Depends on what kind of combat style your comfortable with:
For long range combat choose rifle, for mid-range to up close and personal choose pistol or carbine.
Good Luck!
Carbine or pistol eh... Seems like it depends on what you're into.
Carbineers get a kd that actually works...
Pistoleers get... well... cheap guns. Ok, to be fair... Cheap, fast guns.
If you're going to master either of them, I think there's no comparison -- carbineer is more useful, at least for pvp. If you're just going to dabble, then you might think about pistols -- the techniques line (which contains all the specials that actually work except for pistol melee D 1) has some very nice defensive bonuses, that make it more useful than the carbine line that contains charge shot.
Of course, if you really want to be a doc and pvp, then go doc/cm. Combat medics can single-handedly turn the tide of any battle. Plus, there are few things as satisfying as hitting 15 or 20 people at once with an area mind poison... 
I'm a master doc, 4-3-0-4 combat medic, and 0-0-4-0 pistoleer (trickshot). If it weren't for the fact that I make my living selling stims, I'd be a 4-3-4-0 doc, mcm, and trickshot. With that, you could buff yourself adequately, heal poison and disease (and dizzy!), and still be able to throw area poison Cs and spam fanshot... Even with no accuracy bonuses, you can hit anyone who doesn't have stacked defense mods.
