If memory serves me correctly:

McGyver, in one episode has a flashback to an event in his childhood, in which a friend is killed by a gun McGyver or another kid was “playing” with and thus his “distain” for firearms. I believe in various episodes he does point out his dislike of firearms.

It is interesting that in SG1, RDAs use of guns and other weapons is paramount to his character and his character’s survival.
