One thing to keep in mind about atunement (which gives a bonus equal to half the initiate's grade, rounded up), is that the adept "may not recieve benefits from more than one attuned item in a single action". And since the benefit only applies specifically to using the attuned item, I would say it is an obvious exception to the usual rule of modifiers being applied to both guns after the dice pool split.
I was actually going to point the Attunement thing out in the original thread, when I was doing the math on splitting to 15 in each hand... I think the player probably missed that, or assumed it meant "per test" instead of "per action."
Also, I recently re-read Adept Centering while looking at this. While the rules say it's a "variation of Centering available only to Adepts and Mystic Adepts", it doesn't explicitly require the Free Action as Centering does. As a GM, I would rule that since it's a variant of Centering, and Centering takes a Free Action, so would Adept Centering... but I could see people lawyering up on that.
Someone brought up Tracer Ammo. I would note that the Tracer bonus only applies at ranges greater that Short (where range penalties would be in effect (yes, the range penalties could be negated by Adept Centering, as well.) Also, if you're using a Simple Action, you're limited to short bursts, so... +1.
Anyway, here's how I do 15/15.
Elf
Adept
Ambidexterity
SURGE II (Metagenetic Imp. (Agility))
Aptitude (Pistols)
Restricted Gear (Muscle Toner IV)
Purchase Martial Arts II with Karma (per OP, Krav Maga and Firefight)
Manuevers: Full Offense
Magic 5(4)
Adept Powers: Improved Ability (Pistols) III
Initiations (3): Adept Centering, Attunement, Item (Guns), ????
'Ware: Muscle Toner IV, Genetic Optimization (Agility)
Agility 8 (12) (+1 for Oxygenater Fluorocarbons) = 13
Pistols 7 (10) (Semi-Auto)
OK, so Agil + Pistol = 23, split 11/12
Dice Pool Mods:
+2 Spec
+2 Full Offense Manuever
+2 Attuned Item (first shot, only one Attuned item bonus per action)
-1 Called Shot ( first shot only, -4 penalty reduced to -1 by Adept Centering)
By my math, that's a 16/16 split.
There are a few variations, instead of calling a shot, you can move into Point Blank for another +2 and negate the Attacker in Melee penalty with Adept Centering... makes for 19/18.
So... perhaps somewhat borderline cheesy, almost certainly overspecialized, but yeah, you're a killing machine. With Pistols.
