Special Features
- Machined from 416R stainless steel, the same grade used in precision match barrels, the AC5049 provides superior dimensional consistency, corrosion resistance, and service life compared to standard carbon steel replacement barrels
- The black nitride finish is a thermochemical surface treatment that penetrates the steel rather than coating it, producing exceptional surface hardness and corrosion resistance that holds up under the high heat and gas exposure at the muzzle during suppressed fire
- The 1/2x28 thread pattern is the universal 9mm suppressor standard, making this barrel compatible with the full range of SilencerCo 9mm suppressors as well as virtually every other major brand of 9mm pistol can on the market
- The thread protector included with the barrel protects the thread crown when the suppressor is not installed, preventing damage that would make suppressor installation difficult or impossible
Practical Benefits
- The AC5049 is the required first component for any Glock 43 or 43X owner who wants to run a 9mm suppressor, as standard factory Glock barrels are not threaded and cannot accept a suppressor mount
- The drop-in fit requires no gunsmithing or fitting, allowing the owner to swap from the factory barrel to the threaded barrel in minutes using no tools beyond a standard field-strip procedure
- Important note: the shorter thread section on the Glock 43 barrel requires the use of the SilencerCo 1/2x28 SN piston (AC1756) rather than a standard Nielsen device piston. This piston must be purchased separately to complete a functional suppressor setup on this platform.
- The compact 3.70 inch length keeps the overall suppressed package as short as possible on the already slim Glock 43 and 43X platform, maintaining as much of the pistol's concealability as the suppressor allows
The SilencerCo Threaded Barrel (AC5049) is a dependable option for any Glock 43 or Glock 43X owner who wants a precision stainless steel threaded barrel to support suppressed shooting with a 9mm pistol can on one of the most popular compact carry pistols available.
