There are many types of sights being made today, but what type of sights work well on a self Defense (SD) handgun? I love my Glock handguns but the one thing I do not like are the plastic sights. So that is one of my first upgrades that I want to change. I really like the XS Sight Company as I feel they have very high quality sights at a somewhat reasonable price. I was looking on Amazon a while back and found a new style of XS Night Sights that I thought might just work for me and besides they were at a very reasonable introductory price. So I thought I would give them a try. I bought three for my Glocks, my Glock 19, 30 and 20. Most of my discussion will be about my Glock 19 (9mm), so let’s talk about it.
How Do We Install These Night Sights?
I made a product review on a VISM Sight Pusher back in 3/14/2022. The VISM Universal Pistol Rear Sight Tool is designed for the removal, installation, and adjusting of windage of dovetailed rear sights for most Semi-Auto Pistol slides. The Universal Pistol Rear Sight Tool works with many types of semi-auto slides: full, compact, subcompact, and pocket-sized semi-auto pistols. The base platform is adjustable for height, to get your slide and rear sights at the proper height for the rear sight pusher. Includes one bottom spacer for some pocket pistol slides for proper height alignment. The multiple vertical and horizontal clamps secure various sizes and types of semi-auto slides in the tool. The adjustable top brace with a plastic insert to secure the slide’s vertical placement on the base platform. The adjustable side braces with plastic inserts secure the slide’s horizontal placement on the base platform. Includes two sets of side plastic inserts: a pair of flat inserts and a pair of stepped inserts to fit a wide variety of slide profiles.
Old Rear Sight Removal –
- Field-strip your handgun
so that you only have your slide (barrel and spring removed).
- Place your slide in the VISM Sight Pusher so that you are pushing your old sight from left to right.
- Begin to screw the sight pusher a little at a time until your old sight comes out.
- Clean out the sight dovetail to remove any excess grease, etc.
- Field-strip your handgun
Old Front sight Removal –
- While the Glock is field-stripped you can also remove the front sight, it is a screw-on using a 3/16″ nut,
the screw is on the inside of the slide.
- Get a 3/16″ nut driver and remove that flat screw on the inside of the slide and the front sight should come off.
- Get a cloth and wipe the slide hole , inside and out.
- While the Glock is field-stripped you can also remove the front sight, it is a screw-on using a 3/16″ nut,
New Sight Installation –
- Remove the new sights
from the packaging and see what you have to work with.
- You should have a front and rear sight, an Allen wrench for rear sight windage adjustment, a nut driver for front sight installation, and some Loctite (Blue so it can be removed if necessary).
- I always use my own Loctite (Blue 242) so I know exactly what I am putting on.
- Remove the new sights
New Front Sight Installation-
- The front sight should have the same flat screw that the old sight had.
- Unscrew the screw in the new sight
and put a small amount of Loctite on the screw.
- Place the front sight over the hole and put the screw through the hole and into the front sight. (Make certain that the front sight is on the correct direction).
- Using a 3/16″ nut driver, tighten the screw snugly, but not over-tight. Also make certain that the sight is straight and not slanted.
New Rear Sight Installation-
- Reposition the slide in the sight pusher so that the sight pusher is pushing the new sights from the right to the left.
- Set the new Night Sight in the dovetail
and slide it to the right into the dovetail. It should slide into the dovetail 1/4 to 1/3 of the way into the dovetail, or further fitting will be required.
- Further fitting means to remove some of the bottom of the sight using either a sharpening stone or a good file. This needs to be done very slowly, removing some of the metal a little at a time. Then try it again until you can slide the sight into the dovetail far enough.
- Begin to screw the sight pusher a little at a time until your new sight is even on both side of your slide.
- Once adjusted where you want it, get your enclosed Allen wrench and tighten both screws until it is snug (BUT NOT OVER TIGHT).
- If your new sight does not move into the dovetail very easily you may need to add some oil to the dovetail, this might help it move into the dovetail.
- Now that your new sights are in place, put your handgun back together and add some oil to the lubrication points as your manual states and get ready to test fire your handgun.
Before you shoot the handgun
Before you shoot your handgun, you need to make sure that you grip your handgun in the proper manner. A poor grip means in accurate shot placement. Checkout the information below:
Proper Handgun Techniques:
Your hand position on the grip of a handgun is vital to hitting the target. Although the grip configurations of the revolver and the semi-automatic pistol are different, the gripping procedure is the same.
- Right-handed shooter-
- The right hand is the “strong” hand and the left hand is the “support” hand.
- Left-handed shooter-
- The left hand is the “strong” hand and the right hand is the “support” hand.
