The Heckler & Koch (HK) LEM (Law Enforcement Modification) trigger is renowned for its unique and highly effective trigger mechanism. This guide delves into HK LEM trigger kits, exploring their features, benefits, and considerations for those looking to upgrade or customize their HK firearms. We'll cover everything from understanding the LEM system to choosing the right kit and installation best practices.
Understanding the HK LEM Trigger System
Before diving into aftermarket LEM trigger kits, it's crucial to understand the factory HK LEM system. The LEM trigger differs significantly from traditional double-action/single-action (DA/SA) or single-action (SA) triggers. Its defining characteristic is the consistent, relatively long trigger pull, regardless of whether the firearm is cocked or not. This consistent trigger pull is often cited as a key advantage for law enforcement and self-defense applications, promoting faster and more reliable shot placement under stress. The system uses a pre-cocked striker, eliminating the need for a separate hammer cocking process.
Key Features of the Factory LEM Trigger:
- Consistent Trigger Pull: This is arguably the most significant feature of the LEM system, offering predictability in various situations.
- Pre-cocked Striker: The striker is always ready, simplifying the shooting process.
- No Manual Safety: The LEM system inherently relies on a trigger safety mechanism rather than a separate manual safety lever.
- Reduced Trigger Travel: Compared to traditional DA/SA systems, the LEM system generally features less trigger travel.
Why Upgrade with an HK LEM Trigger Kit?
While the factory LEM trigger is effective, some shooters seek further customization to fine-tune the trigger pull, reduce overtravel, or improve the overall feel. Aftermarket LEM trigger kits offer several advantages:
- Reduced Trigger Pull Weight: Some kits allow for a lighter trigger pull weight, potentially enhancing speed and accuracy.
- Improved Trigger Reset: Certain kits can improve the tactile feel of the reset, making it easier to feel when the trigger is ready to fire again.
- Enhanced Trigger Break: A crisper, cleaner break can improve shot precision.
- Reduced Overtravel: Reducing overtravel shortens the distance the trigger travels after the shot, leading to quicker follow-up shots.
Choosing the Right HK LEM Trigger Kit: Factors to Consider
Selecting the optimal HK LEM trigger kit requires careful consideration of several factors:
- Specific Firearm Model: Ensure the kit is explicitly compatible with your particular HK firearm model.
- Desired Trigger Pull Weight: Determine your preferred trigger pull weight – lighter isn't always better; too light can compromise safety.
- Budget: HK LEM trigger kits vary in price depending on the manufacturer and features included.
- Reputation of the Manufacturer: Choose a reputable manufacturer with a proven track record of producing high-quality, reliable parts.
Installation of an HK LEM Trigger Kit
Installing an HK LEM trigger kit typically requires specialized tools and expertise. Improper installation can render your firearm unsafe and should be avoided. If you lack the necessary experience, consider having a qualified gunsmith perform the installation. Always consult the manufacturer's instructions provided with the kit. Safety should always be the top priority.
