Sight Adjustment

This tool is designed for hand operation only. The use of wrenches or any kind of lever can exceeded operational limits of the tool.

> Optional but recommended preparation: Put some drops of oil at the dovetail of the sight. Let the oil flow into the dovetail and then clean well the excess from the outside with a rag or piece of paper. This will ease the tool operation.

1.    Assemble the tool and decide in which way will be mounted on the pistol. This can be consulted in the plate with nuts. Also decide which tip is the most appropriate.                    

2.    Unload the firearm. Place an empty magazine, rack the slide back and hold it there using the slide release. Do not remove the magazine. If done so, the slide may close during manipulation of the firearm and the tool will damage the frame.

3.    Place masking tape in both sides where the tool will touch the slide to avoid scratches.  

4.    Place several layers of small patches of masking tape where the tool will push the sight.

5.    If the sight features a tightening screw, loosen it now. 

6.    Slide the tool from the back with care. Avoid hitting any part of the firearm not covered in tape.

  

7.    Pre-tighten the tightening screws. Check that the plates are perpendicular and straight regarding the firearm.

  

8.    Finish centering the tool using the tip of the drift screw. Place the tip so it can push the sight properly.

9.    Pull down on the tool to remove the slack from the drift screw before the final tightening. This will avoid the tip from walking off the sight and bending itself.


10.    Tighten the two tightening screws as needed without damaging the gun. Make tool positioning adjustments as required.

Do not over-tighten the tightening screws. If the plates start to bend STOP immediately. This is an indication that you are going way too far.  

11.  As an option, a mark can be made with a permanent marker pen to have a reference of the movement of the sight.

12.  Tighten the drift screw and drift the sight as much as needed. Make sure that the tool is not twisting during the process.

Do not force the brass tips. They may snap and leave a threaded portion inside the drift screw. If the brass tip starts to bend or crush, STOP immediately and swap it for a steel tip. If the steel tip also start to bend or crush, STOP immediately. Check the tool assembly or have your sight loosened up by a gunsmith. 

13.  Once the alignment process is finished, remove the tool by untightening the tightening crews.

14.  Remove the masking tape.

15.  Tighten the sight screw to avoid movement (if applicable).

16.  Disassemble the tool and store it in it's zip bag. Store the tool.
