This nickel-plated locking block is a direct drop-in for Glock 19, 23, 32, and 38 Gen 3 frames using the 3-pin locking-block layout (2013 and later production). Machined from 17-4 stainless and finished in nickel for corrosion resistance, it restores worn lockup or upgrades a build with a cleaner-looking internal.

Specs:

• 17-4 stainless steel construction
• 44C Rockwell hardness (+/- 2) for durability
• Nickel-plated finish for corrosion resistance
• Fits 3-pin Glock frames (2013 and newer)
• Confirmed fit: Glock 19, 23, 32, 38 — Gen 3

Install: Drift out the locking-block pin, swap the block, and re-seat. Verify your frame is a 3-pin variant before ordering — early Gen 3 frames used a 2-pin block and require a different part. Inspect the trigger-housing pin while the frame is open and replace if it shows wear.
