Looking for some advice from some fellow shooters on an issue I'm having with my DW CCO. I took it to the range for the first time and found it was shooting way high (7.5") as detailed here: http://forums.1911forum.com/showthread.php?t=299706 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".
