This is a genuine Glock OEM steel locking block. The locking block locks the barrel into the frame and absorbs slide forces during the firing cycle, making it a core fire-control component.
Features:
Locking blocks are generation-, pin-count-, and frame-size-specific — they are not universal. Match your frame's generation and pin layout (2-pin vs 3-pin) before ordering.
