VEX 6 Installation Guide for Gen 6 Glocks


Johnny Glocks VEX 6 Trigger System - Glock Gen 6 Installation Guide

Welcome to your quick-start guide for installing the Johnny Glocks VEX™ 6 Trigger Kit for Glock Gen 6 pistols. This installation involves both frame and slide disassembly, component replacement, and final safety checks.

⚠️ Before you begin: Always ensure your firearm is unloaded and clear. Safety first. Work on a clean surface with adequate lighting.

🛠️ Tools You’ll Need:

  • Glock disassembly tool or punch.
  • Included hex wrench
  • Small flathead or jeweler’s screwdriver (optional but helpful)

STEP 1: VERIFY UNLOADED

Remove magazine, lock slide back, visually and physically inspect chamber, release slide, dry fire in safe direction.

STEP 2: FIELD STRIP

Pull slide slightly rearward, pull down slide lock, remove slide from frame.

STEP 3: FRAME DISASSEMBLY

Remove rear trigger housing pin, locking block, slide stop lever, and trigger assembly.

STEP 4: SLIDE DISASSEMBLY

Remove backplate, striker assembly, depress firing pin safety, remove extractor.

STEP 5: IDENTIFY KIT COMPONENTS

Trigger bar with shoe (do not remove grease), connector, firing pin safety, reduced power safety spring, striker springs, trigger return spring, hex wrench.

STEP 6: FRAME ASSEMBLY

Install connector, trigger bar, slide stop, locking block, and trigger pin.

STEP 7: SLIDE ASSEMBLY

Install firing pin safety and spring (cutout faces inward), install extractor, striker assembly, and backplate.

STEP 8: REASSEMBLY

Join slide and frame, rack slide, dry fire.

STEP 9: STRIKER SPRING SELECTION

  • Defensive: 5 lb (yellow) or 4.5 lb (orange)
    • 4.5 & 5 both are 100% primer strike reliable.
    • The 4.5 lb spring break weight averages 3.5-4.25
    • The 5 lb spring, break weight averages 4-4.75
    • Install the appropriate spring for your level of comfort
  • Competition: 4.5 lb (orange) or 4 lb (green)
    • Please note if you are using harder primers the 4 lb spring is susceptible to light strikes.
    • 4.5 lb break weight averages 3-2.25
    • 4 lb break weight averages 2.5-2

STEP 10: SAFETY CHECKS

Trigger safety, drop safety, firing pin safety must all pass.

*OPTIONAL ADVANCED SETUP

Trigger return spring upgrade and overtravel screw adjustment.

FINAL NOTES

No break-in required. Test thoroughly before live fire.

Critical Notes (Read This)

  • Do not wipe off the grease on the trigger bar/shoe — it’s there for a reason.
  • Work on a flat surface with room — small parts can launch.

  • If you adjust/tune and anything feels off, return to baseline and contact support or a qualified armorer.

Troubleshooting & Common Issues

If something doesn’t feel right after installation, don’t force it. Most issues come from seating, alignment, or tuning being pushed a little too far. Use the guidance below to identify what to check.

Trigger Does Not Break

What it usually means

  • The system is over-adjusted or not returning to its proper starting position.

What to check

  • Return to the baseline configuration shown in the video.
  • Remove any optional tuning changes and confirm proper function before reintroducing adjustments.

No Reset or Weak Reset

What it usually means

  • A spring interaction or adjustment is preventing full forward travel.

What to check

  • Confirm the system is assembled in its baseline configuration.
  • Verify components are seated correctly and moving freely.
  • Re-test reset before making any further changes.

Inconsistent or “Spongy” Feel

What it usually means

  • You’re feeling normal striker movement amplified by tuning choices.

What to check

  • Try the baseline spring setup first.
  • Remember: striker-fired systems will always have some movement—tuning is about feel, not eliminating motion entirely.

Trigger Safety Does Not Engage Properly

What it usually means

  • Something is interfering with the trigger’s forward position.

What to check

  • Confirm nothing is preventing the trigger shoe from returning fully forward.

  • Re-run the trigger safety check shown in the video before proceeding.

Fails Safety Validation Checks

What it usually means

  • A component is not seated correctly or the system has been over-tuned.

What to do

  • Stop.
  • Return the system to the baseline setup.
  • Re-verify all safety checks exactly as demonstrated in the video before use.


Overtravel / Adjustment Issues

What it usually means

  • Too much adjustment was removed from the system.

What to check

  • If adjustment creates unreliable function, remove the adjustment from the equation and confirm the system functions correctly without it.
  • Reliability always comes before feel.

General Rule

If you make a change and something feels off:

  1. Go back to baseline
  2. Confirm safe function
  3. Then re-introduce changes one at a time

If you’re unsure at any point, stop and reach out.
