Complete lower parts kit for the Glock 43 — every internal frame component you need to build out a stripped Glock 43 lower in a single package. Drop-in fit on factory G43 frames with no hand-fitting required.

This is the OEM-spec internals set: trigger with trigger bar, trigger housing with connector and spring, slide lock and spring, magazine catch with spring, trigger pins, and the slide stop lever. Everything pins and pivots exactly where the Glock factory parts do, so a standard G43 slide and barrel will run on the assembled lower with no adjustments.

Kit contents:

• Trigger with trigger bar
• Trigger housing with connector
• Trigger spring
• Trigger pin and trigger housing pin
• Slide lock and slide lock spring
• Magazine catch and magazine catch spring
• Slide stop lever

Fits: Glock 43 frames. Single-stack platform — the kit will not work in a Glock 43X or Glock 48 frame because the magazine catch and trigger housing geometries differ. Locking block is not included — source the OEM Glock 43 locking block separately.

Use notes:

• Function-check the trigger reset, slide lock engagement, and magazine drop on an empty pistol after assembly
• Inspect the slide stop lever spring for full seating — a partially seated spring will let the slide release intermittently during recoil
• Dry-fire 50-100 cycles before live fire to break in the connector
