Gearing Question...
Precision on Pistols is good if you have some crit-happy traits (Notably Incendiary Powder from Explosives) but if you don’t then it wouldn’t be my first recommendation. Power is within earshot of useless on pistols, but if you’re looking for burst damage through your Gadgets then I guess you could make Power work. Honestly I’d just stick with a Rifle and stack Power, Toughness, and Vitality for a Gadget build.
It’s hard to make gadgets work in a pistol build imo (granted I don’t like gadgets that much, so I may be biased).
If you’re going for burst with gadgets and pistols you’re kittening yourself I’m afraid (giving up all the survivability and utility that elixirs offer to end up with sub-par burst compared to most other classes).
You could use gadgets mixed with turrets for control in more of a ‘bunker build’ (net turret, bathering ram, slick shoes, …) with pistol/shield.
Works very well in sPvP, but I’ve never tried it in PvE or W3; it would lack the mobility that is often so important there I think.
Gear-wise I tend to take power/precision on jewels at least, even though pistols scale poorly compared to most weapons, it still offers more than the alternatives I feel.
Power scales better on all weapons then condition damage. No exceptions.
