1911 front sight

Back when I got my Remington 1911 Rs ( 2012) the original front sight shot low at 25 yards and I starting reading up on this and Remington actually had a lower sight @ .062" : the Original front sight was .188" Well long story short I finally got the lower front sight on it and now it shoot high ( by + 3.5" from POA )
So playing with the math...... If I reduce the original high front sight down to .158" that should put my impact at + 1.5 from POA
The Keyword is "should"
So I'm throw this out to the forum to get you opinions. Does this math seem correct?
I know I know I can do it exactly like my Flintlocks....... Go to the range with a file ...Shoot, File, Shoot, File etc

My method................shoot and file. The charts and geometry of doing the math to calculate the difference almost never works for me. Probably one of the reasons I am such a fan of adjustable sights.

Load up some 230-grain bullets with a 700 fps starting load of medium-speed pistol powder and see if that doesn't correct it.

Ian,
I did: 4 Gr BE with the Lee 230 RN these shot about 2" lower but to the left!
I would splurge for Novack Adjustable rear however Remington cut Their dove tails real small and a 60 deg So I would have to have them milled!
Yes I can do it with files but it is stainless and It is a big cut! ...I'm still thinking about it...but I too only have 60 degree Dovetail files Novack is whily
using 65 deg angle

Shucks. I don't think I've ever seen a 65⁰ safe-edge file for sale. I think your math makes sense, to answer your original question but agree with you and Rick about file-shoot-file with a box of your favorite load being the most foolproof method.

Yes I know you guys are right!
The hard way is always the best! Just thought I could do a bit of filing in the shop first to move it a bit

Ian,
That is their shtick! Novack uses 65 Deg so Your only quality option is to send them your slide! They do do a great job and do it pretty fast!
Just bugs me because it should be something I can do by hand

I'd look at filing the Novack dovetail to 60 degrees. Then again, I'm stuck inside for most of the next week and looking for things to do. Good thing I'm not a welder/machinist, there's a Springfield 1903 action on the shelf that would make a neat little 250 Savage if the action were shortened.

I wouldn't put any money against him having made one or two in the past. It's really not that difficult once you get the carburizing part worked out.

AxC/B=D

a is change in sight height
b is distance from sight to eye
c is distance to target
D is the change in POI

if your changing the front sight, raising the height lowers the impact.
if the rear sight,,,, raise is raise and lower is lower.

In the, "For What it is Worth" category, I recently sent a slide off to Novak to have dovetails cut and Novak sights installed. They did a great job, the turn around was quick and the sights are excellent.

Jim, an old world gun maker likely would have made his own file.
Where do you think I got all my 60 deg dovetail files...I didn't buy them
Actually I have a number of safe bottom 60 deg dove tail files in different sizes & cuts I made out of new 3 sided files ...but I didn't buy them, I acquired them from Sandvik tools in the 1970's and 80's ;)

Yeah I'm thinking I should do this already! If you don't mind me asking how much did they shop work cost on the slide?

Those three sided files make a great pipe I.D. deburring tool once you grind off the file teeth. I stone all three sides.

I used to work with a guy whose dad was a machinist mate in the Navy before, during, and after WWII. He said that his dad showed him how to make these scrapers/deburring tools. Underway they never seemed to have the proper babbitt bearing scrapers, so they made there own out of triangle files.
