Best post yet.
For a civilian, pulling a gun on someone is normally an unlawful act; it is, of course, permissible under certain circumstances. Whether a particular circumstance meets the thresholds of justifiability depends on the particulars, but whether it will be
judged to have met said threshold will depend upon evidence and testimony, some of which may be contradictory, or perhaps impossible to gather after the fact.
Unless it is crystal clear that the assumption of justification was incontrovertible, it is best to not air the details in a public forum for later scrutiny. There is not only risk related to the incident at hand (unless the statute of limitations has expired), but there are also potential risks regarding indications of state of mind should a poster become involved in an ambiguous situation in the future.
It has been said here many times before, but the best thing to do after producing a weapon is to report the incident to law enforcement immediately. Otherwise, should the other party report the incident first, they will likely have the upper hand in terms of credibility.
