afaik what Pegasus says is as official as you get.
Which means: Not at all.
The only thing that's official are errata, and we don't get those (at this point in the production pipeline, understandably).
What Pegasus' SR team says is just as much interpretation in terms of conflicting RAW as it is if a freelancer says it, if I say it, or just about everyone else in this or any other forum.
The fact of the matter is that most people, including the writers don't even go into that much thought about loopholes. Sure, Bloodzillas eventually get mentioned and fixed, but something as inconsequential as "How do I handle an obscure fringe case with guns that basically never occurs" won't ever be addressed, because common sense dictates: "Do it as your GM wills, after discussing it. If your interpretation isn't shared by the majority of your group, your interpretation is wrong for your group."
A question such as this won't make it into the errata, and not even an FAQ, simply because the question isn't asked frequently.
The funny thing is, this kind of service (an official rules crack team) isn't even needed. Most people I know don't even read the errata or are aware of different printings of the rulebooks.
Games Workshop offers (or offered, I don't know the current state of affairs) this kind of thing. You can even call a hotline and some dude will answer your question right then and there. The funny part: Try it. Then call again, see if you can get another dude on the line.
We tried it, we got three different answers from three different guys. All of the answers were official.
