Novak® LoMount™ Dovetail Sight CutNovak Sight Installed

The Novak® LoMount™ dovetail is a somewhat standard dovetail sight cut found on many popular factory-fitted (OEM) and custom platforms. The Kensight® DAS™ (Defensive Adjustable Sights) and DFS™ (Defensive Fixed Sights) are the perfect low profile upgrade for your concealed carry, or combat carry pistols, due to a smooth, thoroughly "dehorned", low-profile exterior. The benefit of this feature is there are no sharp edges to cut hands or catch on clothing during the draw stroke which compliments your concealed carry or defensive style 1911. This particular sight will only fit an existing Novak® LoMount™ 1911 dovetail. If you unsure of your current dovetail configuration and would like to know more about dovetail styles, click the button below.

Standard Front Sights

Add The Optional Front Sight

A front sight with dovetail dimensions of 0.330" (Width) x 65° (Angle) x 0.075" (Depth) has become known as a “standard” front sight in the industry. While these were first seen on 1911 slides with the Novak LoMount rear sight, other OEM manufactures have adopted this same size for their 1911 platform. There are two basic configurations of the “standard” front sight base. One is the “Flat Base” style and the other is the “Contoured Base”. The dovetail dimensions are both the same, so the base selection is a personal preference depending on the profile on the top of your 1911 slide. We recommend that you check your existing front sight dovetail dimensions, before purchasing the standard front sight.

DAS™ Suggested Front Sight Height

The front sight height will greatly vary depending on your rear sight selection. Most of the Kensight DAS˜ (Defensive Adjustable Sights) will require a front sight height of 0.190” - 0.200” tall. We ship most of our DAS sight sets with the recommended 0.200” tall front sight. In some cases your existing front sight may work, but this could limit the amount of elevation adjust-ability in the rear sight. If you would like to learn more about front sight heights, visit our Front Sight Height Guide.

    I customized it!

    Posted by James Orth on 25th Aug 2019

    Risking becoming a "Bubba", I fit an adjustable rear sight (Novak cut) to a Rock Island Citadel 9mm 1911. Filing and also using the dreaded Dremel tool! Your steel is so hard my file wouldn't do much. I lost a set screw. Vibrated out while dremeling. They are SO tiny that it took quite a while to find in my shop! Also, be careful not to lose those micro-tiny springs!! In the end a pistol that shot 5" low at 25' now shoots exactly to point of aim, limited only by my shaky old coffee-infused body. GREAT PRODUCT!! I am going to buy another that will actually fit my Ruger SR1911. Rock Island's cut is "propriatary"-nothing fits right.

    Awesome rear sight raises Ruger 1911SR to 5 shot - 1 ragged hole accuracy.

    Posted by Cameron on 5th Oct 2015

    I wanted to replace the Novac fixed rear sight on my Ruger 1911 with one that was adjustable. The sights were a tight fit and required some fitting but are now seated very tightly. I believe installing them resulted in my gun being zeroed for elevation because after adjusting to correct shot placement to the right I found the gun shooting exactly to point of aim. They were just a little higher than the Novac sights that were original to the gun. This modest upgrade has improved my affordable Ruger, giving it the accuracy of a much more expensive gun and increased my confidence. I'm happy!

    Perfect fit on a Dan Wesson V-Bob

    Posted by Kensight Customer on 20th Jul 2015

    I needed a 0.21 tall front sight (kensight part number 870-121) with this rear sight to get proper alignment. Front sight needed some fitting with a triangle file, but once installed it fit great. The bevel of the front sight base matched the slide perfectly and the stake hole on the sight lined up perfectly with the stake hole on the slide.

    Easy install and tight tolerances

    Posted by Justin A. on 25th Jun 2015

    Dan Wesson Specialist: installed readily with minor fitting removing some material on the leading edge of the sight and bottom, used a brass punch to seat and it is tighter than the factor original I removed. I'll sight it in this weekend, but the fit is great and click adjustment feel very tactile. Thanks for a great product!
