The Mossberg 590 is a legendary pump-action shotgun, renowned for its reliability and versatility. However, many shooters find the factory trigger to be a bit clunky and heavy. Upgrading the trigger can significantly improve the shooting experience, leading to faster target acquisition and increased accuracy. This guide delves into the world of Mossberg 590 trigger upgrades, covering various options, installation, and considerations.
Why Upgrade Your Mossberg 590 Trigger?
The stock Mossberg 590 trigger is designed for durability and functionality, not necessarily for competition-level performance. Many shooters find the following aspects lacking:
- Heavy Pull Weight: The factory trigger pull can be excessively heavy, leading to fatigue during extended shooting sessions and hindering accuracy.
- Creep: A significant amount of "creep" – the distance the trigger travels before breaking – can lead to inconsistent shot placement.
- Take-up: Similar to creep, excessive take-up before the trigger breaks contributes to imprecise shots.
- Rough Trigger Feel: The factory trigger can feel gritty and imprecise, further impacting shooting performance.
Types of Mossberg 590 Trigger Upgrades
Several upgrade options exist, each offering varying degrees of improvement:
1. Drop-in Trigger Groups:
These are pre-assembled units that replace the entire factory trigger group. They often offer the most significant improvements in pull weight, creep, and overall feel. Popular brands offering drop-in trigger groups include:
- Timney: Known for producing high-quality, precision triggers for various firearms.
- Wilson Combat: A respected name in the firearms industry, offering robust and reliable trigger upgrades.
- Rogers Super Stocks: A popular choice for shooters looking for a substantial upgrade with adjustable features.
Pros: Relatively easy installation, significant performance improvements. Cons: Can be more expensive than individual parts upgrades.
2. Individual Trigger Parts Upgrades:
This approach involves replacing individual components within the factory trigger group, such as the trigger spring and sear. This can provide a more customized upgrade, allowing shooters to fine-tune the trigger pull weight to their preferences. However, it requires more mechanical aptitude and familiarity with firearm disassembly.
Pros: More affordable than complete drop-in units, allows for customization. Cons: Requires more technical skill to install, may not provide the same level of improvement as a complete drop-in group.
3. Polishing and Tuning the Factory Trigger Group:
For those seeking a budget-friendly upgrade, polishing and tuning the factory trigger group can improve the trigger feel. This involves smoothing out rough edges and reducing friction points.
Pros: Cheapest option, relatively simple process. Cons: Requires technical skill, offers the least dramatic improvement compared to other methods.
Installing Your Mossberg 590 Trigger Upgrade
Before undertaking any trigger upgrade, ensure you have a thorough understanding of firearm safety and disassembly procedures. Consult your firearm's manual and watch reputable videos demonstrating the proper disassembly and reassembly process. Improper installation can lead to malfunction and potential injury.
Safety First:
- Always unload your firearm and visually inspect the chamber and magazine to ensure it is completely empty before starting any work.
- Keep your firearm pointed in a safe direction at all times.
- Use proper tools and techniques to avoid damaging any parts.
Each upgrade type will have its own specific installation instructions. Carefully follow the manufacturer's instructions provided with your chosen upgrade.
Choosing the Right Mossberg 590 Trigger Upgrade
The best trigger upgrade for you depends on your budget, mechanical aptitude, and desired level of improvement. Consider the following factors:
- Budget: Drop-in trigger groups are typically more expensive than individual part upgrades or polishing the factory group.
- Skill Level: Individual parts upgrades and polishing require more mechanical skill than installing a drop-in group.
- Desired Performance: The extent of improvement varies based on the chosen upgrade. A drop-in group usually provides the most dramatic improvement.
Conclusion
Upgrading your Mossberg 590 trigger can significantly enhance shooting accuracy and comfort. By carefully considering your needs and following the appropriate installation procedures, you can transform your shotgun's shooting experience. Remember, safety is paramount throughout the entire process. Always prioritize safety and consult reliable sources for guidance.
