Upgrade your SIG Sauer P938 with this factory 3.5” threaded barrel—precision-engineered to support suppressors and muzzle devices for optimal performance. Machined from high-quality materials and finished with Sig Sauer’s durable Nitron coating, this drop-in barrel transforms your micro-9 into a compact suppressor host. It includes a knurled thread protector and is compatible with direct-thread suppressors that use 1/2x28 muzzle threading and index at the muzzle.

Note: For optimal function, this barrel requires a suppressor piston that indexes off the muzzle face, not the shoulder. We recommend SilencerCo Part AC1756.

Whether you're enhancing your EDC setup or building the ultimate compact suppressed pistol, this SIG P938 threaded barrel delivers OEM quality and quiet performance in a reliable drop-in format.
