Glock A.R.T. Gen 4 Large Frame Precision Trigger Kit with Mechanical Reset Assistance
The A.R.T. Gen 4 Large Frame is a high-performance, trigger system engineered specifically for Gen 4 large-frame Glock pistols in 10mm and .45 ACP. Using energy from the recoiling slide, the patented A.R.T. system actively drives the trigger forward for an ultra-fast, positive, and audible reset that dramatically outperforms the factory Gen 4 trigger—especially under the heavy recoil of 10mm and .45 ACP.
This kit includes all the premium components our customers expect, now fully optimized for the Gen 4 large-frame platform.
Key Features:
• Upgraded A.R.T. Trigger Assembly (integrated safety shelf for 100% drop-safe reliability)
• Dedicated Gen 4 Large Frame Trigger Housing (precision-machined for perfect fit and long-term durability)
• Three Tempered Steel Reset Levers (precision-ground, low-friction for maximum energy transfer)
• Complete Installation Kit (fine-grit files, polishing pads, and instructions included)
Compatibility: Designed and test-fit exclusively for Gen 4 large-frame Glocks in 10mm and .45 ACP with little to no fitting on the following models:
Full-Size & Long-Slide: • 10mm: G20 Gen4, G40 Gen4 (MOS models included) • .45 ACP: G21 Gen4, G41 Gen4 (MOS models included)
Compact & Subcompact: • 10mm: G29 Gen4 • .45 ACP: G30 Gen4 will require personal fitment and a enhanced recoil assembly (NOT including G30S and G30 Gen4 SF variants)
Extended Compatibility Note: Will NOT fit Gen 3, Gen 5, or Slimline (9mm/.40/.357) models.
Some minor fitting or polishing may be required on New Handgun or when using certain aftermarket slides/barrels. Always test-fire after installation.
Installation Notes: Light filing or polishing of contact surfaces may be needed for optimum reset performance in high-mileage guns. All necessary tools are included—no gunsmith required. Average install time: 30–60 minutes. Step-by-step video guides available on Instagram (@advancedresettech).
