Sight Pusher Instructions

First steps

The first thing to do with the tool is to wipe off the excess of oil that was applied for storage. Also, it is highly recommended to remove the excess of oil from inside the zip bag. There is no need to re-lubricate the metal parts. The oil the tool is applied with is a high quality and strong rust preservative.

Assemble the tool as shown to learn the process.

Try the tool at home to be sure that it is capable of moving the sights of the guns you plan having the sights adjusted before heading to the range

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. (See tip positioning recommendations below).

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 needed.

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.

Sight installations

The Universal Field Sight Pushers are not designed to do sight removals or installations. However, they are very useful to give the finishing touches when doing a sight installation using the hammer and punch method.

In the following video we explain this process:

Interchangeable tip substitution

The tips can be changed with ease if the following procedure is followed:

1.  Place some masking tape around the tip (not required if the tip is going to be discarded).

2.  Using some pliers, grab the tip with enough force to avoid rotation but being careful not to damage the tip.

3.  Twist the knob counter-clockwise to unscrew the tip.

4.  Place the new tip and screw it in place. Finger tight is enough.

Interchangeable tip selection

The correct tip for the job can be generally chosen by the following rule of thumb:

  • Brass tip: For most sights that are secured in place by a tightening screw or Glock polimer.
  • Steel tip: For sights that are friction held in their dovetail.
  • Reinforced Tip: For sights that are very tightly friction held in their dovetail. Please be aware that this tip requires the use of the Protection Plate.

Tip positioning

To correctly push a sight, tip positioning is important. With a good positioning, the sight drifting process requires less force, and therefore, the chances of damaging the gun diminishes.

Best results are obtained when the tip is placed the lowest as possible in the centermost position in the dovetail. See the following examples:


Convenient way to carry masking tape

For shooters that don’t carry a roll of masking tape, there is a simple way to carry enough tape to use the tool many times. This can be accomplished by doing the following:

1.  Find an old plastic card. Cut a rectangular piece that is wider than the masking tape that is pretended to be used.

2.  Roll enough masking tape around the card piece.

3.  Store the card piece with tape in the same place you store the tool.

Broken tip removal

If proper precautions are followed, it is rare to break one tip. But, if this does happen, broken tips can be easily removed as follows:

1.  Secure the drift screw, tip up, in a vice.

2.  Using a center punch, leave an indentation in the centermost position of the broken tip (fig. 1). Do not indent more than required. This will stick the broken portion inside the screw. To ensure the best centering, the use of a transfer punch with a diameter of 2,5mm (3/32in) is highly recommended.

3.  Make a small hole using a drill (fig. 2). A bit of diameter 1,5mm (1/16in) is recommended.

4.  Place the tip of a screw extractor in the hole (fig. 3). Turn it in a counter-clockwise motion and remove the stuck piece (fig. 4). An extractor with very fine threading is recommended.

Alternatively, a mini Torx, small Allen bit or an iPhone screwdriver might be used to grab and remove the stuck portion (fig. 5).
