sight adjustment
I don't have a special tool, but my method seems to work OK. Place your slide in a Vice that it fixed to the table, I usually wrap the slide with leather as to not scratch the slide when I squeeze it in the vice. Take a hammer and with a brass punch of appropriate size, tap (most lkely bang) the rear sight in the direction you want it to go. You must use a BRASS punch (it's softer than steel) and not a carbon steel one so you don't deform the sight or any other part of the slide.
