After I posted the last thoughts, I had one more. But it had to wait for the morning.
The major drawback for going clone is usually the sights. They are something that is not easily replaced by aftermarket products. The SAR dovetails are something all of their own, the Canik S and P series are replacable with only one brand of sights (if I am remembering correctly), and Witness had a bit more aftermarket, but nothing like the Glock, XD, and so on. If you want to go this way, I do suggest looking into what is available for sights, if you are the type of person who neede to change these out or whatever, as this can be a major sticking point.
One other thought, there was one guy (custom gunsmith on the CZ Forum) who did change out sights, but came to the conclusion that it was NOT worth the cost for replacing SAR sights due to re machining the slide, refinishing, labor, sight cost, and making a gun that was already available for the same price elsewhere.....a true CZ75 with night sights, and dovetails that were supported by aftermarket products.
Does this make sense?
I guess in the end, you need to figure out if the pistol will work for you as is, and not worry about upgrades which more than likely are not available. Reality, it sucks sometimes.....but I can live with my choices and do not feel uncomfortable.
