The only thing I don't like about anything hanging off the gun is i'm a still hunter. I try to keep all movement to a minimum. Anything swinging under the gun will be seen by the game.
The safety stays over the cap until time to shoot. I pull the trigger back, then thumb the hammer full back, release the trigger and let the hammer slowly forward to catch at full ****. No "cocking click". Then the safety comes off and, yes, at that moment it will hang a lanyard length below the gun for a few seconds before firing.
