And in my own never-humble opinion, a shadowrunner should select Automatics as a distant third. Pistols for most work, shotguns for really nasty and/or specialized stuff, sporting or sniper rifles for the long work, and only then should they be getting into the dakka-dakka. Automatics, whether that's SMGs or ARs or (god help you) machine-guns, are for war, whether that's street or straight-up merc stuff.
But again, that's my own never-humble opinion. Only once in my entire SR career did I pause and say, "I wish I had an assault rifle and the skill to use it." That was during what was basically an amphibious assault, and the enemy was out past 200m range. Otherwise, even the worst incidents needed nothing more than a well-placed pistol shot or two. (Rarely two.)
