There may be $600 of custom benefit over other CZs, but I doubt that I have enough skill or natural ability to take advantage of that extra benefit.
That is a gorgeous weapon, however.
(I spent almost that much on a SIG X-FIVE in .40, and I can't shoot it worth a crap. It's not the gun -- as it drives tack from a rest. Unhappily, I shoot other, cheaper guns far better. It nakes me want to cry.)
