This locking mechanism is fundamental for safe and reliable operation.
Understanding the Function
The locking block works in conjunction with the barrel’s locking lugs. During firing, the barrel and slide are locked together via the locking block. As the bullet travels through the barrel, the high-pressure gases push the slide backward against the locking block. This locks the slide to the frame, preventing the slide from opening prematurely and allowing the bullet to exit the barrel safely. As the slide recoils, the locking block unlocks the barrel, allowing the slide to complete its cycle.
The Significance of the Locking Block
The locking block’s integrity is directly tied to the safety and reliability of the Glock 19 Gen 3. The locking block absorbs significant forces with each shot. If the locking block fails, the handgun becomes exceedingly dangerous.
