    Provides excellent contrast to fiber optic front sight

    Excellent rear sight. The U notch makes for easy acquisition of the front sight. It provides outstanding contrast in a low profile sight, ideal for a carry gun.

    Best sights ever

    10-8 has the best pistol sights I've used!

    Very shallow

    SIght is good quality and installed easily. The .156" size is the way to go. However, the sight is VERY small with a shallow sight notch. If your used to a Warren/Sevigny type sight picture you will not like this sight. At speed I found the shallow sight picture difficult to work with. Not a fan of the U notch, especially with such a shallow notch.

    Glock 43 rear sight

    Pretty good rear sight overall, a .156 notch paired with a Bigdot XS standard G43 front sight and it works perfect. My only drawback is that on the G43 the rear sight looks really disproportionately narrow mounted on the slide.

    Typical 10-8 Quality Product

    If you shop here and you shop here enough, then you know your high expectations will be met.

    Awesome rear sight

    Edges aren't sharp like Trijicon's. Wont dig into your skin. Fast sight acquisition.

    quality finish and machine work

    Nice build quality and finish. Slightly small on a 43 slide. I think the larger notch would probably suit most people better. Likely the perfect size for the 42

    Great Performance Enhancement

    I'm a dedicated 10-8 user, so now my G43 has the same sights as all my other Glocks! A must have...

    Excellent replacement

    As always 10-8 has provided me with an exceptional carry sight. I use their sights exclusively on all my carry guns.
