Product Details:

Installation Notes:

This is an internal fire control part that requires basic gunsmithing knowledge for installation. Proper fitting and function testing is essential for safe operation. If you're not comfortable with pistol disassembly and reassembly, we recommend professional installation by a qualified gunsmith.

Why Replace This Part? Over time, springs can lose tension from repeated compression cycles, leading to unreliable trigger reset or disconnector function. Replacing worn springs restores factory-spec performance and ensures your pistol operates safely and reliably.
