A close friend spent a considerable amount of time in Vietnam as a member of the 5th Special Forces and one day while telling a "war story" he mentioned, that, in addition to his long gun, that day he was also carrying a 1911, a Browning Hi-Power and a .25 acp. Knowing he was a proponent of the, "If you are going to shoot full size people you should be shooting full size bullets" mind set I had to ask him what was up with the .25? His answer was short and sweet, "Some people don't want to be shot with anything, it just might make them think twice and stop what they're doing."
