Speaking of sight adjustment, a while ago I knocked up a quick calculator to take my observations at the range and help me determine how much I have to push the sight. But I also wanted it to calculate how much of a turn of the threaded rod on my tool, would equate to that amount, since I have no way of accurately measuring really how much the rear sight actually moves in the dovetail. This way, I can assemble the tool on my slide, snug up the pusher block up onto the sight, turn the handle the predicted amount, and be pretty much spot on.
HINT: IF YOU DON'T LIKE NUMBERS, STOP READING NOW.
I decided to do put this in a shared Google Sheets spreadsheet.
It was the first time I've worked with Google Sheets. If you click the link, hopefully you'll see a spreadsheet. You basically enter four pieces of data, and it will calculate both the rear sight movement, as well as how much fo a turn you need to make on the sight tool. The sheet is protected from edit, except for these four values. The sheet is "live", in that anybody with the link can get to it to use the tool.
The 4 pieces of data you need to enter (GREEN cells) are:
What Range you are observing your target groups (I have been using 7 yards)
Your pistol sight radius (I had been shooting my Glock 48, at 5.63")
How much you want to "move" your target groups, to get them back to center. (in my case, I was seeing about 1 1/4" to the right, so I wanted to move them 1.25" to the left).
If you use a sight tool, you also need to enter the threads per inch of the threaded rod. (in my example, I was moving the rear sight 0.028", or about 45% of a turn of my 16 thread per inch rod on my sight tool).

Since I was at it, I also did one to help me calculate Front Sight Height changes needed, to adjust for observed elevations at the target:

This one works pretty much the same way; enter the range, sight radius, how much you are "off" by up or down, and also your current front sight height. It will calculate the delta needed to "zero" for elevation, and a new sight height for you to buy.
Hope this helps.
