Mastering the Shotgun Trigger: A Guide to 870 Trigger Upgrades & Pull Weight Reduction
As a seasoned hunter, competitive shooter, and outdoor enthusiast for over a decade, I’ve spent countless hours behind the trigger of various shotguns. One of the most impactful upgrades you can make to almost any shotgun – especially popular models like the Remington 870 and Benelli Nova – is addressing the trigger. A smoother, lighter trigger pull can dramatically improve accuracy, reduce flinch, and ultimately enhance your shooting experience. This guide will delve into everything you need to know about 870 trigger upgrades, how to lighten a shotgun trigger pull, understanding trigger pull weight, and diagnosing common issues like trigger creep and trigger slap. We’ll cover everything from basic adjustments to full trigger replacements, helping you find the best solution for your needs.
Understanding Trigger Mechanics & Terminology
Before diving into upgrades, let’s establish a common understanding of shotgun trigger mechanics. The trigger pull weight refers to the amount of force, measured in pounds of pressure to pull a trigger, required to release the firing pin. The average trigger pull weight for many factory shotguns falls between 5-8 pounds, which can feel heavy and mushy. A lightest trigger pull isn’t always best; a balance between safety and performance is crucial.
What is Trigger Creep?
Trigger creep is that frustrating sensation where the trigger doesn't immediately release when you start applying pressure. Instead, it moves backward gradually, creating uncertainty and potentially throwing off your shot. This is often caused by worn parts, improper adjustment, or simply a lower-quality factory trigger.
What is Trigger Slap?
Trigger slap occurs when the trigger moves excessively before the hammer releases. It’s often more noticeable and can be a sign of significant wear or a poorly fitted trigger. Both creep and slap negatively impact accuracy and consistency.
Measuring Trigger Pull Weight
Accurately knowing your current trigger pull weight is the first step. You’ll need a trigger weight scale, available from most shooting sports retailers. These scales typically measure in ounces or pounds. Follow the scale’s instructions carefully for accurate readings. Taking multiple readings and averaging them is recommended. You can find helpful demonstrations on how to use these scales on sites like MidwayUSA's Expert Advice.
Shotgun Trigger Upgrade Options
There are several paths you can take to improve your shotgun’s trigger. The best option depends on your budget, skill level, and desired outcome.
Factory Trigger Adjustments (Limited Scope)
Some shotguns, particularly older models, allow for limited adjustments to the trigger pull weight. This usually involves adjusting a screw or spring within the trigger group. However, be extremely cautious when attempting this. Improper adjustment can lead to malfunctions or unsafe conditions. Always consult the owner’s manual and proceed with extreme care. This is generally not a viable option for modern shotguns.
Drop-In Trigger Systems
Drop-in trigger systems, like those offered by Timney Triggers, are a popular and relatively easy upgrade. These systems replace the entire factory trigger group with a pre-assembled unit. They typically offer a significantly lighter and smoother trigger pull. Learning how to adjust a Timney trigger is straightforward, and they often require minimal gunsmithing experience. These are readily available for the Remington 870 and other common models.
Complete Trigger Group Replacements
For more advanced shooters or those seeking maximum performance, a complete trigger group replacement is the way to go. This involves disassembling the factory trigger group and replacing each component with aftermarket parts. This requires more skill and patience but allows for a highly customized trigger pull.
Specific Models: 870 & Benelli Nova
Let’s look at specific upgrade options for two popular shotguns.
Remington 870 Trigger Upgrade
The Remington 870 trigger upgrade market is vast. Popular options include:
- Timney Triggers: Known for their clean break and adjustable pull weight.
- CMC Triggers: Another excellent option offering a crisp, consistent pull.
- TriggerHappy: Offers a variety of trigger components for customization.
The 870’s trigger group is relatively accessible, making upgrades manageable for experienced DIYers. However, always prioritize safety and follow instructions carefully.
Benelli Nova Trigger Upgrade
The Benelli Nova trigger upgrade options are more limited than the 870, but still available. While drop-in options are less common, you can find aftermarket trigger springs and components to reduce pull weight. Due to the Nova’s more complex trigger mechanism, professional installation is often recommended.
Understanding Trigger Pull Weights & Applications
What’s a good trigger pull weight? It depends on the intended use. Here’s a general guideline:
| Application | Recommended Pull Weight |
|---|---|
| Hunting | 3-5 pounds |
| Sporting Clays/Skeet | 2-4 pounds |
| Competition (IPSC, 3-Gun) | 1.5-3 pounds |
| Home Defense | 4-6 pounds (Safety is paramount) |
For concealed carry applications, a slightly heavier trigger pull (around 5-7 pounds) is often preferred for safety reasons. The best trigger pull weight is the one that allows you to consistently and accurately engage your target without inducing flinch.
The Three-Trigger Shotgun: A Historical Note
You may encounter references to a three trigger shotgun or a double barrel shotgun trigger. These are typically older designs, like the Stevens three trigger shotgun, where each barrel has its own trigger, and a third trigger engages both barrels simultaneously. These systems are quite different from modern single-trigger shotguns and require specialized knowledge for repair or modification.
Safety First: Important Considerations
Modifying a firearm is a serious undertaking. Always prioritize safety:
- Unload the firearm completely before beginning any work.
- Wear safety glasses to protect your eyes.
- Consult a qualified gunsmith if you are unsure about any step.
- Always test the firearm with dummy rounds before using live ammunition.
- Familiarize yourself with all applicable laws and regulations regarding firearm modifications in your state. The Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) website is a valuable resource.
