Looking to upgrade your Glock 43 or 43X with more accuracy, durability, and custom styling? This Glock 43/43X barrel is a high-performance replacement designed for shooters who want better results from their concealed carry or range pistol.

Built for Glock 43 & Glock 43X Compatibility
One of the most common questions Glock owners ask is whether the 43 and 43X barrels are interchangeable — and the answer is yes. Both models share the same barrel dimensions, making this barrel a direct-fit upgrade for either frame.
Compatible With:
- Glock 43
- Glock 43X
- G43/43X MOS variants
This makes it a great choice whether you're refreshing your EDC or building a personalized sidearm.
Key Features:
- Drop-in fit — no gunsmithing required
- Available in threaded and non-threaded options
- Built from match-grade stainless steel
- Precision rifling for improved accuracy
- Coating options include black nitride or gold TiN

Whether you want better groups at the range or a sleek aesthetic upgrade, this barrel is made to perform.
Threaded vs Non-Threaded – Which One Should You Choose?
If you're planning to run a compensator or suppressor, go with the threaded barrel (1/2x28) which includes a thread protector. If you want a cleaner look or you're focused on concealment, the non-threaded option is ideal.
