and later 7.62x35mm Lahti round which were ballistically comparable to the performace of the StG 44.

The initial AL-43 was developed for the 9×35 Lahti cartridge, but in 1944 Lahti developed the 7.62 x 35 cartridge and some of the existing AL-43’s were converted to the 7.62mm design. The Allied Control Commission and the end of the war effectively ended this project.

In 1943, Aimo Lahti developed the AL-43, a variant of the Suomi SMG but intended as a light machine gun chambered in a more powerful 9x35mm round (later in 7.62x35mm) which made it ballistically comparable to the StG-44. It came with a bipod and was a large heavy weapon for a submachine gun.

These included easy to mass-produce submachine gun M/44, assault-rifle like AL-43 and 7.62-mm version of MG 42 general purpose machinegun redesigned to use Finnish Army.
