Zaffiri Precision
Building a custom Glock 43, 43X, or 48? A Zaffiri Precision upper parts kit for Glock 43/48 gives you all the internal components you need to complete a precision slide without hunting down individual parts. Whether you're assembling a carry gun, a range trainer, or a competition build, having a matched set of quality internals ensures reliable function and proper fitment from the start.
This kit is purpose-built for the Glock 43, 43X, and 48 platform—three of the most popular compact and subcompact pistols for concealed carry and defensive use. Rather than source a firing pin from one vendor, an extractor from another, and hope everything plays nice together, Zaffiri has engineered these components as a system. That attention to detail is what separates a reliable build from a parts-bin nightmare.
Installation requires gunsmith-level competence; this is not a do-it-yourself project for novices. The precision tolerances and safety-critical nature of upper receiver internals mean you should have a qualified armorer handle the work. Once installed, you'll have a complete, properly functioning upper assembly ready for your preferred barrel and frame setup.
| Fit | Glock 43, 43X, 48 |
| Components | 7-part upper internals kit |
| Installation | Requires professional gunsmith installation |
This kit is designed specifically for the Glock 43, Glock 43X, and Glock 48. Do not attempt to use it in other Glock platforms, as fitment will be incorrect and the gun may not function safely.
No. This kit should be installed only by a competent gunsmith or qualified armorer. Upper receiver internals are precision-fitted and safety-critical components; improper installation can result in malfunction or injury. Take it to a professional.
Yes, the complete extractor included in this kit features the loaded chamber indicator (LCI).
This kit provides the upper internals only. You will still need a completed slide, barrel, frame, fire control group, and any other components to assemble a complete pistol. Consult with your gunsmith about what else is required for your specific build.
