HD-003 S/U Retro rear sight

Retro rear sight for USGI spec dovetail

The Harrison Design "Retro" rear sight offers a rear sight that does everything that sights costing many times more do, in a package that fits the original 1911 USGI spec dovetail. Like all Harrison Design sights, the Retro has a flat rear blade surface with horizontal serrations machined at 50 lpi to eliminate glare. The outer corners are rounded to eliminate snags and abrasions. The front face is designed to allow one-handed manipulation of the slide. With an overall height of .320" and a notch measuring .140" x .125", the Retro sight offers a sight picture that allows adequate light in to make rapid sight alignment possible, while not being so large that your ability to make accurate shots is compromised. Originally designed by Ted Yost with design enhancements by Harrison Design, the Retro is the perfect rear sight whether you're building a "Retro" custom or looking for a full-featured, moderately priced rear sight that you don't need special machining capabilities to install.


The HD-003 Retro rear sight is now available with either a square notch or a U-notch. Same price - twice the goodness!
