Recently had to remove rig at a local match - grabbed our supervising RO and told him what I needed - he followed me to the safe area and had me stow magazines away from the safe table then remove the rig and make the adjustments and then re kit back up and then reclaim mags and rejoin the match. I was satisfied with this approach but I do not know how it would have been handled if observed without an RO in attendance.
Thr primary goal is repeatable and observable safety.
