Well, it's not exactly the stuff of legends. It's often mushy, heavy, and can really impact your accuracy. That's where a Kel-Tec SUB-2000 trigger upgrade comes in! In this comprehensive guide, we'll dive deep into everything you need to know about upgrading your SUB-2000's trigger, from the why to the how. We'll explore the benefits, the different upgrade options, and walk you through the installation process. Get ready to transform your SUB-2000 from a decent shooter into a tack-driving machine! Let's get started, shall we?

Why Upgrade Your Kel-Tec SUB-2000 Trigger?

Alright, so why bother with a Kel-Tec SUB-2000 trigger upgrade in the first place? Well, the factory trigger, while functional, leaves a lot to be desired. The primary reason for upgrading is to enhance your shooting experience and improve accuracy. A lighter, crisper trigger pull allows for more precise shot placement. Here's a breakdown of the key benefits:

• Improved Accuracy: A lighter trigger pull reduces the amount of force needed to fire the weapon. This, in turn, minimizes the chance of disturbing your sight picture, resulting in tighter groupings and more accurate shots. A smoother trigger pull also helps eliminate “trigger jerk,” a common issue where shooters inadvertently move the gun as they pull the trigger.
• Enhanced Shooting Experience: Let's face it, a good trigger just feels good. It makes shooting more enjoyable and can significantly boost your confidence. A crisp trigger with a short reset allows for faster follow-up shots, which is crucial in any self-defense scenario or competitive shooting situation.
• Reduced Trigger Pull Weight: The factory trigger on the SUB-2000 can be quite heavy, often exceeding 7 pounds. A lighter trigger pull, typically reduced to around 4-5 pounds or even less, can make a huge difference in your ability to shoot accurately. This is particularly beneficial for shooters with smaller hands or those who find the factory trigger fatiguing after extended shooting sessions.
• Faster Follow-Up Shots: With a shorter reset, you can get back on target faster after each shot. This is critical for rapid target engagement, whether you're at the range or in a more serious situation. A faster reset means less wasted time between shots.
• Increased Confidence: Knowing you have a reliable, responsive trigger can significantly boost your confidence in your shooting abilities. This mental edge can translate into improved performance and a more enjoyable shooting experience. Trusting your equipment is key to good marksmanship.

So, upgrading your Kel-Tec SUB-2000 trigger is more than just a cosmetic change; it's a performance upgrade that can dramatically improve your shooting skills and overall enjoyment of the firearm. Trust me, the difference is night and day!

Trigger Upgrade Options for Your Kel-Tec SUB-2000

Now that you're convinced that a Kel-Tec SUB-2000 trigger upgrade is a good idea, let's explore your options. Several companies offer aftermarket trigger components and complete trigger kits designed specifically for the SUB-2000. Here are the most popular upgrade choices:

• Trigger Spring Kits: This is often the most cost-effective upgrade. These kits typically include a lighter trigger spring and sometimes a lighter hammer spring. Replacing the factory springs can significantly reduce the trigger pull weight and improve the overall feel of the trigger. Installation is usually straightforward and can be done with basic tools.
• Complete Trigger Assemblies: These kits replace the entire trigger assembly, including the trigger, sear, hammer, and springs. They offer a more comprehensive upgrade and can result in a dramatically improved trigger pull. Complete assemblies are generally more expensive but provide the most significant improvement in trigger performance. Be prepared for a slightly more involved installation process.
• Trigger Shoes: While not a direct performance upgrade, a trigger shoe can enhance the feel of the trigger. These are typically wider than the factory trigger, providing a more comfortable and ergonomic surface for your finger. Some trigger shoes also have adjustable pre-travel and over-travel, allowing you to fine-tune the trigger's characteristics.
• Sear and Hammer Upgrades: Some companies offer upgraded sears and hammers that are designed to provide a crisper break and a shorter reset. These components are often made from higher-quality materials and can improve the trigger's longevity and reliability. Installing these components usually requires some disassembly of the trigger assembly.

When choosing an upgrade, consider your budget, skill level, and desired level of improvement. If you're new to gunsmithing, a trigger spring kit might be a good starting point. For those seeking the ultimate trigger upgrade, a complete trigger assembly is the way to go. No matter which option you choose, a Kel-Tec SUB-2000 trigger upgrade will make a noticeable difference in your shooting. Let's explore some of the top brands and products in more detail. Research is key, read reviews, and find something that suits your specific needs and preferences. Look for kits that offer drop-in installation for ease of use.

Popular Kel-Tec SUB-2000 Trigger Upgrade Kits

Okay, let's get down to the nitty-gritty and look at some popular Kel-Tec SUB-2000 trigger upgrade kits and their features. Here are a few well-regarded options available on the market, but always do your own research before making a purchase:

• MCarbo Trigger Spring Kit: MCarbo is a well-known name in the SUB-2000 upgrade world, and their trigger spring kit is a favorite for good reason.

Installation is generally considered very easy, often requiring no more than a few minutes and a couple of basic tools.

