HARRISON DESIGN & CONSULTING EXTREME SERVICE NIGHT SIGHT FOR 1911 HANDGUN

Sights are not "drop-in" parts, especially for 1911 pistols. There are so many companies, large and small, manufacturing 1911 pistols today and they all have different ideas about dimensional consistency in the sight cut. The only way after-market sight manufacturers can provide you with sights is to manufacture their sights and hold their dimensions on the high side of the range commonly encountered. This means that to install sights on 1911s, you often have to "fit" the sight to the sight cut by finding the surface on the sight that is too big and filing it down until the sight can be installed and still fit tightly. Sometimes it's more than a single surface that has to be fitted.

Features include:

HD-004 / HD-005 rear sights will fit the popular Novak LoMount ® dovetail, which is found on fixed sight 1911s offered by Les Baer, Ed Brown, Colt's XSE, RailGun and Gunsite models, Nighthawk Custom, Rock River, Springfield Armory, Dan Wesson, Wilson Combat and others. My HD-004 / 005 sights will fit your slide with minor hand fitting of the sight, if the correct sight cut is already made; otherwise, your slide will need to have the .495" X 65 degree sight cut machined.
