G43 Slide Parts Kit Overview

The G43 Slide Parts Kit contains every internal component needed to complete a stripped Glock 43 slide. Whether you’re building a subcompact 9mm for concealed carry, finishing a Polymer80 PF9SS project, or replacing worn internals on your daily carry gun, this kit eliminates the parts-hunting headache.

The Glock 43 set the standard for single-stack subcompact 9mm pistols: 6.26 inches long, just over an inch wide, and under 18 ounces unloaded. The G43 Slide Parts Kit gives you everything to build or rebuild the slide assembly on that platform. All components are manufactured to OEM specifications for direct drop-in fitment. Barrel and sights sold separately.

This G43 Slide Parts Kit is also compatible with G43X and G48 slides, which share the same internal components. One kit covers Glock’s entire single-stack 9mm Slimline series.

What’s Included in the G43 Slide Parts Kit

Complete Striker Assembly
Firing pin (striker), firing pin spring, firing pin spacer sleeve, spring cups, and channel liner. The striker is manufactured from hardened stainless steel with a black nitride finish for corrosion resistance and consistent ignition.

Extractor Components
Extractor with loaded chamber indicator (LCI), extractor depressor plunger, extractor depressor plunger spring, and spring-loaded bearing. Hardened steel construction ensures reliable extraction through thousands of rounds.

Safety Components
Firing pin safety (drop safety) and firing pin safety spring. These components are critical to the Glock Safe Action system, preventing discharge unless the trigger is fully pressed.

Recoil Assembly
Dual recoil spring assembly with captured guide rod. The G43’s dual spring design helps manage recoil in the lightweight subcompact frame while maintaining reliability across a wide range of ammunition.

Finishing Components
Slide cover plate (backplate) to complete the assembly. Ready for installation with no additional parts required beyond barrel and sights.

What Makes the G43 Slide Parts Kit Different

Complete Single-Stack Coverage
The G43 Slide Parts Kit works across Glock’s entire Slimline 9mm series. G43, G43X, and G48 all use identical slide internals. One kit handles your subcompact carry build, your 10-round G43X project, or your longer-slide G48 setup.

Concealed Carry Ready
The Glock 43 platform was purpose-built for everyday carry. At just over an inch wide and under 18 ounces empty, it disappears under a t-shirt. The G43 Slide Parts Kit lets you build or maintain that capability with quality components manufactured to factory specifications.

PF9SS Compatible
Building on a Polymer80 PF9SS frame? The G43 Slide Parts Kit drops right in. Combined with a G43-compatible slide and barrel, you have everything needed to complete the upper assembly on your single-stack build.

No Fitting Required
Every component in the G43 Slide Parts Kit is manufactured to OEM tolerances. No hand-fitting, no polishing, no gunsmith required. Install the parts, function check, and carry with confidence.

G43 Slide Parts Kit FAQ

The kit includes: firing pin (striker), firing pin spring, firing pin spacer sleeve, spring cups, firing pin channel liner, firing pin safety, firing pin safety spring, extractor with LCI, extractor depressor plunger, extractor depressor plunger spring, spring-loaded bearing, slide cover plate (backplate), and dual recoil spring assembly with guide rod. Barrel and sights are not included.
Is the G43 Slide Parts Kit compatible with G43X and G48?
Yes. The Glock 43, 43X, and 48 all use the same slide internal components. This G43 Slide Parts Kit is fully compatible with all three Slimline models.
Will the G43 Slide Parts Kit work with Polymer80 PF9SS builds?
Yes. The G43 Slide Parts Kit is fully compatible with Polymer80 PF9SS frames when paired with a G43-compatible slide and barrel. All components are manufactured to OEM specifications for direct drop-in fitment.
Does the G43 Slide Parts Kit include a barrel?
No. The kit includes slide internals only. You will need to source a G43-compatible barrel and sights separately to complete your slide assembly.
Is the G43 Slide Parts Kit a firearm or regulated component?
No. The G43 Slide Parts Kit contains small parts and springs only. These are not firearms or firearm frames/receivers. No FFL transfer is required. The kit ships directly to your door.
What tools do I need to install the G43 Slide Parts Kit?
Basic assembly requires a 3/32″ punch, a nylon or brass hammer, and a flat surface. A Glock armorer’s tool or front sight tool is helpful but not required for slide internals installation. Most builders complete installation in under 30 minutes.
Are these OEM Glock parts?
No. These are aftermarket components manufactured to OEM Glock specifications. They are not produced by or affiliated with Glock, Inc. All parts are made to the same dimensions and tolerances as factory components for direct drop-in fitment.
What’s the difference between G43, G43X, and G48 slides?
The G43 is the original subcompact with a shorter grip and 6-round magazine. The G43X has the same slide length but a longer grip accepting 10-round magazines. The G48 has both a longer slide and longer grip. All three use identical slide internal parts, so this G43 Slide Parts Kit works with any of them.
