Question for the RO's out there: You have a new competitor with a new gun and new holster. The competitor has issues with the firearm retaining the magazine, typically falling out on draw, which he rectifies by reloading from his belt. You and the competitor determine that the holster in use is engaging the magazine release either on holstering or if they holster then ensure the magazine is seated, engages on their draw. They don't sweep themselves, but the change in holster/draw causes them to come closer to doing so several times.
No rule is violated. The firearm itself isn't unsafe. It's simply poorly fitted equipment, and the only impediment is to the competitor's time.
The rules allow for physically injured/disabled shooters to use a different start position with the imposition of a special penalty, but this isn't disability-related - purely equipment.
Aside from talking to the competitor (who's now well aware of the issue and intends to fix it before the next match), what do you do?
We opted to ensure the competitor knew of the issue, reminded him of the sweeping rules and penalty, and ensured he wasn't going to try to overcompensate for the problem by going faster than he safely could... but it felt awkward.
