Kimber sight woes Shoots too high...

On my Kimber Stainless II (not target sight model), I installed a dawson precision adjustable rear sight, and their .180 tall fiber optic front sight. It shoots 3-4" high at 25 yards with the rear sight all the way down. I am thinking that a taller front sight is the solution. Dawson has a .245 tall "rimfire" front sight. Would that be way too tall? Is there any other brand that works in the Kimber front sight cut that is a good height?

Try here to figure out what you need for a front. Several formulas and videos address the sight height issue.

Thanks for that!

So according to this:

http://www.brownells...ne_Sight_Height

With a 6.75" sight radius, I need a 0.02625" higher front sight, in other words a 0.20625" tall sight.

According to my further calculations, a .200" tall front will hit 0.833" high. What I really need is a .210" front and then I can adjust with the rear sight. Sigh, I've never seen one of those.

OR, I can get a .245 front sight, and adjust the rear sight (.245 - .20625 = ) 0.03875" up. Hmm, bringing out the calipers to see if that's possible...

EDIT: Yep, not a problem at all

If you're using a solid front sight, you can get the taller front sight and slowly and carefully file the sight to the desired hight and width. A touch of gun-kote flat black, install, and GTG. Go slow, measure after every file stroke, keep the top perpendicular to the sides.

It's a fairly cheap piece to work on so if it goes to crap, you can toss it and learn from the experience, and start over.

Dry Firing and Practicing Sucks. Embrace the Suck.

Ugh, I just found out that the .245" sight only fits on the .22 kimbers

Where the heck do I find a front sight around .210"?

Use one of the sight blanks brownells sells , cut it down a little at a time, then if ya need a fiber optic=
cut a slit in it leaveing enough room say 70 thousands and drill the sight with a 1/16 or smaller drill
and put in the fiber.