- Whether you are right or left handed, hold the handgun high on the grip with your strong hand so that the recoil is directed back to the hand and arm in a straight line. This allows better repeat shots and more accurate shooting.
- When shooting a semi-automatic, the rear extension of the frame limits how high your hand can be placed.
- When shooting a revolver, your hand might be able to hold onto the gun quite high.
The goal with your dominant hand is to create a high, firm grip to maximize leverage and control over the pistol.
- High grip: Position the web of your hand as high as possible on the back of the pistol’s grip, just below the slide. This helps reduce muzzle flip.
- Finger placement: Wrap your three lower fingers firmly around the front of the grip. The index finger should remain outside the trigger guard, resting straight along the side of the firearm until you are ready to shoot.
- Pressure: Apply firm pressure from front to back, using the heel of your palm and your lower fingers to squeeze the grip.
The support hand fills the empty space on the grip and provides additional surface contact for stability and recoil management.
- Hand position: Point your support hand forward, then rotate it downward at about a 45-degree angle. This creates a “clamping” effect.
- Fill the gap: Place your support hand firmly against the grip, covering any empty space on the side of the gun. The palm of your support hand should be in contact with the fingers of your dominant hand.
- Thumbs forward: For the “thumbs-forward” technique, both thumbs should be pointing straight toward the target, resting on the side of the pistol frame.
- Begin by gripping the gun with your dominant hand, getting as high as possible on the backstrap.
- Bring your support hand up and fill the gap on the front and side of the grip.
- Place your thumbs forward along the side of the frame, roughly parallel to the barrel.
- Apply inward pressure with both hands: the dominant hand provides front-to-back pressure, while the support hand applies side-to-side pressure.
Good Shooting Techniques
Good shooting techniques to me means minimizing things that will cause you to move the handgun when you pull the trigger.
- Focus on the sights as you shoot
- Place the front post in the rear notch with the top of the post even with the top of the rear notch.
- Then focus on the front sight when you aim.
- Squeeze the trigger.
- Do not jerk the trigger, squeeze the trigger
- There should be no movement of the sights when you pull the trigger.
- Breathing correctly
- I like to take a breath and then exhale very slowly and squeeze the trigger as I exhale.
- All of this takes practice to get it right.
- Focus on the sights as you shoot
Once your grip and trigger technique are solid, start focusing on the sights during live fire – the front sight in particular.
Time For A Test Fire, let’s figure out the correct procedure
Installing new sights is a good thing but you need to get them to where they are hitting what you aim at. So you need to get to a place where you can test fire your gun and see where it is hitting. I like to use a large target with white paper behind it that covers all your previous bullet holes. Because you may not even hit the target with your first shots and this helps you know where the bullets are hitting..
I like to begin at 15 yards with a rifle or handgun, using a table to shoot from, with a stand or rest for support (see photo below), a rest like this works for handguns or rifles and helps to remove most of the other movements so you can see exactly where your handgun is shooting.
Using good shooting technique, you shoot a 3-rounds group and then go see where you shot. If you are hitting on paper or on the target then you keep going. You make an adjustment (see the next section).
So An Adjustment Is Needed
What do you do when an adjustment is needed? An adjustment up or down is called elevation and an adjustment left or right is called windage. The XS Sights – F8 Night Sights adjust easily for windage but elevation is a bit harder.
Adjusting For Elevation:
The F8 sights are not adjustable for elevation, only windage. The only thing you can do is see if you can adjust the height of the front sight.
Adjusting for windage:
When I am at the range and need to make a sight adjustment, I do not completely remove the slide from my handgun. I unload your handgun by removing the magazine and rack the slide until no more bullets are ejected. Open the action and visually look to see if any bullets are present, now you are ready to make a sight adjustment. If a windage adjustment is needed, you move the rear sight in the direction that you need the bullet to go.
- Loosen both securing screws in your rear sight.
- Place the slide into the sight pusher tool. This tool can be used to install and adjust Glock sights, making the interchange of suppressor and RMR-height sights a breeze. When adjusting your rear sight, the sight pusher tool has a scale that allows for precise adjustment. This lets you track how much you’ve moved the sight. Moving the sight left and right will adjust windage only.
Once you are on the target then you can move back to the 25 yard mark and begin again.
Let’s Do Some Final Adjustment
At this point your bullets should be getting close to where you need them to be, so any adjustments made should be very small ones. At this point I like ti shoot 5-shot groups and squeeze that trigger. Then after a couple of 5-shot groups you should be done. Now if after all that work you find out that you do not like the sights themselves then go find the ones that you would rather have and put them on. Take care and enjoy those new sights!
Final Comments
Installing new sights on your handgun is great but you must also spend the time to get your point of aim right. If you follow the steps I talked about, you will have that done and done correctly.
