OTs-20 GNOM revolver 12.5mm
The 12.5 mm OTs-20 GNOM (Gnome) revolver is another short-range pistol designed for use by internal security and paramilitary units. It fires a series of three special 12.5 × 40 mm cartridges based on brass-cased 32-gauge shotgun cartridges. These include the STs110 armour-piercing cartridge with a steel projectile, the STs110-04 containing a high stopping power solid lead projectile, and the STs110-02 lead shot cartridge.
The sturdy, steel-framed OTs-20 GNOM is a conventional single- or double-action revolver with the cylinder containing five rounds. For reloading, the cylinder swings out to the left. A laser target indicator is available as an option.
The armour-piercing projectile fired from the STs110 cartridge can penetrate 4.5 mm of armour plate at a range of 25 m.
