lên cò

Hắn từ từ lên cò khẩu súng lục.

Definition

1. Verb phrase:
   • To cock a gun: The primary meaning of "lên cò" is the action of pulling back the hammer of a firearm (such as a pistol or revolver) to prepare it to be fired with a trigger pull.
   • To prepare to fire: It describes the specific step in operating a gun where the mechanism is set, making the weapon ready to discharge.

Usage Examples

• Verb phrase:
  • Hắn từ từ lên cò khẩu súng lục. (He slowly cocked the pistol.)
  • Trước khi bắn, nhớ lên cò. (Before firing, remember to cock the gun.)
  • Cảnh sát ra lệnh: "Lên cò!". (The police commanded: "Cock your weapons!".)

Advanced Usage

• The phrase is used almost exclusively in the context of firearms. It is a technical term for a specific manual action on older or certain types of guns. For modern semi-automatic pistols that may not have an external hammer, the concept might be described differently (e.g., "lên đạn" - to chamber a round), though "lên cò" could still be used colloquially to mean making the weapon ready to fire.
