Ships to all 50 states. Available nationwide.

The Polymer Action Enhancement Kit for Glock® Gen 3 and Gen 4 pistols is a drop-in package built for shooters who demand a cleaner, more consistent trigger pull without complex installation. Designed for the high-dust, dry heat, and suppressor-heavy conditions common in Arizona, this kit combines three precision components to deliver measurable improvements in trigger performance while maintaining factory safety standards.

What’s included in the kit:

• Apex Polymer Action Enhancement Trigger with a Gen 3 trigger bar – centers your finger for a straight, repeatable pull. The trigger bar finish may be either Matte Nickel or Bright Nickel, depending on current production.
• Apex Ultimate Safety Plunger – reduces friction during the trigger cycle for a smoother uptake and reset, even when carbon or dust builds up from extended range sessions.
• Apex Performance Connector – fine-tunes the sear engagement for a crisp, predictable break with less over-travel.

Real-world benefits for your Glock®:

• Reduced trigger pull weight by approximately 1 lb. – Lighter enough to improve shot control during long strings of fire, especially when running a suppressor adds heat and gas blowback.
• Shorter pre-travel, overall travel, and reset distance – Get back on target faster for follow-up shots. The reduced travel also helps prevent trigger drag when debris or sand finds its way into the action.
• Smoother uptake and reset – The polished contact surfaces and redesigned plunger reduce grit and stacking, even after hundreds of rounds in dusty conditions.
• Crisp trigger break – A clean, defined wall with no creep, making it easier to hold the sight picture through the shot.
• Center-mounted pivoting safety – Retains the factory drop-safety geometry so the trigger remains safe for daily carry or duty use.
• Direct drop-in installation – No fitting, filing, or polishing required. Remove your factory trigger assembly and install these parts in minutes. Compatible with Gen 3 and Gen 4 Glock® frames.

Why this kit fits shooters in Arizona:

• Heat and dust accelerate wear on stock trigger components. The Apex Polymer Action Enhancement Trigger uses a durable polymer shoe (with a metal bar) that resists thermal expansion and stays consistent in 110°F+ temps.
• Suppressor use increases carbon fouling inside the frame. The smoother plunger and connector shed carbon more effectively, keeping the reset sharp round after round
