The OTs-20 Gnom (ОЦ-20 "

[12,5-мм револьвер ОЦ-20 "Гном" // журнал "Оружие", № 1, 2000. стр.49] is a Russian revolver manufactured by the
KBP Instrument Design Bureau

. It uses a proprietary 12.5x40mm STs-110 cartridge developed from a
32 gauge shotgun cartridge.
It can fire lead slug (STs-110-04), lead shot (STs-110-02), and armor-piercing steel-core slug (STs-110) cartridges, as well as three types of non-lethal ammunition.
The revolver is smooth bore and so it lacks accuracy
but has high muzzle velocity and stopping power.
A tactical laser projector is available that mounts on an accessory rail under the ejector rod shroud. It is turned on and off via a pressure switch that can be attached on the grip; the operator just squeezes the grip and the projector goes on or off.
The manufacturer claims that the steel-core slug can penetrate 4.5 mm of "standard body armor plate" at 25 m. They also claim that the dispersion of this bullet at this distance is about 5 cm.
Development
The gun was designed by A.N. Nevizhin (А.Н. Невижин), V.I. Seregin (В.И. Серёгин) and S.V. Zotov (С.В. Зотов) at
