Okay, let's say your only avenue of escape from a potentially escalating situation is to hop a knee-high fence (maybe out next to a 7-11) so that you can flee. Are you going to disregard that option because it violates Rule 7? I'd say no, because the gun is in a holster which (hopefully) covers the trigger guard. That means you can safely ignore Rule #7 because it isn't applicable to your current situation.
The point I'm attempting to communicate is that the rules are going to depend on the weapon in question and the circumstances in question. Rule 3 is completely and utterly necessary for a 1911. It is not necessary for a DA revolver. This is not to be construed as license to go around fiddling with a DA wheelgun while keeping one's finger on the trigger. This is an "exception" to the 1911-centric rules in the circumstances so keenly identified by The Real Hawkeye in an earlier post.
