Are Glock 43 and 43x Slides the Same?
The Glock 43 (G43) and 43x are both highly popular single-stack 9mm pistols from Glock. While they share some similarities, there are distinct differences between the two. One of the main inquiries among Glock enthusiasts is: Are Glock 43 and 43x slides interchangeable? In this article, we’ll delve into the details to provide a straightforward answer.
Similarities
Before we dive into the differences, it’s essential to acknowledge the shared characteristics between the G43 and 43x. Some of the key similarities include:
- Calibre and Action: Both pistols operate in 9mm Para and have a short reset trigger.
- Steel Frame: Both Glocks feature a durable and recoil-resistant steel frame.
- Single-Stack: Both pistols have a compact single-stack design for minimized width and increased concealment.
- Compact Grip: Both pistols have the same compact grip dimensions to accommodate smaller hands and tighter carry.
Differences
Now that we’ve covered the similarities, it’s time to discuss the differences between the Glock 43 and 43x slides.

The Unifying Factor: The slide
Now that we’ve covered the differences between the two pistols, the slide is where the common bond lies. Yes, the Glock 43 and 43x slides are interchangeable to an extent. However, to clarify, there are minor differences in the slide production process and design:
Slide Differences:
Glock 43
- Standard RIB (Reinforcement Internal Barrel) design which provides a more pronounced taper and a slightly narrower silhouette.
- Non Threaded Barrel option in the standard configuration.
Glock 43X
- Mid-Profile Cutout (X-Out) design allowing users to install optics.
- Threaded Barrel (1/2"-36) for suppressor accessories.
Conclusion: Partial Interchangeability
From the above information, while the Glock 43 and 43x slides do share some similarities, such as the same 1:10 RH twist (right-hand twist) steel barrel and the same rail pattern, there are distinguishable differences in their design and production process, mainly due to the design requirements for the Glock 43x’s optics cuts and threaded barrel. The slides are not perfectly interchangeable, but can work together with some compromise for users who want to make modifications.
Work-Arounds and Solutions:
For those interested in swapping slides, some may opt for a third-party slide conversion or fabrication shops that can modify slides between the two models. Users should be aware of legal implications, potential compatibility issues, and the void of warranty when modifying slides on their Glock pistols.
Keep in mind that some online forums and communities suggest manual modifications to make the 43x slide compatible with the 43’s gun frame. While tempting, these modifications should not be attempted and may void the pistol’s warranty.
In our conclusion, while the Glock 43 and 43x slides share some common qualities, they are distinguishable with deliberate design choices. Although work-arounds exist, I strongly advise against unauthorized conversions or modifications to the guns. Instead, we advise users to explore and adapt to the unique characteristics that each pistol offers, giving you the best chance at optimal performance and functionality within the Glock ecosystem. If you have any doubts about your Glock pistol’s interoperability, consult the nearest authorized Glock dealer or supplier for guidance.
