Semper Fi brother, good question. When I'm in the field which has ran as much at 250 days out of one year, guiding, hunting,setting up and filming outdoor/hunting TV shows, etc. situations dictate my primary piece, since these events could be focused around rifle, pistol, blackpowder, bow, crossbow, cameras, but my back up is the same I carry everyday, a 3" SW low profile 5 shot, model 60, stainless with handle grips. This guns doesn't incumber me due to weight or size, It is so comfortable I don't feel it, it is also lighting quick to get at, with with the 3" barrel with hi lighted sights, makes quick target aquisition easy, accuracy 4" groups off hand at 30 yds. and the knockdown of a .357 or the comfort of a carefully selected .38. Either bullet, this gun is effortless to pack, conceal ( it is my CHL pistol) and accurate enough to harvest small game with. Stainless still makes everyday cleaning not so important as with blued models as well.
