Not to my knowledge and I don't think that would be the correct course of action with the Omega. Messing with that trigger is a bit of a nightmare and, if you screw up, you might need to buy the whole assembly. What a person can do (and I am not endorsing this) is disassemble the trigger, then take note of the ridges formed during the casting or finishing process. Lightly honing those ridges, without changing any contact depth or angles, should smooth and lighten the trigger a bit.
My guess would be such work will void the warranty.
