Description

Trigger Spring Kit — Gen 1–4 & Gen 5-6 Options

Looking for the best way to upgrade your trigger? The M*CARBO Trigger Spring Kit offers two calibrated options to reduce pull weight, smooth the action, and improve reset—far superior to a basic “25¢ trigger job.”

• Reduce average trigger pull from ~5.25 lb to approximately ~3.5 lb. (Average results can vary up to +/- 1 lb)
  • Achieve up to a 33% reduction in trigger pull weight.
• Enhance accuracy and overall pistol performance.
• Easily tune your pistol to an approximate 3.5 lb trigger with this drop-in kit.
• Springs made from high-quality American spring steel for durability and consistent performance.
• Smoother, more refined trigger pull with a straightforward installation.
• Trigger spring designed to offer nearly 30% more power than stock for improved reset and control.
• Owners of Glock 42, 43, and 44: select the Gen 5-6 Trigger Spring Kit option.
• Reduced-power firing pin safety spring minimizes friction to improve trigger feel.
• Improved firing pin springs deliver better consistency and durability over standard springs.
• Swap springs individually to fine-tune primer strike, trigger weight, and reset, or install the full kit for maximum performance.
