I agree with Both Joe and Chuck. Slightly more with Chuck if you want to save $. IC/full is also more versatile than IC/Mod, especially in smaller gauges, IMO.
I'd like to throw in a small point here, we always refer to the triggers as front and rear and they are. However, they are also right and left. Some folks, new to SxS shooting, are completely bewildered as to which trigger fires which barrel. A quick look at the slots in the trigger plate would(or should) make the answer clear. As I said, I just threw that in. Feel free to throw it out.
