Not a Combat Commander, but several years ago I had a Colt Series 80 Government Model and had a trigger job done on it. The factory plastic trigger was replaced with a Wilson trigger and the spur hammer was replaced with a Wilson round commander hammer. I'm not a fan of light triggers so I specified a 4.5-5.0lb pull weight. The result was very good, IIRC; a nice, clean break without being anywhere near a "hair" trigger.
I'll echo the advice that you may want to wait and break the trigger in a little before having a trigger job done, if you haven't done that already. Fire a few hundred rounds and do some dry fire practice, then re-evaluate.
If you do decide to get a trigger job done, make sure to use an experienced, knowledgeable gunsmith to do the work. You don't necessarily have to go to one of the more famous/popular/big name gunsmiths, but you don't want to skimp or cut corners, either.
