I have a highly customized Kimber (only the frame and slide are original). The lockworks are Nowlin and barrel is Kart. It's a sharp looking handgun. The rear sight is MMC and the front is EGW fiber optic.

Now for the problem. For some reason, the gun shoots about 6" to the right, even at 15 yards. I have to drift the rear sight VERY far to the left (3/4 or more in the dovetail) to even come close to POA. (The front sight is centered in the dovetail.) Maybe I'm "pushing" the gun? But that doesn't explain why the sights on my Baer PII are centered and it's right on target. Besides, why would I be pushing one gun and not the other since both are set up almost exactly the same (ambi safety, thin grips and short trigger). Any ideas?

My first guess would be that you've got too much finger on the trigger, (assuming RH shooter) but if you are sure it's not a "shooter problem" then let's look elsewhere.

You say your front sight is centered in the dovetail. Is the BLADE centered, or is the whole sight centered? Perhaps one leg of the sight's dovetail is longer than the other so it LOOKS centered but isn't?

Either way, try drifting the front sight a little to the right and see what happens.

I've worked on literally thousands of 1911s and I've never seen one that shot that far off center from "mechanical zero." I believe you're going to find that it's either a sight problem or shooter error. (personally, I'm betting on shooter error, it happens to the best of us sometimes.)

HTH!

Check your barrel's muzzle for a proper crown, then go to other things.
Check trigger overtravel.(You could be thumping it into the frame favoring the right side.)
Put a collimator in the bore and make certain that the centerline of the bore is parallel to the line of sight.

It is easy to shoot high with a fiber dot sight by aligning the dot with the top of the notch and not the top of the sight with the top of the notch

Come on, Howard, talk to us!

John Lawson,
Do you really think that crown deformation could cause that consistant a shift in point of impact?

I'd think that a messed up muzzle would affect group size, but I don't see how it could throw a consistant group away from POA.

Like the man said HowardK,
Talk to us! :grin:

Thank you for all the responses. I will check the barrel crown, the trigger over-travel and the placement of the front sight. The top of the slide has been flattened and serrated so the visual piece (lining my front sight up with the center of the barrel) may be off if the serrations are off. It may also be shooter error. The best way to figure that out would be to have a friend shoot the gun and see if his shots are also going right. The gun has been a "PITA" almost from the beginning, but that's another story.

Did you get that Kimber initially at one of the Astro Hall gun shows about a year or so ago.
