Darting Weapon (D20 Modern Feat)
From D&D Wiki
Your melee attacks are incredibly fast.
Prerequisite: Combat Expertise, BAB +3.
Benefit: At the start of the combat round, you may subtract a number from all melee attack rolls and add the same number to your initiative check. This number may not exceed your base attack bonus, and the effects last until the start of the next round. You may not make ranged attacks this round.
