GP100 hammer bobbing in Revolver Forum Posted February 2 On 1/31/2021 at 9:28 AM, PatJones said: If the revolver is cocked and want to lower the hammer, you would have diminished control while doing it. None of the drop safeties would help you as you need to pull the trigger to drop hammer. Grab hammer, pull trigger so sear releases hammer, as soon as hammer is released let off the trigger. Some folks place their finger between hammer and frame and just roll the finger out after releasing the trigger. Those of us that shoot d.a. / s.a. production guns do something similar on every stage at USPSA or IDPA matches, it is a bit more dicey with those guns as you have to keep the trigger pulled so you clear the half cocked notch.
