Only when the trigger is fully pulled does the block lower, allowing the hammer to strike the firing pin and fire the cartridge.

Installation Note:

Professional gunsmith installation required. This is a critical safety component that must be properly fitted and function-tested to ensure reliable drop safety protection.
