Hi Johan......welcome to TFF!
I've never shot a "Special Combat".....however, according to the specifications it sounds like it was built and tuned (by Colt's Custom Gunshop) for just the kind of use you want it for. It sounds like it should be pretty much "competition ready".
However, if you're like me, when you get a new gun (no matter how good it might be), there are always a "few little things" you'd like to change.
All I can recommend is that when you get it, shoot it a bunch and see if there any changes you'd like to make.
