A newbie question on 1911's. I have a 1911 pistol with fixed rear sights and wanting to replace with a Novak extreme duty adjustable sight and was wondering whether there is still a need to cut the slide.

My friend tells me that my existing fixed rear sight is already a novak cut and replacing with an adjustable novak cut sight may simply be a drop in.

If I already have a Novak cut rear, does that mean that any other rear sight that is of a Novak cut design will simply drop in or are there different dimensions still for each Novak cut ?

What kind of 1911 is it? Springfield and RIA's "Novak" rear cut are slightly different from the actual Novak cut. The dovetail angle are slightly different, but can be remedy with a few swipe of the file.

The Extreme Duty Novak will require machining.

Have you ever seen that rear sight in person? It's huge.

Call Novaks. (304) 428-2676

Since there are plenty of 1911 sight cut's out there, here's the different dimensions that i have come across.

Novak is pretty much the standard cut for 1911 sights.
Front: 65 x 330" x .075" (have also seen .060" and .070")
Rear: 65 x .500"

Springfield used to use the standard Novak rear cut, but it's changed since after ~2002 to a smaller cut.
Front: 60 x .330" x .078" (this info is from Springfield)
Rear: 65 x ~.490"-.485" (this is just a smaller cut in the dovetail, which requires filing down the sight to fit)

Armscor (RIA Tactical and Citadel)
Front: 60 x .330" x .085"
Rear: 65 x .487" (similar to Novak, but needs to be fit like the Springfield.)

Dan Wesson uses a combination of standard Novak rear and Springfield front:
Front: 60 x .330" x .078"
Rear: 65 x .500"

Kimber has it's own sight cuts.
Front: 65 x .330" x .070”
Rear: ??? don't know, but there are sights specifically for Kimber's

Smith & Wesson has it's own sight cuts. I haven't looked into what they are.

For the Novak Low-Mount sights, it's not just the dove-tail, but you also have a flat behind the dovetail that is lower than the top of the slide.

I use a 65 degree dove-tail cutter for all of my sight installations (front and rear), which matches the Novak sights.

I did not realise that a "novak cut" can have different variations.

I have a Para Ord Todd Jarrett edition S16-40, which currently has a fixed novak sight installed. I bought the firearm from my friend who told me that he replaced it rear, which used to be an adjustable novak sight which could be adjusted with a set screw for elevation and windage by drifting the sight left or right.

There is only one cut for a genuine Novak Lo-Mount rear sight.

The variations are for the many Novak-Style rear sights.
