Glock 43 / 43X – Threadless Comp + Barrel Kit – Ball-Vise – 3.9"
PLEASE DOUBLE CHECK DETAILS AND FITMENT BEFORE PURCHASE.
Made by Zaffiri Precision, this Threadless Comp + Barrel kit gives your Glock 43/43X compensated performance without a traditional threaded barrel. It uses Zaffiri’s Ball-Vise locking system (steel ball bearing + set screw) to clamp the comp to the included barrel—so you get flatter tracking, faster follow-up shots, and a clean setup that doesn’t rely on timing a threaded comp.
Available options are organized below under Variants.
Fitment
- Fits: Glock 43 / Glock 43X (9mm)
- System note: Comp is compatible only with the provided ZP Threadless Comp Barrel (matched set)
Does NOT fit
- Not for Glock 48 unless specifically listed as a 48 variant
- Not intended to mix with non-Zaffiri “threadless” barrels or other comp systems
What it does
- Uses a 120° port opening to redirect gas and reduce muzzle rise.
- Mass-forward design adds front weight to help keep the muzzle down during fast strings.
- Threadless design bypasses thread pitch/timing headaches.
Why it’s worth it
- Threadless convenience: no timing washers, no thread drama—align, torque, cure, run.
- Matched kit: comp + barrel are designed to work together.
- Cleaner build: keeps the front end compact and purpose-built for the 43/43X platform.
