Pistol Specializations, I can't seem to figure this out Options

[Typhon]

So when it comes to pistols I'm normally pretty generic, either a Pred or Manhunter is fine by me. So I'm making a new character and a buddy of mine lends me Arsenal (great book btw) and I decide to check out some of the pistols in there and I realize I'm not sure what specializations will work with what guns.

So here is my problem, SR4 Specializations for pistols are Hold out, Taser, Semi-Automatic, and Revolvers. Tasers being their own specialization is fine by me, but what if a hold out pistol is also a revolver or a semi-auto? It seems like if you are going to have a class of weapons (Hold outs) be a specialization, you should also be able to specialize in other classes like the light pistol or the heavy pistol. What is the the Deputy? It's a revolver but it fires in semi-automatic mode. If I had to choose I'd say it would use the revolver specialization because its class is a 'revolver' but then what makes a gun a semi-auto? The Cavalier scout is a hold-out that in the text is listed as a semi-automatic pistol.


What specialization does the Ruger Thunderbolt use?


Do the specializations overlap? Would I be able to use my specialization in revolvers to fire off anything with (cy) in the ammo column even if it is a hold out or fires in semi-automatic mode?

I guess I can't seem to wrap my head around having being able to be specialized in a class of weapons or a particular firing mode. Perhaps it is just bad word choice on the part of the writers but it almost seems like the specializations would make more sense as : taser, hold-outs, light pistols, and heavy pistols. but then you'd just be setting up the specializations to read : "crap", "crap", "mega-crap", and "correct choice" (IMG:style_emoticons/default/nyahnyah.gif)

Can anyone illuminate me here? Am I totally off?
