Delta Defence Trigger (Gen4)

The Delta Defence Drop-In System is a full trigger assembly specifically designed for defensive applications where safety and reliability are key. The system is made up of original Glock components that have been modified and enhanced. Break weight ranges from 4.3lb – 4.6lb, reduced from 5.5lb – 6.0lb. All components have been mirror finish polished, allowing for an ultra-smooth action. The Pre-Travel is reduced but maintains enough play to account for high stress in defensive situations. The Reset is short, fast, tactile, and aggressive. This combined with zero Over-Travel is of utmost importance for controlling follow-up shot placement.
