The Heckler & Koch (HK) Law Enforcement Modification (LEM) trigger is a unique and often debated system. Understanding its mechanics and the aftermarket support available, specifically through LEM trigger kits, is crucial for both experienced shooters and those considering upgrading their HK firearm. This guide delves into the intricacies of the HK LEM trigger kit, exploring its benefits, drawbacks, and considerations for installation and usage.
Understanding the HK LEM Trigger
The HK LEM trigger system is designed for a specific feel and operational method, aiming for a blend of safety and speed. It's a double-action-only (DAO) system with a unique characteristic: a pre-travel stage followed by a short, consistent trigger pull. This pre-travel stage helps to ensure a safe and controlled trigger pull, minimizing the chances of accidental discharge.
Key Features of the LEM Trigger:
- Double Action Only (DAO): Each shot requires a full trigger pull, eliminating the need for a separate cocking operation.
- Pre-Travel Stage: This allows for a controlled trigger press before the break, improving accuracy.
- Consistent Trigger Pull Weight: The pull weight remains consistent for every shot, enhancing consistency and reducing shooter fatigue.
- Safety Features: The LEM system incorporates multiple safety features, reducing the likelihood of accidental discharge.
However, the stock LEM trigger isn't universally loved. Many shooters find the factory pull weight too heavy or the pre-travel stage slightly disconcerting. This is where aftermarket HK LEM trigger kits come in.
Benefits of Upgrading with an HK LEM Trigger Kit
Aftermarket LEM trigger kits offer various enhancements over the factory trigger, addressing common complaints and tailoring the firearm's trigger feel to individual preferences. These upgrades can significantly improve shootability and accuracy.
Common Improvements Offered by LEM Trigger Kits:
- Reduced Trigger Pull Weight: Kits often reduce the overall trigger pull weight, resulting in a faster and smoother trigger press.
- Improved Trigger Reset: A crisper reset can speed up follow-up shots.
- Reduced Over-travel: Removing excess trigger movement after the break enhances accuracy and consistency.
- Enhanced Trigger Feel: Many kits provide a more refined and predictable trigger break.
Types of HK LEM Trigger Kits and Considerations
The market offers a variety of HK LEM trigger kits catering to different preferences and budgets. Some focus primarily on reducing pull weight, while others prioritize reducing travel and enhancing the overall feel. Choosing the right kit requires careful consideration of individual needs and shooting style.
Factors to Consider When Choosing a Kit:
- Pull Weight Reduction: How much weight reduction is desired? A drastic reduction might compromise safety for some shooters.
- Material and Construction: The material used in the kit components (e.g., steel, polymer) affects durability and feel.
- Compatibility: Ensure the kit is compatible with your specific HK firearm model.
- Reputation of the Manufacturer: Choose reputable brands with a proven track record of quality and reliability.
- Installation Difficulty: Some kits are easier to install than others; consider your mechanical skills.
Note: Always consult a qualified gunsmith if you are uncomfortable performing the installation yourself. Improper installation can damage your firearm or create safety hazards.
Installing an HK LEM Trigger Kit: A Step-by-Step Overview (General)
While specific steps vary depending on the kit and firearm model, the general process involves:
- Disassembly: Carefully disassemble your firearm, following the manufacturer's instructions and safety precautions. This often involves removing the slide, trigger group, and other components.
- Part Replacement: Replace the old trigger components with the new ones from the kit, ensuring proper alignment and orientation.
- Reassembly: Carefully reassemble the firearm, referencing the manufacturer's instructions.
- Testing and Adjustment: Test the new trigger for proper function and adjust as needed. This might involve fine-tuning the trigger pull weight or over-travel.
