Just wondering but I have 2 New Frontier ,the 45colt and the 22mag/22lr convertible.They both have the adjustable black rear sites and ramp front blade.I think the 45 colt front blade is a bit narrower--more to my liking.Im having a hard time getting a sharp picture of the edges in the rear site and of course when shooting at distances of small targets the front blade seems to thick to get a precise alignment.Any suggestions? Ive heard of Eliason and bowen rear sites?Or the White outlined ones?

All Colt handguns used the same rear sight, and the same rear sight cut.

The standard Colt sight is the Accro, and on the Gold Cup and as a special order, there was the target-grade Colt Ellison.

Available rear sights for Colt handguns are the Millet and the factory Ellison.

There may be more, but those are the ones I know.

The Millet comes with a variety of inserts for the blade.
You can get a plain black target blade, a fancy white outline version, and a two dot version.
Millet make different height versions for the Gold Cup, a lower version for standard 1911 autos, and a standard version for revolvers.

Millet sights run 'about $50.00 or so.

The Ellison is a very good target sight and comes with a large rear sight blade, that's grooved to break up reflected light.
They only come in plain black, as befits a true target sight.
Price is around $115.00.

A cheaper option would be to buy a new Accro rear sight blade, and file the notch slightly wider.
New Accro sight blades are available in plain black and in white outline.
Price is a much more reasonable $12.00 to $13.00.

Accro blades are very simple to install, and either a white outline or filing the notch wider would help.

Price-wise, I'd start off with a white outline blade for my existing sight.

Thanks Dfarris-I noticed your very thorough!!Yeah Im not sure yet if I need a slightly wider slot or a slightly thinner front blade.The screwy thing is once in a while Ill manage a great 25 yard group like yesterday I shot 6 times with the magnum cylinder in the little colt nf and placed them in a 1 3/4" group open sights bench rested with the 4 5/8" barrel. But guaranteed I pick up the gun again and it will open to 4"!! I just feel aiming 6 oclock at the 3" black square in the louzy incadescent light at the indoor range I dont see sharp enough to be that precise.I feel those few good groups I get were shot from instinctive hold rather than aiming!!

Colt rear sights have always had a problem with the rear notch being a little too narrow for a good sight picture.
And this is worse indoors under artificial light.

I'd recommend either the white outline which will give the optical illusion of being wider, or just buy a new black rear blade and filing the notch slightly wider with a needle file.

I would NOT attempt working on the front. That's not necessary, and you always alter the part that's easiest/cheapest to replace if you botch it.
Sight blades for the Accro are a LOT cheaper to replace than a new barrel.

An of course, I'd delicately ask, "How's your eye sight? Need glasses"?

Ha-- I do wear glasses but I can see 2015. Like I said I manage once in a while the under 2" groups at 25 yards but I cant do it consistantly.I think I will try your suggestion of getting a raplacement accro blade from Midway and filing it wider .May also buy the white outlined one too since they are cheap. Thanks Dfarris.

I measured my colt NF, S&W17 and Ruger Flat top rear site notches and they are all .126" wide.S&W sell .126,.146 and .160 width rear site notches for their guns.