Remember to read reviews and watch installation videos before making your purchase. This will help you understand the installation process and ensure the kit is right for you. Make sure you are comfortable with the tools and procedures involved, or seek professional help if needed. Safety first! It is extremely important that the firearm is unloaded during the installation process. Always test your upgraded trigger after installation to ensure proper function and safety. Always check to see what the warranty and return policy is to avoid any unexpected issues.

Installing Your Kel-Tec SUB-2000 Trigger Upgrade

Alright, so you've got your Kel-Tec SUB-2000 trigger upgrade kit. Now, let's talk about the installation process. The exact steps will vary depending on the specific kit you've purchased, but here are the general guidelines. Always refer to the manufacturer's instructions included with your kit. Safety is paramount, so make sure your firearm is unloaded before you begin.

1. Safety First!

• Verify the firearm is unloaded: Remove the magazine and visually and physically inspect the chamber to ensure it is empty. Double-check that no ammunition is present in the firearm or the work area.
• Clear your workspace: Ensure you have a clean and well-lit workspace with plenty of room. This will make it easier to keep track of small parts.
• Gather your tools: You'll likely need a set of punches, a small hammer, a screwdriver, and possibly a bench block. The exact tools will depend on the kit you've purchased. Check the kit's instructions for a detailed list.

2. Disassembly

• Remove the trigger assembly: Consult your kit's instructions or a SUB-2000 disassembly guide. You'll need to remove the trigger assembly from the receiver. This typically involves removing a few pins. Take your time and pay close attention to how the parts fit together. A parts tray or small containers can be helpful to keep track of small parts and screws. Take pictures of the existing parts before you disassemble them, so you can see how to put it back together if you need to.
• Disassemble the trigger assembly: Once the trigger assembly is removed, you'll need to disassemble it. This may involve removing the trigger, sear, hammer, and springs. Again, follow the kit's instructions carefully. Take your time and make sure you understand how each part fits together before you remove it.

3. Installation

• Install the new components: Install the new trigger, sear, hammer, and springs according to the kit's instructions. Ensure all parts are properly aligned and seated. Use the punches and hammer to carefully install any pins.
• Reassemble the trigger assembly: Reassemble the trigger assembly, making sure all parts are in their correct positions. Check for smooth movement of the trigger and other components.

4. Reassembly and Testing

• Reinstall the trigger assembly: Reinstall the trigger assembly back into the receiver.
• Function check: Perform a function check to ensure the trigger is working correctly. This includes dry-firing the firearm (with an empty chamber, of course) and checking the trigger pull weight. Make sure the trigger resets properly and that the safety mechanism is functioning correctly. Cycle the action to ensure the firearm functions properly with the new trigger.
• Test Fire: After all of this, the Kel-Tec SUB-2000 trigger upgrade is complete and you can take it to the range for testing.

If you're not comfortable with any of these steps, consider having a qualified gunsmith perform the installation. Remember to always prioritize safety and follow all instructions carefully. Don't force anything, and take your time. With a little patience, you'll have a much-improved trigger on your SUB-2000 in no time. If you do not feel you have enough experience or tools, consider having a gunsmith install your new parts.

Troubleshooting Common Issues

Sometimes, even with the best instructions, things can go wrong. Here are some common issues you might encounter during your Kel-Tec SUB-2000 trigger upgrade and how to address them.

• Trigger Won't Reset: This is a common issue. Check to make sure that the trigger spring is correctly installed and that the sear is engaging properly with the hammer. Make sure there is nothing preventing the trigger from returning to its forward position. Ensure all pins are properly seated. If the problem persists, you may need to disassemble the trigger assembly and reassemble it, paying close attention to the placement of each component.
• Trigger Pull Too Light: If the trigger pull is excessively light, you might have installed the wrong spring or have a problem with the sear engagement. Double-check the spring specifications and make sure the sear is properly engaging with the hammer. If necessary, consult the manufacturer's instructions or seek professional advice.
• Misfires: Misfires can be caused by a weak hammer spring or improper sear engagement. Make sure the hammer spring is strong enough to reliably ignite the primer. If the sear is not engaging the hammer correctly, the hammer may not strike the firing pin with sufficient force. In either case, re-examine the trigger assembly and replace the parts if necessary.
• Difficulty with Pin Removal: Sometimes, the factory pins can be stubborn to remove. Use a quality punch set and a small hammer. If a pin is proving difficult, try applying some penetrating oil and letting it sit for a while before trying again. Be careful not to damage the receiver or the surrounding parts.
• Parts Not Fitting: Ensure you've purchased a Kel-Tec SUB-2000 trigger upgrade kit that is specifically designed for your model of SUB-2000. If parts aren't fitting correctly, it could be due to a manufacturing defect or an incorrect kit. Contact the manufacturer or retailer for assistance.

If you encounter any persistent problems, it's always best to consult a qualified gunsmith. They can diagnose the issue and provide expert guidance. Safety is always the top priority, so don't hesitate to seek professional help if you're not comfortable working on your firearm. Remember, patience and attention to detail are key to a successful trigger upgrade.
