The Glock FRT (forced reset trigger) is a performance-focused modification designed to change how the trigger resets during the firing cycle, allowing for faster and more consistent follow-up shots.
Unlike traditional Glock trigger upgrades that focus on pull weight or smoothness, an FRT system introduces a mechanical reset interaction—making it one of the most advanced and tunable trigger configurations available.
This guide covers what it is, how it works, and how to properly tune a Glock FRT system for optimal performance.
WHAT IS A GLOCK FRT?
A forced reset trigger (FRT) system uses mechanical interaction between the slide/barrel and internal trigger components to actively reset the trigger during cycling.
Instead of relying entirely on the shooter to release the trigger forward, the system:
- Forces the trigger forward during slide movement
- Resets the trigger automatically
- Allows for faster and more consistent trigger cycles
This results in a forced reset system, rather than a passive reset like a standard Glock trigger.
HOW THE GLOCK FRT WORKS
In a standard Glock:
- The slide cycles rearward
- The trigger resets internally
- The shooter must release the trigger forward to reset
With an FRT system installed:
- The trip component interacts with the slide/barrel during cycling
- A spring-loaded mechanism applies forward pressure
- The trigger is forced forward (reset)
- The shooter can immediately pull again
This creates a faster and more consistent reset cycle while maintaining semi-automatic function.
UNDERSTANDING THE V3 SYSTEM (SPRING-LOADED TRIP DESIGN)
The V3 system introduces a spring-loaded trip, which adds a key layer of tunability.
It uses a modified AR15 bolt catch spring to:
- Apply adjustable tension to the trip
- Control how aggressively the system resets
- Allow tuning based on individual Glock tolerances
This is critical because:
👉 No two Glocks behave exactly the same
👉 Spring tuning directly impacts reliability and feel
POINTED VS ROUNDED TRIP (WHAT’S THE DIFFERENCE?)
Most Glock FRT systems include two trip styles:
Pointed Trip
- More aggressive engagement
- Faster reset interaction
- Increased sensitivity to tuning
- Can feel sharper
Rounded Trip
- Smoother engagement
- More forgiving tuning window
- Better for reliability
- Ideal starting point
👉 Best practice: Start with the rounded trip, then test the pointed version once your setup is dialed in.
TRIGGER SHOE OPTIONS (FLAT VS CURVED)
Different trigger shoes affect control and feel:
Curved Trigger
- Traditional Glock feel
- Familiar and predictable
- Easier transition for most users
Flat Trigger
- More consistent finger placement
- Increased leverage
- Preferred for performance setups
WHY SPRING LENGTH MATTERS (CRITICAL STEP)
Spring tuning is one of the most important parts of the system.
- The spring must be trimmed to the correct length
- Too long → excessive pressure / poor function
- Too short → insufficient reset / failure to function
⚠️ Average working length is around 7.5mm, but this varies by setup.
👉 Always trim coil-by-coil — removing too much will make the spring unusable.
WHY A DEDICATED TRIGGER BAR MATTERS
Using a separate trigger bar for your FRT setup allows you to:
- Avoid modifying your OEM trigger
- Quickly switch between FRT and factory configurations
- Maintain a consistent baseline for tuning
This is especially useful for users running multiple setups or testing configurations.
INSTALLATION & TUNING OVERVIEW
A Glock FRT system is not a drop-in upgrade.
Typical setup includes:
- Installing trigger shoe onto the trigger bar
- Installing and tuning the spring-loaded trip
- Cutting spring to proper length
- Testing engagement and reset behavior
- Adjusting components as needed
Because of tolerance differences, each Glock requires slightly different tuning.
COMMON MISTAKES TO AVOID
- Cutting too much spring at once
- Starting with aggressive (pointed) trip before tuning
- Not testing multiple configurations
- Expecting drop-in performance
- Skipping proper fitment checks
WHO SHOULD USE A GLOCK FRT SYSTEM?
This type of setup is best suited for:
- Users comfortable with mechanical tuning
- Builders looking for maximum trigger performance
- Those wanting adjustable reset characteristics
- Anyone running multiple Glock configurations
FINAL THOUGHTS
The Glock FRT system offers a unique and highly tunable approach to trigger performance.
With the right setup:
- Reset becomes faster and more consistent
- Trigger feel can be customized
- Performance can be optimized for your specific firearm
The key is proper tuning, patience, and incremental adjustments.
