How well regulated are Kimber's fixed sights? Do they shoot to point of aim, or have there been problems with elevation. Also, do you find that different grain bullets make a substantial difference (185 vs. 200 vs. 230)? I know windage is supposed to be adjustable, but I've read it's really difficult to move the fixed sight in its dovetail. I'm trying to decide between a Team Match II (adjustable sights - which I would probably change to Kimber's adjustable night sights) and a Gold Combat Stainless (fixed night sights). I plan on using it for shooting at the range, but I also want it to be usable for defensive purposes. I know that fixed sights are much better for a defensive pistol (more durable, more snag-free, etc.), but I don't want to have problems with point of impact. Can anyone help me out with some suggestions or personal experiences?
