I have a Talo Colt CCO & love it. I don't think Talo has a lot to do with the internal workings/quality of the handgun, mostly just cosmetic stuff. I suspect their name & design is part of the price, as well as they are usually limited runs (only 800 of the one I bought). If Colt had a regular production CCO, I would not have bought the Talo edition, but I wanted the 4.25" barrel & lightweight officer's frame configuretion.
It really comes down to whether you like the pistol. Many folks buy an off-the-shelf pistol, then spend $$$ modifying it. So, if you like the particular mods that Wiley Clapp did, it's worth it!
