Frequently Asked Questions
Why upgrade the barrel on a Glock 43 or 43X?
Aftermarket barrels offer tighter tolerances, improved accuracy, and the option for threaded muzzles. Whether you're building a carry pistol or suppressor-ready setup, a barrel upgrade gives you more control and performance.
Are these barrels drop-in ready?
Yes. All NDZ barrels for the Glock 43 and 43X are true drop-in components, no fitting required. Swap in and go.
What are the benefits of a threaded barrel?
A threaded barrel allows you to attach a suppressor or compensator. It’s a must-have for custom builds focused on recoil control, sound suppression, or competition use.
Do Glock 43 and 43X use the same barrels?
Yes. Both models share the same slide and barrel dimensions, so any NDZ barrel listed for G43/G43X will fit both platforms.
Will an upgraded barrel affect reliability?
No. NDZ barrels are precision-machined and rigorously tested to ensure proper lockup, cycling, and reliability across standard and defensive loads.
