I dont know if this has been said, but lets not forget about Etain Tur-Mukain, she used an LJ-50 concussion rifle quite often, and preferred it almost to her lightsaber. (did i spell that right) from Republic Commando (also good books). Obi wan used a blaster not in a dire situation as aforementioned, but in the Cestus Deception book, he carried it as standard equipment. Also, didn't Mara Jade use one? of course she was part of the new order, which because it was mainly founded by Luke Skywalker, he didn't know rules such as no marriage. In Republic Commando (true colors i think), it gives an interesting view on the force, saying that the jedi of the republic had strayed from their original goal, which was not to sustain a corrupted government, but to do good and help those in need, regardless of regulation.
