There are several ways to interpret that, and the only correct way would be known by the writers. To me, that simply allows a pistol wielder to also go John Woo upon some unfortunate xenos. Nothing in that section specifically prevents you from doing so with Baisc weapons.
The standard position seems to be that it isn't explicitly forbidden.
Repeat after me. "Just because the rules don't say you can't, doesn't mean you can."
The rules for Called shots gives examples of types of locations you can pick, but since it doesn't limit it to only those locations then obviously I can target a called shot on his cerebellum, meaning logically I'll kill or permanently paralyze him with any shot that deals damage. I could also do called shots on his sense of self worth, ability to see the color green, and inability to summon delicious hot muffins from thin air. Man, called shots are awesome.
RAW the answer is that yes you can dual wield basic weapons, but you may not use the semi-auto and full auto actions with two basic weapons or two heavy weapons as the inclusive language used in the description of these actions only mentions pistol weapons, excluding the use of other types of weaponry. All other actions possible with basic weapons use no language which would exclude their use.
Only talents or abilities (like the micro weapon upgrade) that would cause the basic weapon to be treated as a pistol weapon would allow them to be used with the full-auto or semi-auto actions.
RAI... *Shrug* Dunno.
