Glock 43/43X/48 – Zaffiri Blowhole Compensator – 9mm Black Nitride
PLEASE DOUBLE CHECK DETAILS AND FITMENT BEFORE PURCHASE.
The Zaffiri Precision Blowhole Compensator is built for slimline Glock 43, 43X, and 48 9mm pistols running a compatible 1/2x28 threaded barrel.
It is machined from 17-4 stainless steel, finished in black nitride, and designed to help redirect gas and add forward weight at the muzzle. The goal is simple: less muzzle climb, better control, and faster follow-up shots when the full setup is tuned right.
Small part, big job. Just do the grown-man thing and verify your barrel thread pitch before ordering.
Fitment
- Fits Glock 43, Glock 43X, and Glock 48 9mm pistols
- Requires a compatible 1/2x28 threaded barrel
- Designed for 9mm slimline Glock setups
- Designed to pair best with Zaffiri Precision slides, but barrel thread compatibility still matters most
Does NOT Fit
- Does not fit non-threaded barrels
- Does not fit barrels with thread pitches other than 1/2x28
- Does not fit Glock 17, 19, 19X, 26, 34, 45, or other double-stack Glock models

What It Does
- Redirects muzzle gases to help reduce muzzle rise
- Adds forward weight at the barrel end for better muzzle control
- Helps support faster follow-up shots when the pistol is properly tuned
- Gives slimline Glock builds a cleaner, more controlled comp setup
Why It’s Worth It
If you are building a Glock 43X or 48 with a threaded barrel, this is one of those upgrades that can make the gun feel flatter and more settled under recoil. It is not magic. It is gas, weight, tuning, and testing. The good stuff, not fairy dust.

Install Notes
Compensators can change how a pistol cycles. Depending on ammunition, recoil spring weight, slide mass, optic weight, lubrication, and break-in, your setup may need recoil tuning to run correctly.
Note: Recoil tuning depends on the full setup, including ammo pressure, compensator design, slide mass, optic weight, grip, lubrication, and break-in. Live-fire testing is mandatory.
Verify Before You Buy
- Verify your pistol model is Glock 43, 43X, or 48
- Verify your barrel is threaded 1/2x28
- Verify your local laws allow threaded barrels and compensators
- Verify your holster has enough clearance if you plan to carry with the compensator installed
- Function test with your actual ammunition before trusting the setup
