I've been looking at doing some more changes to my M1991A1. I found these sights, and I was wondering if anyone here has a picture of a 1911 Government with this particular sight installed. I can't seem to find one. I really don't want to be doing any milling on my pistol. If my research is right, this should be a drop-in on my M1991A1.

I’ve seen Colts that weren’t cut for regular Novak rear sights but had these Novak sights on instead. While the functionality is the same, these sights do look weird sitting on top of a regular slide.

My suggestion is to get a rear sight that is retro looking but high profile and has good sight picture. Something like the Harrison.

While Novaks might not look as classic as other sights, they make up for it by being easy to see and very tough. The previous owner of my 1991A1 sent it off to Novak for slide cutting and sight fitting.

I’m not talking about Novak-cut Novak sights. I’m talking about the Colt-cut Novak sight that the OP is talking about. It looks goofy sitting on top of the slide.

Yes, my FLG calls it the "doorstop sight" but it has some good points:
1. It fits the GI dovetail, saving a hundred bucks of milling machine time and leaving your options open if you change your mind again.
2. It gives a "barn door" sight picture, good for actually aiming the gun.
3. It should be very durable, lots of iron there. My King National Match was with me for years but it eventually cracked in half from recoil.

Totally agreed. However people tend to be sensitive to certain looks and I just wanted to give the OP a heads up on using that Novak rear sight with the Colt Cut would give the gun a funky look for just in case he might find the final appearance or to his liking.

If the OP were to truly wanted a Novak rear without spending money having the slide machined for the Novak cut and make the sight sits a hair lower then the Colt-cut rear is the way to go.
