Colt/Walther Gold Cup front sight replacement

The factory front sight on my Colt/Walther Gold Cup isn't quite tall enough, and I like fiber optic sights anyway, so I'm going to replace it. Most of my shooting is at 10-15 yards. The rear adjustable sight is pretty much bottomed out and I'm still hitting just a bit high; if I drop the top edge of the front sight below parallel to the top edge of the rear sight, I'm able to hit at point of aim. Same story more or less with higher velocity bulk stuff and Wolf target ammo, although they do shoot to a slightly different impact point even at that short range. As I measured it, my factory front sight is .125 wide, and as close as I can measure, about .185-.190 tall.

Dawson's webpage lists scads of sizes for a fiber optic front sight. I need to go taller to drop the point of impact. The width of the front sight is fine, but I could probably be okay with a sight a bit narrower if I had to do that to go taller. The tallest they list for a .125 wide sight, is .200 tall; if I go .115 wide, I can get .210 or .230 tall. I'd like to end up hitting at point of aim while at least several clicks away from either extreme on the rear sight.

I'll be calling Dawson Precision with the following questions, but I also thought I'd seek the collective wisdom of the RFC brain trust:

How tall do you think I need to go on the front sight to hit at point of aim while somewhere in the middle of the rear sight adjustment range?

The .125/.200 sight is listed as "ramped serrated"; the .115/.210 and .230 are listed as "Patridge serrated". What's the difference, and whatever that difference, will it really make any difference to me as I'm looking down the slide at my target?

As I mentioned, I'm fine with the amount of daylight around the front sight in my sight picture. Are there any generally applicable considerations about whether narrower or wider is better for that front sight, or is it completely a personal preference thing?

Again, I'll be asking all this of Dawson Precision, and of course I'll reach my own conclusions in the end, but I'd like to have an informed opinion, and where better to get informed than the boundless knowledge and infallible judgment of you all? ;)

JEC, how did this turn out. Which sight from Dawson did you buy? I bought the .185 since I followed their measurement suggestion, but it is not tall enough. My rear sight is bottomed out and I am still much too hight.

I thinking of the .200 sight next myself, but figured I would see how your project turned out and get your experience before I bought another sight.

Thanks

Yes.. I measured .185 on my pistol 's OEM front sight too. That's why I bought the .185 from Dawson in the first place. But it shoots 3 inches high from my point of aim (center of target) with my rear sight in the middle of adjustment range. I am using the red dot from the fiber of the sight of course. Not the top edge of the sight.

I used the calculator from the Dawson web site and followed their direction. We will see how it goes.

Ok. I finally was able to try my new Dawson sight today. This is the .230 version. I can definitely get my groups centered to the target with the .230. But it does take a few more clicks with the rear sight than I prefer. I think I am at 15 clicks from fully bottomed out.

I am thinking the .220 would have been better. Maybe... just maybe the .210.

I am going to live with it for a little bit and see how it goes.

Interesting.......I've purchased the Dawson .185" sight but don't have it yet. Parts are hard to get up here and take a while to arrive. I'll post my results when I have it set up. I wasn't having any issues with mine shooting high with the stock front sight, so we'll see.

It will be interesting to see your results. I may not have been shooting quite as high if I was using a 6 o'clock hold. But when I put the red dot on the center of the target, I was definitely high.

It will be interesting to see if your pistol behaves the same. Or if it was just mine.

It took almost 3 months, but I received the Dawson front sight today. I have it installed already (it was very easy) and the red locktite is setting. I'll have the pistol to the range on Sunday and give a full range report. For anyone interested here's some pic's on the installation:
1) Use the provided Walther allen wrench to loosen the front sight grub screw. My pistol came with a plastic baggy that contains the barrel thread protector wrench and 2 allen wrenches. The smallest allen wrench is for the front sight grub screw. Once loosened, my sight required a light push to remove it. I removed it from left to right.
2) The Dawson sight goes on from right to left and fit snug to about 1/2 way on. Just a couple of light taps with the Dawson provided tool to seat it half way in the dovetail. I dabbed some red locktite on the bottom of the front sight before tapping it home. There are 2 grub screws in the Dawson sight, just use the provided allen wrench to snug them up and thats it. Before starting I used a red sharpie to mark the centre of the slide. For anyone wondering, there are complete detailed instructions provided by Dawson and this was a very easy installation.

I have my pistol sighted in. Only took 1 click of the windage adjustment to centre the group. Target on right was using the centre of the bullseye as my point of aim, however I have all my pistols sighted in for a 6 o'clock hold and this pistol was set for a 6 o'clock hold with the standard .185" tall front sight. I did not touch the elevation adjustment. There may still be 1 click of elevation adjustment left on the rear sight. Target on the left is the best of the rest (of 150 rounds) using a 6 o'clock hold. I'm happy with the results. A taller front sight might be in order for a shooter who's point of aim is the centre of the bullseye. These targets shot at 20 yards. Something else that may help is to make the rear sight leaf a 2 dot. I used a white fine tip Sharpie paint pen and made my own. It certainly helps.
Edit to add: sorry the pic's are sideways, I've tried fixing it to no avail.
