Understanding the Importance of Replacement
Common Reasons for Replacement
The Smith & Wesson (S&W) brand has a long and storied history in the world of firearms. From its revolvers to its semi-automatic handguns, S&W is synonymous with reliability, quality, and a commitment to serving both law enforcement and civilian shooters. A critical component of any handgun, including those from S&W, is the rear sight. This unassuming piece of metal or polymer plays a vital role in aiming and achieving accurate shots, and understanding how to maintain and, if necessary, replace your S&W rear sight is an essential skill for any firearm owner. This article will walk you through the process of an S&W rear sight replacement, providing a clear and comprehensive guide to help you improve your handgun’s performance.
The rear sight on your Smith & Wesson handgun is the second point of contact in the aiming process, working in conjunction with the front sight to allow you to accurately target your shots. It’s not merely a decorative element; it’s a crucial functional component. Over time, however, rear sights can become damaged, worn, or simply outdated. Recognizing when a replacement is needed is important for maintaining both accuracy and safe firearm handling.
There are several common reasons why you might need an S&W rear sight replacement. One of the most common is physical damage. Accidents happen, and a hard impact can bend, break, or dislodge the sight. Even without impact, the repeated recoil and handling can cause wear and tear, especially on older models. If the sight is bent, cracked, or the aiming notch is distorted, accuracy will suffer.
Beyond damage, upgrading your rear sight can significantly improve your shooting experience. The standard factory sights on some S&W handguns may not be optimal for your needs. Upgrading to a more visible sight picture, for example, is a popular reason for an S&W rear sight replacement. This might involve opting for sights with a different notch shape, different colors, or even advanced options. Consider options like three-dot sights or sights with a larger notch for quicker target acquisition.
Customization also plays a role. Many shooters choose to replace their factory sights with something more personalized. This might mean choosing a rear sight with tritium inserts for night shooting, a specific color combination, or a style that better suits their preferences. The aftermarket offers a wide range of options for customizing your S&W handgun, allowing you to tailor your setup to your exact needs and preferences.
Identifying the Right Sight Type
Before you start, it’s crucial to know what type of rear sight your S&W handgun uses. This is perhaps the most critical step in the entire process. S&W handguns, like other manufacturers, have used various sight designs over the years. Knowing whether you have a dovetail sight, a Glock-style sight, or another proprietary design is absolutely essential. Trying to install the wrong type of sight will not only be impossible, but it could potentially damage your slide. Identifying your sight type is usually simple. Research your specific model online or consult your owner’s manual to determine the correct type of S&W rear sight you need. Once you have the model number, it makes it easier to get the right fit.
Safety First
Always, always prioritize safety. Before even considering your S&W rear sight replacement, ensure that your firearm is unloaded and the magazine is removed. Visually and physically inspect the chamber to confirm that no ammunition is present. Work in a well-lit, uncluttered space free from distractions. And finally, wear appropriate eye protection throughout the entire process to protect your eyes from any accidental debris or potential injury.
Gathering the Tools and Necessary Supplies
Having the right tools is paramount for any successful DIY gun project, and an S&W rear sight replacement is no different. The correct tools will make the process much easier and reduce the risk of damaging your handgun.
Essential Tools and Materials
First and foremost, you will need a new rear sight compatible with your specific S&W model. Carefully research and purchase the correct replacement. Double-check the manufacturer’s specifications to ensure it fits your handgun. Purchase this before beginning as it is the core requirement.
While not absolutely necessary, a sight pusher tool is highly recommended. These tools, specifically designed for the installation and removal of sights, make the process significantly easier and safer. They provide a controlled and precise way to move the sight without damaging the slide or the sight itself. A quality sight pusher is a worthwhile investment for any gun owner who regularly works on their firearms. The sight pusher is a must-have item.
If you’re not using a sight pusher, you will need a punch and a hammer. A brass or nylon punch is ideal because these materials are softer than steel and will minimize the risk of marring the slide. The size of the punch is important. You will need one that is slightly smaller than the dovetail on the rear sight. Choose a small hammer that provides sufficient force without being excessive.
A bench vise can also be helpful, though it’s optional. If you have a vise, it will help stabilize the slide during the removal and installation process. Use non-marring jaw pads to protect the slide’s finish.
Before the S&W rear sight replacement you might also want to use some lubricants. A lubricant like gun oil or penetrating oil can help ease the process, particularly when dealing with a tight-fitting sight. Apply the lubricant to the dovetail slot on the slide and the base of the new sight.
A small screwdriver may be required if the sight is secured with a set screw. Inspect the new sight to see if it has any screws.
Finally, have cleaning supplies at hand. After the sight replacement, you might want to clean the slide.
Where to Find Supplies
When purchasing your replacement sight, you have several options. Online retailers such as Brownells, MidwayUSA, and other specialty gun supply websites offer a wide selection of sights for S&W handguns. You can often find competitive prices and a vast selection of models. Local gun stores are also a good resource. Staff members can often offer advice and may even have the exact sight you need in stock. You might also consider going directly to the manufacturer’s website. This guarantees you’ll be purchasing a genuine part designed for your specific firearm.
