Glock 43 / 43X – Threaded Barrel – 9mm – 1/2x28 Black Nitride


PLEASE DOUBLE CHECK DETAILS AND FITMENT BEFORE PURCHASE.

The SilencerCo threaded barrel for Glock 43 and Glock 43X gives you a suppressor-ready 9mm upgrade built from 416R stainless steel with a black nitride finish. This is the 1/2x28 version made for shooters who want a clean drop-in barrel upgrade with the thread pitch most people are actually looking for.

This barrel includes a thread protector. Because of the shorter thread setup on the Glock 43 family, SilencerCo also notes that this model uses the 1/2x28 SN piston when paired with a suppressor.


Fitment

  • Fits Glock 43 and Glock 43X pistols chambered in 9mm
  • Drop-in style threaded barrel
  • Compatible thread pitch: 1/2x28
  • SilencerCo notes Glock 43 barrel setups require the 1/2x28 SN piston for suppressor use

Does NOT fit

  • Does not fit Glock 43X MOS as an optic issue is irrelevant here, but buyers still need to verify barrel fit with their exact slide and generation setup
  • Do not assume fit for Glock 48 or other slimline models not specifically listed
  • Piston is not included

What it does

This barrel gives the Glock 43/43X platform suppressor-ready threading while keeping a true drop-in format for easier installation.


Why it’s worth it

It is a clean way to turn a slim Glock into a threaded setup without gambling on mystery-barrel tolerances. SilencerCo makes this one from 416R stainless and keeps the specs straightforward.

Install notes

Verify exact pistol model before ordering. If the buyer plans to run suppressed, they also need the correct piston setup. Barrel fit is not where you freestyle and hope for the best.


Verify before you buy

Verify Glock 43 or Glock 43X fitment, verify 1/2x28 thread needs, and verify suppressor piston compatibility before purchase.
