I once made a dual-hand crossbow gunner, based on the video game character of my username. He had some things that aren't essential to hand crossbow combat, for flavor reasons. He was a Wizard 1 (Abrupt Jaunt ACF)/ Targeteer Fighter 2/ Feat Rogue 2/ Swordsage everything else. He had Crossbow Sniper, Shadow Blade, Dead Eye, and the Targeteer ACF, for 3.5 times Dex to damage. Assasins Stance also gave him 2d6 sneak attack, which is minor, but good for activating Shadow Blade. He had +1 Splitting Quick Loading Handcrossbows of Speed, and a Quiver of Endless arrows. With Dex 34 (as a human), he did 1d4+42 damage per arrow, and with Perfect TWFing, he had 20 attacks. I had some way of getting more, but I can't remember.
