8.4.1.6.2 Measuring the Weight of the Trigger Pull
The weight of the trigger pull must be measured, with the test weight suspended near the middle of the trigger (see illustrations) and the barrel held vertically. The weight must be placed on a horizontal
surface and lifted clear of the surface. The tests must be conducted by Equipment Control officials. The minimum weight of the trigger pull must be maintained throughout the competition. A maximum of
three (3) attempts to lift the weight is allowed. If it does not pass it may only be resubmitted after adjustment.
When testing air or gas actuated pistols, the propellant charge should be activated.
8.4.1.6.3 The appropriate trigger test weight that may be used for random checks will also be made available to the shooters on the range before and during the competition, and before the Finals, to allow
them to check that the weight of the trigger pull has not changed so as to contravene the Rules.
8.4.1.6.4 Random Trigger Weight control checks must be conducted immediately after the last series in all qualification rounds of 10 m and 25 m events. At least one shooter should be selected from
each Range Section (or eight firing positions for Air Pistol) by drawing of numbered lots by the Range Jury. Equipment Control Officers must then conduct the tests before pistols are returned to their cases. A maximum of three (3) attempts to lift the weight is allowed. Any shooter whose pistol fails this test or when a shooter is selected fails to undertake the test, he must be disqualified.
