Advance Tips: How To Adjust Glock 19 Rear Sight?

If you’re a Glock 19 owner, you know that the rear sight is one of the key components to accuracy. After all, it’s the last thing your eye sees before the bullet leaves the barrel. So, if it’s not properly aligned, your shots will be off target. Fortunately, adjusting the rear sight is a relatively easy process that only requires a few tools and a little bit of know-how.
First, you’ll need a small flathead screwdriver, a punch or small nail, and a hammer. You’ll also need a clean, well-lit work area where you can lay out your Glock 19 and all of your tools.
Once you have everything gathered, begin by removing the magazine and clearing the chamber. Next, take a look at the rear sight. You’ll notice that there are two small Allen screws on either side of the sight. These screws are what you’ll use to adjust the sight.
Using your punch or small nail, tap out the left-hand screw. Be careful not to lose the screw, as it’s easy to misplace in a well-lit room. With the left-hand screw removed, you can now use your flathead screwdriver to adjust the rear sight.
Turn the screwdriver clockwise to move the sight to the right, and counterclockwise to move it to the left. Once you’ve made your adjustments, replace the left-hand screw and tighten it down.
Now it’s time to move to the other side. Again, use your punch or small nail to tap out the right-hand screw. With the screw removed, you can once again use your flathead screwdriver to make adjustments. Remember, turn the screwdriver clockwise to move the sight to the right, and counterclockwise to move it to the left.
Once you’re satisfied with the position of the rear sight, replace the right-hand screw and tighten it down. That’s it! You’ve now successfully adjusted the rear sight on your Glock 19.
