Your Browser is OutdatedQ&A for TruGlo Tritium Pro Handgun Sight Set for Walther CCP — 3 Questions & 3 Answers
See Review From Jeff of MO Dated May 25 2019. I posted that review. As an update, I have since reworked the rear sight and after about an hour of grinding, filing, honing, etc, I was finally able to get the rear sight to work with the adjustment screw. Be advised that the front sight provided with this set is the same height as the tall front sight supplied with the CCP M2. I finally gave up on these sights as I need the short sight to get point-of-aim and point-of-impact to match at 25 yards. Just too much work to make these a viable solution in my situation. I went back to the stock sights so as to not shoot 4" low at 25 yards. I still want night sights, but not at the cost of accuracy. Your mileage may vary.
Not easily, not without modification, and not without a sight installation/adjustment/removal tool. I was able to modify the base of the rear sight to fit the dovetail cut in the slide, but the sight still fits too tightly to use the windage adjustment screw. I removed the screw and set the rear sight in with a Universal Pistol Sight installation/adjustment/removal tool I bought on ebay a while back when I needed to install sights on my Glock 42. I decided to try these since I was having trouble locating Night Sights for the CCP M2. Even Walther's website says these fit the CCP M2 and the CCP. Well, not easily. I have read where others have taken their sights and pistol to a gunsmith to have them installed and they report good results. YMMV.
No, your rear sights would no longer be windage adjustable.
