The Glock 43X OEM Complete Slide is a factory-assembled slide built to Glock tolerances and shipped complete with barrel, recoil spring assembly, and factory internals. Ideal for a drop-in replacement, repair, or a turnkey upgrade ready to mount and function when paired with a compatible Glock 43X frame.

How To Install The Glock 43X OEM Complete Slide

Safety first: Work on a clean surface, wear eye protection, and confirm the firearm is unloaded. Follow all local laws and manufacturer instructions. If unsure, consult a qualified gunsmith.

• Confirm the slide assembly matches your Glock 43X generation and frame.
• Ensure the firearm is completely unloaded (magazine out, chamber checked).
• Align slide assembly on the frame rails and carefully rack the slide into place per Glock assembly procedure.
• Perform an unloaded function check: rack the slide, check slide lock, dry-fire (per local laws), and verify manual functions.
• If fitted with new sights, confirm sight alignment and zero at a safe range.
• If anything binds or operates unusually, stop and have a qualified gunsmith inspect.

How To Disassemble The Glock 43X OEM Slide (Service & Maintenance)

       IMPORTANT: Always ensure the firearm is unloaded and pointed in a safe direction.

• Remove magazine and lock the slide open; visually and physically confirm the chamber is empty.
• Follow Glock takedown steps to remove the slide from the frame.
• Remove the barrel and recoil spring/guide assembly for cleaning and inspection.
• Keep small parts organized; inspect extractor, firing pin channel, and other internals for wear or fouling.
• Reassemble in reverse order or consult a gunsmith for deeper servicing.

What Is The Glock 43X OEM Slide Made Of

Glock manufactures the 43X slide from high-strength steel and applies a factory nitride (nDLC/salt-bath) finish designed to increase surface hardness, resist corrosion, and reduce glare. All factory-installed internals meet Glock’s specifications for reliable, consistent performance.

Customizations & Upgrades

Common options

• Sights: Swap factory sights for aftermarket dovetail or night sights.

• Optic upgrades: If the listing shows “optic-ready,” install the correct optic plate and red-dot per the optic maker’s instructions.

• Coatings: Send the slide to a professional for Cerakote or other refinishing to add color and protection.

• Professional milling: Hire a reputable gunsmith to add ports, lightening cuts, or optic cuts — permanent structural changes can affect safety and warranty.

Note: Permanent milling or structural modification can void the factory warranty and affect safety. Always use a qualified gunsmith for non-trivial work.
