What the Glock Locking Block Actually Does
The locking block is a critical structural component in the Glock design:
Provides a hardened steel bearing surface where the barrel’s locking lug cams in and out during the firing cycle
Helps manage recoil forces, distributing stress from the slide and barrel into the frame NDZ Performance+1
Ensures correct barrel lockup and unlock timing, which is essential for accuracy and reliable extraction/ejection
Works hand-in-hand with the slide, barrel, and frame rails to keep the pistol in safe, consistent alignment
When a locking block is worn, out-of-spec, or incorrectly matched to the frame generation, shot-to-shot reliability and long-term durability can both suffer. A correct OEM-style block restores factory geometry and support. Midwest Gun Works+1