Taking Apart and Reassembling the Handgun
(Note: The following process focuses on the dovetail sight replacement method, as it is the most common type on S&W handguns. Be aware that other sight types might require different procedures. Consult your handgun’s manual if this is not the right approach.)
Removing the Slide (If Necessary)
If the slide has been removed, you can proceed, otherwise remove the slide. Ensure your firearm is unloaded and the magazine is removed, double-checking the chamber.
Removing the Old Sight
Now it’s time for the most crucial part: actually removing the old sight. Remember to work in a safe and well-lit environment.
Using a Sight Pusher
If you have a sight pusher, this is the most straightforward approach. Position the slide securely in the sight pusher, making sure the sight pusher jaws are aligned with the existing sight. The pusher is generally adjustable, allowing you to adapt to the size of the sight. Carefully turn the pusher’s adjustment mechanism, applying even and steady pressure to push the sight out of the dovetail slot. Work slowly and deliberately, making sure the sight moves smoothly. If it seems stuck, apply a small amount of penetrating oil and allow it to sit for a few minutes.
Using a Punch and Hammer
If you don’t have a sight pusher, you will need to use a punch and hammer. Place the slide in a vise, protecting it with non-marring jaw pads. The slide should be oriented so that the dovetail is accessible. Choose a punch that is slightly smaller than the width of the sight. Place the punch on the side of the sight, and gently tap it with the hammer. Apply even pressure, working carefully. Start with light taps and increase the force gradually. Avoid striking the slide itself. Once the sight starts moving, it should become easier to remove.
Preparing for the New Sight
Once the old sight has been removed, clean the dovetail slot thoroughly. Use a brush or a clean cloth to remove any debris or residual lubricant. Then, before you begin your S&W rear sight replacement, it’s helpful to apply a light coat of gun oil or penetrating oil to the dovetail slot and to the base of the new sight. This will help the new sight slide into place more smoothly.
Installing the New Sight
After the dovetail has been cleaned and lubricated, the installation is next.
Using a Sight Pusher
With a sight pusher, carefully align the new sight in the dovetail slot. Make sure the sight is oriented correctly, and it faces the right direction. Use the sight pusher to press the new sight into place, just like you did with the old sight. Ensure the pressure is even and steady.
Using a Punch and Hammer
If you’re using a punch and hammer for the S&W rear sight replacement, the process is similar, but take extra care to avoid damaging the sight or slide. Start with light taps, gradually increasing the force. Be sure you are hitting the correct side. Check your alignment regularly. The punch is used to tap the sight into place, and it might need more force to move the new sight into place.
Securing the Sight
Some rear sights include a set screw to secure them more firmly in place. If your replacement sight has a set screw, carefully tighten it with a small screwdriver after the sight is properly positioned. This adds another layer of security and helps to prevent the sight from moving during recoil.
Putting It All Together
After all this work on your S&W rear sight replacement, reinstall the slide.
Sighting In After the Process
Replacing your rear sight, or replacing any sight for that matter, changes the firearm’s point of impact, and therefore, after installing the new rear sight, it’s essential to sight in your handgun. This is the process of adjusting the sights to ensure that the bullet impacts where you’re aiming.
To sight in your handgun, you’ll want to start at a target at a known distance, usually about 15 yards. Fire a few rounds. If the bullet impacts are consistently high, you will need to adjust the rear sight’s elevation. Most adjustable sights have a mechanism for this. If the bullet impacts are consistently to the left or right, you need to adjust the windage.
Troubleshooting Common Problems
Even with the best preparation, you might encounter some challenges during an S&W rear sight replacement.
If the Sight Is Stuck
If the sight is stuck, do not force it. Excessive force could damage the slide or the sight. Try applying more penetrating oil. Use a sight pusher, or if you are using the punch and hammer method, make sure your punches are seated correctly.
Looseness of the Sight
Sometimes, the new sight might feel too loose after installation. This can affect accuracy. In this case, you might need to try a different sight. Or, if the fit is only slightly loose, you can use a small amount of Loctite or a similar thread-locking compound to help secure it.
Misalignment
Misalignment is a common issue. If the sight isn’t perfectly straight, your shots will be off. You can correct this by carefully using a sight pusher or by tapping the sight gently with a punch and hammer until it’s aligned.
Conclusion
Replacing your rear sight is a manageable task that can improve your shooting experience. By following these steps, you can confidently complete an S&W rear sight replacement and ensure your handgun is performing at its best. Remember that safety is paramount. Take your time, pay attention to detail, and don’t hesitate to seek help if you run into any difficulties. If you’re still feeling uncomfortable, consider taking your handgun to a qualified gunsmith for assistance. Replacing your S&W rear sight can significantly enhance the functionality of your firearm.
Now you have the knowledge and the resources, and you’re ready to upgrade your S&W!
