If your weapon is equipped with exchangeable rear sight blades, the elevation- and
windage adjustment can be done by hand. This can also be facilitated by the use of a
coin.
A slight pressure on the upper side of the sight, done by e.g. the thumb, can relieve the
elevation adjustment screw during this slight adjustment.
The windage adjustment screw is located on the left side. Elevation and windage
adjustment are effectively influenced by means of a micrometer-click screw. The sight
physically moves .0016"(.042mm) with each click.
The adjustment values for elevation and windage vary slightly for the different calibers,
barrel lengths and loads. For a 6" barrel and most target loads in caliber .38 Special,
the change is approximately .394" (10mm) at a distance of 82' (25m). The exact values
for your weapon have to be determined for each load.
8.3.1 Rear sight blade replacement
At the upper side of the rear sight notch, a .059"(1.5mm) Allan screw is located in the
rear sight blade. This screw is loosened counter-clockwise with the included Allen
wrench until the rear sight blade can be taken out from the back of the rear sight notch.
The included rear sight blades are marked on the inside by numbers from 1 to 3. The
numbers correlate with the following rear sight notch (width).
#1 - width .134" (3.4mm)
#2 - width .138" (3.5mm)
#3 - width .142" (3.6mm)
Changing the rear sight
Tighten the screw after the insertion of the new rear sight blade. Occasionally check
this screw to make sure it remains secure, as well as the rear sight blade, while
shooting.
