Fits 1911s with front sight dovetails machined to Novak specs (.330"wide x .075" deep x 65 degrees), including some Colts, Baer, Ed Brown and others. All 1911s require a front sight with correctly dimensioned and engineered dovetails to fit properly. The best front sight on the market is made by Dawson Precision and I am pleased to offer it to compliment my rear sight product line. The DP night sights are machined from hardened steel and equipped with a green Trijicon tritium lamp, surrounded by a white ring to enhance daylight visibility. They are offered in heights of .170", .180"and .200"; all with a width of .125".
With proper installation these sights will fit 1911 pistols with the Novak front dovetail cut including:
Some Nighthawk models
Certain Colts that have the Novak front sight cut, like the Wiley Clapp pistols, please compare your slide to the pictures to determine if you have the Novak pattern front dovetail, or the C-More pattern or the Heinie pattern.
NOTICE - When you receive your new tritium sight, take it into a dark place and confirm that it glows in the dark. If it does not glow, I will exchange it, prior to installation.
After the sight has been installed, if it does not glow, the lamp has been damaged by installation. You will have to send the sight to Trijicon for replacement.
