Oh, my, that's guilding the lilly, in a manner of speaking, but they all sure look nice. No matter how practical the original finish (paint) might be, anything else is bound to look better. I also like the round trigger guard much better than the hooked style on commercial models.
Other than looks, one of the bad things about the painted finish is that it makes the slide slick. I find it had to retract the slide, given that relatively slick finish and the small dimensions of the slide itself. But I've lived with it and I've long since learned to ignore things I don't like if there is enough that I do like. Another short coming is the magazine release. I find it mildly difficult to depress the button because the grip is thick and the release button is "down there." On the other hand, there's little chance of an accidental release.
I've only had the trigger worked on on one or two revolvers and frankly, I guess I'm too insensitive in the hand to think it worth doing on anything else.
Anyone have a .32 caliber version of a CZ-83?
