Barrel Thread Sizes & Suppressor Compatibility Guide

What thread sizes are your barrels, and which suppressors are compatible?

All META Tactical barrels have the following thread sizes:

  • 9mm caliber barrels: ½” x 28 thread

  • 10mm/.40 caliber barrels: 9/16” x 24 thread

  • .45 caliber barrels: .578” x 28 thread

Direct-Thread Suppressor Warning

⚠️ Important: Direct-thread suppressors can only be used with META Tactical extended barrels.
If using a standard length threaded barrel, the suppressor may cause clearance issues or fail to fit within the standard muzzle shroud.
