My new 45 colt CCH Carbine came today!

Looks good, nice coloring - so how well does the CCH coloring wear and what do you do to maintain it?

I have the 45 Colt CCH also. The CCH so far has shown itself to be tough and durable. No marring or scratches so far. I wipe it down with an oiled cloth.
The loading gate is not CCH. It's black steel. It will accumulate a brass appearing smear from ammo being slide into the gate. It's a tough scrub with Hoppe's #9 to get it off. TetraGun works better. I no longer bother. I leave it, gives the rifle additional character.

I agree with leaving the brass smear. I have the CCH in 44 mag and at first, I thought, I should clean the brass smear, but leaving it gives it the look of a veteran! I've done far more shooting with it than I thought I would.
