Stechkin APS grips

The Stechkin APS (Avtomaticheskiy Pistolet Stechkina) is the iconic Soviet selective-fire machine pistol, designed by Igor Yakovlevich Stechkin (1922–2001) as a compact PDW for vehicle crews, tankers, artillerymen, and pilots—bridging the gap between pistols and obsolete submachine guns like the PPSh-41 after the AK-47 adoption

Fresh from graduating the Tula Mechanical Institute in 1948 (thesis on a 7.65mm self-loader), 26-year-old Stechkin began development at the KBP Instrument Design Bureau in mid-1948. First prototypes appeared by 1949; field trials (April–June 1949) included a grueling 20,000-round endurance test against an Astra machine pistol and PPS-43, proving promise despite flaws: excessive weight (1.9 kg with holster-stock), non-adjustable sights, short sight radius, and under-barrel recoil spring

Stechkin redesigned extensively, incorporating Makarov PM elements (silhouette, slide rails, extractor), lightening the frame, simplifying the DA/SA trigger, and reshaping the guard. After successful military trials, the APS was formally adopted on December 3, 1951, alongside the Makarov PM in 9×18mm Makarov, earning Stechkin the Stalin Prize (1952)

Production ran 1951–1958 at Vytatsky Polyany Machine-Building Plant, yielding ~30,000 units. Features: blowback operation, 20-round double-stack magazine, detachable wooden holster-stock, ~600 rpm full-auto, and reliable controllability

Though phased out by the AKS-74U in the 1980s due to cost and bulk, the APS saw use in Vietnam, Afghanistan, Chechnya, Syria, and Ukraine. The suppressed APB variant (1972–1973, ~2,000 converted) served Spetsnaz

The Stechkin APS endures as a Cold War legend—innovative Soviet engineering for elite close-quarters defense
