Understanding Your Glock’s Aiming System
The Basics of Glock Sights
The reliability and simplicity of Glock pistols have made them a favorite choice for both professional and recreational shooters worldwide. However, even the most accurate firearm requires proper sighting to achieve its full potential. Factory sights, while functional, often leave room for improvement in terms of accuracy and visibility. This guide provides a thorough explanation of how to adjust Glock sights for optimal performance. We’ll explore the different types of sights available, the necessary tools, and step-by-step instructions for making adjustments, all while emphasizing the crucial role of safety.
Factory vs. Aftermarket
Standard Glock pistols come equipped with what are considered basic sights. The front sight is typically a post, and the rear sight is a U-shaped notch. These sights, though durable and practical for quick target acquisition, can sometimes lack the precision needed for advanced shooting techniques or longer-range engagements. The trade-off often lies in the compromise between cost-effectiveness and maximum accuracy. For many shooters, these factory sights suffice, especially for defensive purposes.
The market offers a wide range of aftermarket sight options designed to enhance accuracy, target acquisition speed, and overall shooting experience. These upgrades can be particularly beneficial for competitive shooting, hunting, or self-defense scenarios where precision is paramount. Some popular brands in the aftermarket sight space offer sights specifically designed for Glock pistol platforms.
Elevation vs. Windage
One of the most crucial distinctions to understand is the difference between elevation and windage. Elevation refers to the vertical adjustment of the sights. It affects where your shots land vertically – whether too high or too low. Windage, on the other hand, controls the horizontal adjustment. It determines whether your shots are hitting to the left or right of your intended target. Accurately adjusting both elevation and windage is critical for achieving precise shots. Think of these two as the x and y coordinates of your bullet’s trajectory.
Essential Gear and Tools
Having the right tools is crucial for any successful sight adjustment project. The following items are vital for working on your Glock pistol’s sighting system safely and effectively:
Sight Pusher Tool
This specialized tool is indispensable. It allows you to carefully and precisely move the rear sight laterally, making windage adjustments. There are sight pushers specifically designed for Glocks, and there are universal models that can accommodate a variety of pistols. The best option depends on your budget and the likelihood of future use.
Punch and Hammer
While a sight pusher tool is ideal, a brass punch and a hammer can also be used to move the sights. This method requires more care and a steady hand to prevent damage to the slide or sights. A brass punch is preferable to a steel punch, as it’s less likely to mar the finish.
Screwdrivers
If you opt for adjustable sights, you’ll almost certainly need screwdrivers. Make sure you have the correct size and type to fit the adjustment screws on your chosen sight system.
Torque Wrench
Certain aftermarket sights, especially those with adjustable elements, may require a torque wrench to tighten screws to the manufacturer’s specifications. This is critical for ensuring proper function and preventing the sights from loosening during use.
Eye Protection
Safety glasses are non-negotiable. You’ll be working with metal, and there’s always the risk of debris flying into your eyes.
Gun Vise or Bench Rest
While optional, a gun vise or bench rest can greatly improve stability and accuracy while making adjustments.
Cleaning Supplies
Cleanliness is next to godliness, especially when dealing with firearms. Having cleaning solvents and cloths on hand will allow you to keep the sights and slide free from debris.
Prioritizing Safety: The Cardinal Rule
Safety is paramount when handling any firearm. Before beginning any sight adjustment, adhere to these critical safety protocols:
Unloaded Firearm
Ensure the firearm is unloaded: Always confirm that the firearm is unloaded by visually inspecting the chamber and manually cycling the slide.
Follow Manufacturer’s Instructions
Follow manufacturer’s guidelines: Always read and understand the manufacturer’s safety instructions before working on your Glock pistol.
Safe Direction
Point in a safe direction: Always point the muzzle in a safe direction, even when working with the firearm. A safe direction is where an accidental discharge would cause no harm.
Wear Eye Protection
Wear eye protection: As mentioned, eye protection is essential to protect your eyes from any flying debris.
Handle Components With Care
Handle components with care: Treat all firearm components with respect and care. Avoid dropping parts or applying excessive force.
Preparing Your Pistol for Adjustment
Before you start making adjustments, you need to prepare your Glock pistol. This might involve disassembly and cleaning.
Field Stripping
Field stripping the Glock pistol to separate the slide from the frame is often necessary to work on the sights. The basic steps include:
* Ensure the pistol is unloaded.
* Pull down the takedown levers on both sides.
* Pull the slide back slightly.
* Push the slide forward and off the frame.
* Remove the barrel and recoil spring assembly.
While performing the actual sight adjustment, keep the slide securely in place, either in a vise or resting on a stable surface.
Cleaning
Cleaning: Before beginning, use a solvent to clean the slide and sights, and use a clean cloth to wipe them down.
Adjusting Factory Sights – If Applicable
Factory sights often come with limited adjustability, but knowing the basics is worthwhile.
Windage Adjustment
The standard method for making windage adjustments with factory sights is to use a sight pusher tool or, with care, a punch and hammer. The direction you move the rear sight correlates directly to the point of impact. If your shots are hitting left, you need to move the rear sight to the right to bring the point of impact to the center. Small adjustments are preferable, and after each adjustment, you should test fire.
Elevation Adjustment
Factory sights generally lack elevation adjustment capabilities. If you find yourself shooting consistently high or low, you will likely need to replace the front or rear sight with one of a different height to correct the issue.
Adjusting Aftermarket Sights: A Guide by Type
The world of aftermarket sights is vast. Here’s how to approach adjustments based on the sight type.
Fixed Sights
These sights, similar to factory sights, require a sight pusher tool or a punch and hammer.
Adjustable Sights
Windage
Adjustable sights generally have a small screw or mechanism that allows you to move the rear sight laterally. Rotate the screw in the direction indicated by the sight manufacturer’s instructions. This will control how your shots hit left or right. Always make small adjustments, fire a group of shots, and evaluate the results before making further changes.
Elevation
Adjustable sights often have a similar adjustment screw or system for elevation. Rotate the screw to raise or lower the rear sight, thereby affecting where your shots hit vertically. Again, small adjustments, testing, and careful observation are the key to successful elevation adjustments.
Fiber Optic and Tritium Sights
These sights provide excellent visibility, but they don’t always have built-in adjustability beyond what is possible with a sight pusher tool. For these types of sights, the main focus is ensuring they are properly installed and zeroed at your preferred range. Regular cleaning and inspection are crucial.
Achieving the Perfect Zero
Zeroing your Glock pistol is the process of adjusting the sights so your shots consistently hit the target at your desired distance. Here is the process:
Selecting Distance
Determine the target distance you want to use. Common distances include 15 yards and 25 yards.
Shooting a Group
Take a few shots at the target. The key is to group your shots together.
Analyzing Impact
Evaluate where the group of shots impacted the target in relation to your point of aim.
Adjusting Sights
Based on your group’s location, adjust the sights accordingly. For example, if your shots are hitting left, move the rear sight to the right.
Repeating the Process
Repeat the process of shooting, analyzing, and adjusting until your shots consistently hit the target at your chosen zeroing distance.
Troubleshooting Potential Problems
You might encounter some issues during the sight adjustment process. Be prepared with some solutions:
Difficulty Moving Sights
If the sights are difficult to move, make sure you are using the correct tools and applying force in the proper direction. Lubricating the slide might help.
Inaccurate After Adjustment
If you still get inaccurate shots, double-check your adjustments. You may need to further refine your adjustments and/or practice your shooting technique.
Damaged Sights
Always use the correct tools and follow all manufacturer’s instructions to avoid damaging your Glock sights.
Other Common Issues
