Walther Arms 281329710 Threaded Barrel Kit 9mm Luger 4 60 281329710 UPC 723364210570
Product Description
The Walther Arms Factory 9mm Threaded Barrel Kit (MPN: 281329710) is a genuine original equipment manufacturer (OEM) upgrade designed to adapt 4-inch Walther PDP and PPQ M2 9mm handguns for suppressor deployment and muzzle device integration. Featuring a polygonally rifled cold hammer-forged steel barrel with an extended 4.60-inch overall length, this kit includes standard 1/2"x28 tpi right-hand threads to host popular 9mm suppressors, compensators, and muzzle brakes.
Precision-engineered in Ulm, Germany by Carl Walther GmbH, this drop-in conversion kit includes a factory-tuned suppressor-weight recoil spring guide rod assembly and a knurled thread protector. The specialized green-coded recoil spring is optimized to balance slide velocity and ensure reliable cycling when shooting suppressed or unsuppressed across various 9mm grain weights.
Treated with a durable matte black Tenifer finish, the 281329710 barrel delivers maximum resistance against surface wear, thermal stress, and chemical corrosion. Backed by Walther Arms' Legendary Lifetime Limited Warranty, it guarantees factory drop-in fitment, lockup precision, and supreme match-grade accuracy.
Armorer Bench Notes & Real-World Staging Guidance:
Fitment Matrix: Designed specifically for Walther PDP Compact 4", PDP Full Size 4", and PPQ M2 / PPQ M1 4" models chambered in 9mm. (Note: Not compatible with PDP 4.5" or 5" models, PDP Steel Frame models without verifying slide length, PPQ .45 ACP, PPQ .22 LR, or original P99 models without checking locking block generation).
- Perform a complete firearm safety check: drop the magazine, lock the slide rearward, and visually inspect the chamber to verify zero live rounds are present.
- Pull down on the dual frame takedown levers located above the trigger guard while releasing the slide to remove the slide assembly forward off the frame rails.
- Compress and remove the factory recoil spring assembly from the slide cavity.
- Tilt and lift the standard 4-inch factory barrel up and out of the slide housing.
- Drop the Walther 281329710 threaded barrel into the slide housing until seated against the locking block interface.
- Install the included suppressor-weight recoil spring assembly with the guide rod head properly centered on the barrel lug.
- Reassemble the slide assembly onto the frame, perform a dry-fire function test, and check suppressor alignment using a 9mm bore alignment rod before live fire.
