Arm Or Ally Frame Completion Lower Parts Kit for Glock 43 / 43X

Arm Or Ally Frame Completion Lower Parts Kit for Glock 43 / 43X

Complete or rebuild a compatible slimline pistol frame with the Arm Or Ally Frame Completion Lower Parts Kit for Glock 43 / 43X. This kit brings together the essential trigger components, controls, pins, and springs needed to finish a stripped frame or replace worn lower-frame parts in an existing build.

Designed around Glock 43 and Glock 43X-pattern specifications, the kit is suitable for compatible factory-style and aftermarket frames. Its slimline-specific components are sized for the narrower frame architecture used by these compact 9mm platforms rather than the larger components found in Glock 17 or Glock 19-pattern pistols.

The included polymer trigger is assembled with a polished trigger bar to simplify installation and provide a smoother contact surface within the fire-control system. The trigger housing arrives with the ejector installed and is paired with the connector, trigger spring, slide stop lever, slide lock assembly, frame pins, and magazine-control components required for frame completion.

This kit provides a straightforward option for completing a new compatible frame, refreshing a high-round-count pistol, or keeping commonly needed replacement parts available at the workbench. Components are manufactured to consistent dimensional specifications to support proper fit and reliable operation when correctly installed.

Please note: Glock 43 and Glock 43X frames use different magazine catches because the magazine and grip dimensions are not identical. Install only the magazine catch intended for the specific frame being completed. A locking block and frame rails are not included unless specifically shown or stated with the product.
