G43 Slide Parts Kit

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.
