Sig Sauer
The Sig Sauer P938 9mm Luger 3.50" threaded barrel with protector is the factory-original upgrade path for P938 shooters who want suppressor-ready capability. This is the real Sig part—not an aftermarket copy—engineered to the same exacting standards as your pistol. If you're building a dedicated suppressed carry gun, upgrading a worn barrel, or simply want the flexibility to run a muzzle device, this threaded barrel delivers the precision fit and durability Sig is known for.
The 3.50" barrel is chambered in 9mm Luger and features a .5x28 TPI thread pitch—the standard for 9mm suppressors and muzzle brakes. A knurled thread protector cap is included, so your threads stay clean and protected when you're running the gun unsuppressed. The barrel is specially heat-treated for toughness, meaning it's built to handle the pressures of suppressed fire and the wear of regular use without compromise. Sig's factory heat-treatment process goes beyond standard steel and ensures long service life.
Drop-in replacement means no gunsmithing required—if you've already owned a P938, you know how straightforward a barrel swap can be. Whether you're a suppressor enthusiast, a quiet-shooting hunter, or someone who values the option to add a muzzle device down the road, this is the OEM barrel that makes it simple.
