Threaded 9mm replacement barrel for the Glock 17 Gen 1, Gen 2, and Gen 3 — drop-in fit, no slide work or hand-fitting required. 416R stainless steel, the same alloy used for match-grade rifle barrels, button-rifled with a 1:16 twist to stabilize 115- through 147-grain 9mm Luger loads. Finish is left in the white for shooters who want to refinish, Cerakote, or run the bright contrast under a dark slide.
The 1/2x28 muzzle thread is the standard pitch for 9mm pistol compensators, suppressors, and thread protectors — pairs cleanly with the 3CR 9mm Micro Compensator or any common 1/2x28 9mm suppressor mount. Standard factory recoil springs work without adjustment; no need to retune the guide rod for stock-pressure loads.
Specs:
Break-in: 100-150 rounds of standard-pressure 9mm, then clean the chamber and locking lugs. Stainless will polish into a low-glare working finish after the first few hundred rounds — expected wear, not damage. If you're mounting a suppressor or comp, verify slide lockup with the device installed before live fire.
