Notify on availability

Description:

Upgrade your firearm with unparalleled reliability and precision.

The 1911 U-NOTCH REAR SIGHT by 10-8 PERFORMANCE is engineered for those who demand excellence in their shooting experience. This fixed rear sight is precision machined from heat-hardened 4140 steel bar stock, ensuring it withstands the rigors of daily carry while providing a clear and precise sight picture.

Key Features:

  • Rugged Construction: Designed for concealed carry, duty, or combat pistols where a reliable rear sight is essential.
  • Dehorned Edges: Fully “dehorned” with rounded and chamfered edges to prevent snagging on holsters, clothing, or gear.
  • Easy Acquisition: The .125" high U-shaped notch aligns quickly with a variety of factory-height front sights, including fiber optic, tritium dot, and gold beads.
  • Glare-Free Sight Picture: The rear face features 40 lpi serrations for a glare-free view in almost any lighting conditions.
  • One-Hand Cocking Aid: The front of the blade has a ledge contour to assist in one-hand cocking.
  • Durable Finish: A hard, manganese phosphate parkerized finish that matches many tactical pistol finishes, enhancing strength and surface wear resistance.
  • Secure Mounting: A hidden setscrew anchors the sight in the slide dovetail for extra-secure mounting and resistance to shifting under recoil.
  • Compatibility: Cut to fit the popular Novak Lo-Mount-type dovetail.

Specifications:

  • Material: Steel
  • Finish: Matte black
  • Fits: Novak-style 65° x .500” dovetail
  • Standard Height: .325” high
  • Available Notch Widths: .125”, .140”, and .156”

Enhance your shooting accuracy and reliability with the 1911 U-NOTCH REAR SIGHT—a must-have for any serious shooter.

Brownells USA it's W I D E ! 13/01/2017

This is a high quality sight that I have used on multiple platforms in the past. I had my gunsmith mill the notch wider on past sights and so ordered this one this time around. He had no trouble installing - just slightly oversized which is what you want. I knew ahead of time what I was in store for with that .156 notch since I was pairing the 10-8 rear with a Novak Mega-Dot. I have to resort to this type of arrangement because of my eyesight. It has worked out great for everything up close and out to 25 yards. But Accuracy really dropped off past that and I just have to accept that.

So this is great for fast & close type of shooting but at distance it will be harder to be accurate.
