Upper Parts Kit

Glock 43/43X/48 Upper Parts Kits

Upper parts kits for Glock 43, Glock 43X, and Glock 48 slide builds, replacements, and repairs. These are the small internal slide components that help complete a compatible upper assembly — not flashy, not loud, just necessary.

If you are building a slimline Glock slide, replacing worn parts, or finishing an aftermarket upper, this is where fitment matters. Glock 43, 43X, and 48 parts live in their own lane. Do not mix them with Glock 17/19 parts and expect the gun gods to forgive you.

Fitment Warning — Read Before Buying

These upper parts kits are intended for compatible Glock 43, Glock 43X, and Glock 48 slimline slide setups. Always verify your exact model, slide generation/configuration, and aftermarket slide compatibility before ordering.

These parts are not for Glock 17, Glock 19, Glock 26, Glock 34, or other double-stack Glock models. Wrong parts create bad builds, bad function, and returns nobody wanted.

Good For

  • Completing Glock 43, 43X, and 48 compatible slide builds
