1kg trigger weight generally refers to the force required to pull the trigger of a firearm or airgun, or a physical precision calibration tool used to measure and test this exact force. Here is how a 1kg trigger weight applies to shooting and maintenance:
Competitive Shooting Regulations: In many international shooting sports (such as ISSF 25m Standard Pistol and Center fire Pistol events), a minimum trigger pull of 1kg (1000g) is legally required.
Trigger Weight Tools: To ensure your firearm complies with these rules, shooters use physical, high-precision calibrated weights (or digital gauges).
You hook the weight to the trigger and gently lift the firearm; if the trigger does not release, the pull weight is 1kg or greater, meaning it passes inspection.
