My calculation in the above thread was a bit off due to my short changing the sight radius. Based on my corrected calculations using a 5.25" (Commander) sight radius, it looks like I need another .04375" of height over the factory installed .150" sight. My calculation looked like this:
(Amount of error X sight radius) / Distance to Target = Correction Required
(7.5 X 5.25) / 900 = .04375
Seemed like a .195" high sight ought to do it.
I tried calling DW last Monday and got the "everyone's at SHOT" story--"try again after the 24th". I went ahead and detailed my experience in an email and attached the photo showing my target.
Much to my surprise, I got an email this evening from Keith at DW saying:
"I have never seen any of our guns shoot more than 4” high at 25 yards. To account for your impacts you would need a .080” taller front sight. This is impossible. I would suggest trying again with standard ball ammo."
I shot the group in the linked thread with 230gr ammo and shot similar groups using 200gr SWC ammo.
Is this "impossible", or am I losing my "enlightenment"?
Edited to add: Since DW doesn't appear too interested in helping me solve this issue, my next step will be to take the sight off of my Valor (.190") and see if it gets me close. If it does, I'll be sure to email Keith a picture of the "miracle".
That's horse*****, if you pay THAT much money for a gun, they should fix it no questions asked. If you've not had several people test it, do that and see if they have the same results. Also, try a few different manufactures of ammo. If it's still off I'd raise hell. If it's truly the pistol, DW needs to fix it, on their dime. There's no way I would pay my money to try different sight combos just to get the right one!
Or, you could take this "opportunity" to just put new sights on if that's what you desire.
Nope, shot correctly. Just mentioning the rear sight because it might be too tall. When I had a .375" rear sight on one of my Springfields, it shot 6" high. When I changed it to a .325" it was dead on.
Got the .375" 10-8 sight since it was recommended, but learned that isn't the case.

Yep, and email being what it is, I probably took Keith's "impossible" comment a little too personally. I'm sure he deals with a good share of inexperienced folks who aren't necessarily fanatics like most of us here.
Tyler,
You hit the nail on the head. I talk to lots of people in the gun business and they talk to all kinds of dingbats all day long. It may not be right, but Keith may assume (wrongfully) that you are a wingnut that is complaining about a POI issue when you couldn't hit a barn a 5 foot. Get in contact with him and explain in detail you issue in a pleasant manner.
just checked my Guardian, and it's a .325" rear sight with a .140" front sight, which is the same as i'm running on my SA Champion. my Kobra Carry uses a .325" rear and a .180" front sight.

Well, I took some real measurements with the sights off of the slide and found my front is actually .140" and rear is .325". Measuring sight height on the slide is hard. :dunno:
Decided I needed to take another trip to the range with some 230gr ball ammo and try the front sight from my Valor which is .190". The .190" sight shot pretty close to POA, but still a tad high.
Grouping isn't quite as tight due to the bright sun on my white target and the distractions from the concealed carry class going on at the range this morning.
After discussion with Keith at DW, the slide is in the mail for installation of a taller front sight. Thinking a .195" would be spot-on, but don't know if they make one.

Just got my slide back from DW. They installed a .180" front sight. I went back and measured the front sight on my Valor and it looks like it may be .180" vs .190" like I thought. All depends on how you hold the calipers. Best bet is to do like Quack suggested and use the other end of the calipers with the protrusion to check height on the slide.
I took it out to the range and all is good. Still maybe an inch or so high, but I can live with that compared to the previous version.
When I first bought my CCO I found it shot over 6" high at 25 yards. Sent it in and they replaced the front sight with the correct post. The one they had installed was far too short. Shoots point of aim now. :wavey:
