Glock 43X OEM Frame

Upgrade or build your Glock 43X with a factory-spec Glock 43X OEM Frame — the foundational lower receiver engineered to deliver trusted Glock handling, durability, and reliability. This frame accepts all proper 43X-pattern components, whether completing a new build or refreshing a worn lower.

Product Description | Specs for Glock 43X OEM Frame

The Glock 43X OEM Frame is molded from a rugged polymer blend engineered to endure everyday use and recoil forces while maintaining lightweight carry characteristics. Designed for the slimline 43X platform, this frame incorporates ergonomic texturing and contours optimized for concealed carry and rapid manipulation. It includes the pin bosses, rails, and geometry necessary to mount a 43X slide, locking block, and lower parts kit (LPK).

What’s Included For Complete OEM Frame

A complete OEM Glock 43X frame assembly normally includes:

• Serialized Glock 43X polymer frame

• Glock lower parts kit (LPK) including:

  • Trigger housing with ejector

  • Slide stop lever

  • Trigger with trigger bar

  • Connector

  • Magazine catch and spring

  • Trigger pin and housing pins

• Locking block and steel pins

• Reversible magazine release (Gen-5 style on 43X pattern)

• Front accessory rail on the dust cover
  (Actual included parts vary by supplier and build kit; verify specifics before purchase.)

What’s Included For Stripped OEM Frame (No LPK)

A stripped OEM frame provides the bare serialized polymer lower:

• Glock 43X polymer frame only
• Pin holes and bosses ready for LPK installation

Stripped frames do not include any internal parts, pins, or latch assemblies.

How to Install a Glock 43X OEM Frame

Install the Lower Parts Kit (LPK)

1. Ensure safety: confirm all components are unloaded and clear.
2. Drop in the trigger housing and insert the trigger/connector.
3. Install slide stop lever, magazine catch, and springs as per OEM schematic.
4. Install pins to retain internal parts.
5. Function-check trigger and magazine release for smooth operation.

Attach the Slide Assembly

1. Place the slide (barrel and recoil assembly installed) onto the frame rails.
2. Pull the slide fully rearward then release to lock into place.
3. Rack the slide several times to ensure proper travel and alignment.
4. Insert a magazine and perform a dry-function check (with dummy rounds if available) before live fire.

(Refer to Glock’s official LPK schematic for part orientation and order.)

How To Disable A Glock 43X OEM Frame

• Remove the slide assembly and store it separately (frame alone cannot function)
• Remove all magazines and store them separately
• Use a cable lock or trigger lock through the frame/magwell
• Store ammunition separately from the frame
• Lock the frame in a secure container or gun safe
• For permanent disabling: contact a licensed gunsmith or FFL (do not modify it yourself)

Compatibility

• Fits: Glock 43X and Glock 48 pattern slides/upper assemblies without modification.
• Parts Compatibility: Use 43X/48-pattern lower parts kits and Gen-5 style components (magazine catch, trigger group) where applicable.
• Magazines: 43X magazines (single-stack 9mm) fit this frame; standard G43 magazines do not interchange because of grip width differences.
• Gen Mix: Glock 43X is its own slimline platform; avoid mixing parts from other Glock generations or platforms without verifying fit.

What’s The Glock 43X OEM Frame Made Of?

The Glock 43X OEM Frame uses a proprietary polymer blend for impact resistance and durability while minimizing weight. The internal rail system includes metal inserts for slide rail wear resistance, and the frame geometry supports reliable lockup with the 43X slide assembly.

Customization Options

• Grip Texture: Aftermarket stippling or texture enhancements (performed by a qualified gunsmith) can improve control.
• Magazine Wells: Flared or extended magazine well inserts can be fitted to aid reload speed.
• Controls: Swap magazine release or slide stop levers with extended or ambidextrous OEM-compatible parts for personal preference.

Note: Modifications may affect warranty or serviceability; consult a qualified armorer.

FAQs

Q: Does this frame include internal parts?
Complete kits include internal parts and pins; stripped frames do not. Always verify what’s included before purchase.

Q: Will a Glock 43 slide fit this 43X frame?
The Glock 43 and 43X share single-stack geometry, but due to grip/frame width differences, standard 43 slides may not align perfectly on a 43X/48 frame. Always confirm compatibility.

Q: Can I use Glock 48 magazines in the 43X frame?
Yes; Glock 43X and 48 magazines are generally interchangeable in the slimline platform.

Q: Will installing a different lower parts kit change performance?
OEM-spec parts ensure reliable trigger and function; high-quality aftermarket kits are acceptable but test function before live fire.
