Basic Gun Safety Rules
1. Treat all guns as if they are always loaded.
2. Never let the muzzle cover anything you are not willing to destroy.
3. Keep your finger off the trigger until your sights are on the target.
4. Be sure of your target and what is beyond it.
PLEASE FOLLOW ALL FIREARM SAFETY RULES. BE SAFE!
PLEASE STORE ALL AMMUNITION AND MAGAZINES AWAY FROM WORK AREA WHEN WORKING ON FIREARMS.
PLEASE WEAR EYE PROTECTION WHEN YOU WORK ON YOUR FIREARM. FIREARM PARTS MAY BE UNDER
SPRING TENSION AND COULD BE EJECTED CAUSING AN EYE INJURY.
IF AT ANY POINT YOU ARE NOT COMFORTABLE OR EXPERIENCED ENOUGH TO ADJUST OR REPLACE THE
REAR SIGHT OF YOUR SLIDE, PLEASE SEEK HELP FROM A QUALIFIED GUNSMITH.
It’s advisable that your work area is well lit and that you have a clean work area. Sweep the floor clean to make finding dropped/
lost parts easier. Be advised that some carpeting may make it difficult to find dropped/ lost parts. You will be working with small
parts and during the disassembly of your firearm; some parts may be under spring tension and could be ejected from the
immediate area. It’s advisable that you cover your work area with an old light colored towel, table cloth, or anything that you would
not mind getting dirty to make it easy to find dropped/ lost parts.
If you do not have a firearm manual for your specific firearm model, visit the firearm manufacturer’s website to download
or request a manual.
Read the firearm’s manual on how to safely remove/ field-strip the slide from the pistol frame.
Remove the barrel, recoil spring, recoil spring guide, and other small parts from your slide/ frame and set them aside in a
safe spot, before using this tool.
The Universal Pistol Rear Sight Tool is designed to adjust or replace the rear dovetail sights for most semi-auto slides. It
is not designed to adjust the front dovetail sights of a semi-auto.
The Universal Pistol Rear Sight Tool is also designed so that it can be clamped/ bolted to a work surface or placed in a
vise for stability.
Lubricate the Universal Pistol Rear Sight Tool, with a drop of light machine oil onto all the screw surfaces, moving parts,
and bushings in the rear sight tool before each use.
1. First step is to lower the tool elevation wheel down to allow you to place the slide under the rear sight pusher legs, to
verify tool and slide clearance.
2. Raise the top slide clamp all the way to the top and make sure that there is a flat plastic insert in the dovetail.
3. Adjust the two slide side clamps away from the center of the tool, to give you enough clearance for the width of the slide.
The two slide side clamps have a choice of two pairs of plastic inserts. A pair of flat inserts for flat profiled slides and a
pair of stepped inserts to fit slides with a stepped slide profiles. The stepped inserts can be fitted with the thickest part of
the insert either on the top or bottom in the slide side clamps, depending on what fits your particular slide the best. The
plastic inserts will help hold the slide in place without marring the finish. You may place some painters/ masking tape onto
the slide itself or on the inserts itself for additional protection for the slide finish.
4. Position the rear sight pusher, so that either the right or left rear sight pusher leg is centered in the tool and is placed over
the highest part of your slide, just in front of the factory rear sight for verifying slide and tool clearance.
5. Place the slide onto the tool elevation wheel with the factory rear sight just behind the rear sight pusher. You will need to
adjust the height of tool elevation wheel for the proper height and clearance. Slowly turn the tool elevation wheel to raise
the top of the slide up to one of the rear sight pusher legs. You want the rear sight pusher legs as low as possible without
the rear sight pusher legs touching the highest part of your slide. Some slides have a crown in them, so make sure that
the rear sight pusher legs will not touch the highest point of the slide.
6. If you are working on a small pocket pistol slide that is not tall enough to reach the rear sight pusher, with the tool
elevation wheel all the way up to the highest position. We have included a rectangle plastic riser insert that will work on
many modern pocket pistol slides. If the included spacer does not work with your particular slide, you may improvise with
any plastic, cardboard, wood, or metal (aluminum) scrap that will raise your slide to the proper height to engage the rear
sight pusher.
7. On each side of the sight tool are witness windows machined through the sides of the tool. This will allow you to verify the
clearance of the rear sight pusher legs and the top of the slide. You want at least two business card thickness of daylight
clearance from the lowest part of the rear sight pusher legs and the highest part of your slide.
