It's just policy of the place you shoot at. They dont want you messing with a loaded gun before getting to a lane to shoot.
When I shoot action pistol, I wait until it's close to my time to shoot. Unholster and put loaded gun in range bag
(finger off the trigger and maintaining safe direction). Practice with my carry gun's twin.
At then end of the evening, put twin in range bag, holster loaded carry gun.
