Let's get started!

The Benefits of a Kel-Tec SUB-2000 Trigger Upgrade: Why Bother?

So, why bother with a Kel-Tec SUB-2000 trigger upgrade in the first place? Well, the factory trigger on the SUB-2000, while functional, often leaves something to be desired. It can feel a bit gritty, have a long pull, and a somewhat heavy weight. Upgrading the trigger addresses these issues head-on, offering a range of benefits that translate directly to a better shooting experience. Firstly, a smoother trigger pull is a game-changer. It allows for more consistent and precise shot placement. You'll find that your groups tighten up, and you'll experience fewer fliers. A crisp, clean break – the point where the trigger releases the firing pin – is crucial for accuracy. Upgraded triggers provide precisely that, eliminating the vagueness and unpredictability of the factory trigger. Secondly, reducing the trigger pull weight can significantly improve your shooting. A lighter pull makes it easier to maintain control, especially during rapid fire. This means less fatigue and more accurate follow-up shots. A lighter trigger also reduces the chance of unintentionally jerking the trigger, which can throw off your aim. Moreover, many aftermarket trigger upgrades also feature a shorter reset. This means the trigger resets faster after each shot, allowing for quicker follow-up shots. This is a huge advantage in dynamic shooting scenarios or when you need to engage multiple targets quickly. Finally, a Kel-Tec SUB-2000 trigger upgrade can simply make shooting more enjoyable. A better trigger makes the whole experience feel more refined and responsive, increasing your overall satisfaction with your firearm. The difference is night and day; the improvement in feel is truly remarkable. Ultimately, a trigger upgrade is a worthwhile investment for any SUB-2000 owner looking to enhance their carbine's performance and enjoy a more satisfying shooting experience. Whether you're a competitive shooter or a recreational plinker, the benefits are undeniable. The transformation from the factory trigger to an upgraded one is a noticeable improvement, making the SUB-2000 even more fun to shoot. The improved trigger pull, combined with a shorter reset and reduced weight, leads to greater accuracy, better control, and faster follow-up shots. Trust me, guys, it's worth it.

Exploring SUB-2000 Trigger Upgrade Options

Alright, let's talk options. There are a few different paths you can take when it comes to a Kel-Tec SUB-2000 trigger upgrade. The good news is, there's likely an upgrade that fits your needs and budget. The most common upgrades involve replacing or modifying key trigger components. One popular upgrade involves replacing the entire trigger unit. This usually includes a new trigger, sear, and sometimes other internal components. These complete trigger assemblies are often designed for a lighter, smoother pull and a shorter reset. Another option is to upgrade individual parts. This could involve replacing the trigger spring, sear, or hammer spring. These upgrades can often be done more affordably and can still provide a significant improvement in trigger feel. Some companies offer trigger kits that include a selection of springs and other small parts designed to optimize trigger performance. Then, there's trigger polishing. This involves polishing the contact surfaces of the trigger components to reduce friction and improve smoothness. This can be done with a polishing compound and a bit of elbow grease, or you can send your parts to a gunsmith for a professional polishing job. Additionally, some companies offer drop-in trigger upgrades. These are designed to be easily installed without any gunsmithing knowledge. You simply remove the factory trigger components and drop in the new ones. These are great for those who want a quick and easy upgrade. The type of upgrade that's best for you will depend on your budget, your gunsmithing skills, and your desired level of performance. Consider your shooting style, how you plan to use your SUB-2000, and your comfort level with gun modifications when making your decision. Researching different brands and models and reading reviews can also help you choose the right upgrade. Ultimately, the goal is to find an upgrade that gives you the best trigger feel and improves your shooting accuracy.

Step-by-Step: Installing Your SUB-2000 Trigger Upgrade

Alright, let's get down to business and talk about how to install a Kel-Tec SUB-2000 trigger upgrade. Installing a trigger upgrade is a relatively straightforward process, even for those with limited gunsmithing experience. However, it's crucial to follow the instructions carefully and take your time to avoid any mistakes. Before you start, make sure you have the following things ready. First, you'll need your SUB-2000 and your new trigger upgrade kit. Ensure you have the right tools, including a set of gunsmithing punches (especially a roll pin punch), a small hammer, and a set of Allen wrenches. It's also a good idea to have a workspace that is well-lit and organized, with a clean surface to work on. Safety glasses are a must! It's always best practice to double-check that your firearm is unloaded. Remove the magazine and visually inspect the chamber to ensure the gun is clear. Now, let's get started. First, disassemble the SUB-2000. This typically involves removing the handguard, the receiver pins, and the trigger group. Refer to your SUB-2000 owner's manual for specific instructions on how to disassemble your firearm. With the trigger group removed, you can begin replacing the factory components with your new upgraded parts. The exact steps will vary depending on the upgrade kit, so carefully follow the manufacturer's instructions. Usually, you'll need to remove pins, replace springs, and install new trigger components. Use your punches and hammer to carefully remove and install pins, and take extra care not to damage any of the parts. Make sure to lubricate the new parts as instructed in the kit, using a quality gun oil or grease. Once all the new components are installed, reassemble the trigger group and reinstall it into the receiver. Again, follow the manufacturer's instructions to ensure proper assembly. After you've reassembled the SUB-2000, perform a function check. Dry-fire the gun several times, and make sure the trigger functions smoothly and the firing pin drops properly. Check for any malfunctions or unusual sounds. It's always a good idea to test-fire the gun at a range to ensure everything is working correctly and to confirm your accuracy. If you encounter any problems, don't hesitate to consult the manufacturer's instructions or seek professional assistance from a gunsmith. Remember, a proper installation is key to ensuring the safety and reliability of your firearm. Take your time, follow the instructions carefully, and double-check your work. If you're not comfortable with any step of the process, it's always best to have a qualified gunsmith perform the installation. With a bit of patience and attention to detail, you'll have your SUB-2000 upgraded and ready to go in no time. The feeling of that crisp, clean trigger pull will be well worth the effort!

