Drops into Glock 22 Gen 3 and Gen 4 full-size frames with no fitting and no slide work. Direct OEM-spec replacement for the factory .40 S&W barrel — keep the slide and frame, swap the barrel.

Machined from 416R stainless steel and finished in salt-bath black nitride for a hard, corrosion-resistant wear surface that holds up to suppressed and high-round-count use. Factory contour, factory chamber, factory locking lug geometry — no headspace work and no slide-to-barrel fitment.

Features:

• .40 S&W chambering, factory-spec dimensions
• 4.49-inch length matches OEM Glock 22 barrel
• 416R stainless construction with salt-bath black nitride finish
• Right-hand twist conventional rifling
• Drop-in fit on Glock 22 Gen 3 and Gen 4 frames
• No fitting and no headspace work required

Run 100–150 rounds for break-in before relying on the barrel for carry. Confirm the slide and recoil spring assembly are within factory spec — worn slides or non-OEM recoil setups can affect lockup and may require additional fitment.
