My favorite so far is CGW?s thin aluminum w/ grip tape. But I just purchased a set of CZ Custom?s compact checkered aluminum grips. Haven?t had a chance to shoot w/ them yet but they feel perfect in my hand. I also have a set of LOK thin grips which I like. And a set of factory wood grips. The wood ones are the classiest by a large margin. Unlike my ARs, which all wear the same furniture, the CZs I own all have different grips on them.
I have small hands so most grip options are to thick. The thinner they are the better I can usually shoot the gun. I don?t like palm swells of any type. Especially the factory rubber grips.