Troubleshooting Common SUB-2000 Trigger Upgrade Issues

Sometimes, even with the best of intentions, things don't go exactly as planned. Let's talk about some common issues that can arise during a Kel-Tec SUB-2000 trigger upgrade and how to troubleshoot them. One common issue is a gritty or rough trigger pull even after the upgrade. This can be caused by a few things: improper lubrication, burrs on the new components, or a misaligned trigger. Make sure you've properly lubricated all the moving parts with a quality gun oil or grease. Inspect the new components for any burrs or imperfections and remove them with a file or polishing compound if necessary. If the trigger is still gritty, carefully check the alignment of the trigger and sear. Another problem is a failure to fire. This can occur if the firing pin isn't striking the primer hard enough. This can be caused by a weak hammer spring, a misaligned firing pin, or a binding trigger. Ensure the hammer spring is properly installed and that the trigger is fully releasing the hammer. Check the firing pin for any damage or obstructions and clean the firing pin channel. Also, a trigger that doesn't reset can be frustrating. This can be caused by a weak trigger spring, a binding sear, or an improperly installed trigger. Make sure the trigger spring is correctly installed, and the sear is clean and lubricated. Check the trigger components for any damage or obstruction and ensure they are moving freely. If the trigger feels too light or unsafe, this might be due to an overly light trigger spring or improper sear engagement. Make sure you use the correct trigger spring and that the sear properly engages the hammer. Double-check all the components to ensure they are correctly installed and functioning as intended. If you are experiencing malfunctions or unusual behavior, it's best to disassemble the trigger group and re-examine all the components. Refer to the manufacturer's instructions and seek assistance from a gunsmith if needed. Proper troubleshooting is a combination of patience, attention to detail, and a little bit of gun knowledge. Don't get discouraged! Often, the solution is something simple, such as a minor adjustment or a little bit of extra lubrication. Always prioritize safety, and if you're not comfortable troubleshooting the issue yourself, seek professional help. Remember, a properly functioning trigger is essential for the safe and reliable operation of your SUB-2000. It is important to remember safety first when dealing with firearms.

Maintaining Your Upgraded Trigger

Once you've successfully upgraded your Kel-Tec SUB-2000 trigger, proper maintenance is key to keeping it running smoothly and reliably. The good news is, maintaining an upgraded trigger isn't complicated and doesn't require a lot of time. Regular cleaning and lubrication are essential. After each shooting session, or at least every few hundred rounds, disassemble the trigger group and clean the components with a suitable solvent. Remove any dirt, carbon buildup, or debris that could affect the trigger's performance. Once the parts are clean, apply a quality gun oil or grease to all the moving parts. This helps reduce friction, prevent wear, and ensure a smooth trigger pull. Over time, trigger springs can wear out. Regularly inspect the trigger spring and other springs for any signs of wear, such as fatigue or breakage. Replace worn springs to maintain optimal trigger function. Inspect the trigger components for any damage or wear. Look for any burrs, rough spots, or other imperfections. If you find any, you may be able to smooth them out with a file or polishing compound. Otherwise, you may need to replace the damaged parts. Check the screws and pins for tightness. Over time, these can loosen due to vibration. Make sure all screws and pins are securely in place to prevent any malfunctions. Pay attention to any changes in trigger feel. If you notice the trigger becoming gritty, heavier, or less responsive, it could be a sign of a problem. Take the time to troubleshoot the issue and address it promptly. With regular maintenance, your upgraded trigger will provide years of reliable service and a consistently enjoyable shooting experience. Preventive maintenance is always better than reactive repairs. Make it a habit to clean and lubricate your trigger after each use, and inspect the components regularly. By following these simple steps, you can keep your trigger running smoothly and ensure that your SUB-2000 is always ready to perform. Your attention to detail will ensure optimal performance and extend the life of your trigger upgrade.
