On the pulsar, the internal smartgun is Restricted. Now, are people going to look at it closely/care, probably not, but if you're going restricted, go ahead and get firing selection change: SA on it.
In my version of SR4A the Yamaha-Pulsar is already SA, I don't think you wanted to give it BF-capability, that's not very useful with 4 darts in the magazine! - Did I miss an errata there?
Update on the character: As my GM decided to give us (Cha x2)-Points free for Contacts, I now have the homeless-network as a groupcontact, as depicted in the bbc-"Sherlock"-Series! (And I got rid of my debts, as they didn't fit my concept of the character anymore, and with freed points from my contact, I balanced the money-issue)
