Glock 43 / 43X / 48 – 9mm Compensator – 1/2x28 – Blowhole

PLEASE DOUBLE CHECK DETAILS AND FITMENT BEFORE PURCHASE.

From Zaffiri Precision, the Blowhole compensator is a slimline Glock-ready 9mm comp designed to reduce muzzle rise by redirecting gas upward—keeping your dot/flame front sight flatter and your follow-up shots faster. It’s built from tough 17-4 stainless and is designed to have the best fit with Zaffiri slides, but it will run on compatible Glock 43/43X/48 setups that meet the thread and barrel requirements below.

Available options are organized below under Variants.

Does NOT fit

  • Does not fit non-threaded barrels
  • Does not fit barrels that are not 1/2x28
  • Not for Glock 42

What it does

  • Redirects gas upward to help counter muzzle climb for flatter shooting.

  • Most noticeable benefit shows up with dot guns and fast strings.

Why it’s worth it

  • Real performance upgrade if you actually shoot hard and want faster return-to-zero.

Install notes

Verify before you buy

  • You’re running a Glock 43 / 43X / 48 platform (not a different Glock family).
  • You understand this may require tuning for perfect reliability (ammo + recoil spring).

⚠ Install & Compatibility Disclaimer: Compensators change slide dynamics and may require tuning (ammo selection and/or recoil spring assembly weight) to ensure reliable cycling.
