Arm Or Ally Frame Completion Lower Parts Kit for Glock 17 / 19

Gen 1–3 Compatible

Complete a full-size or compact Gen 1–3-compatible pistol frame with the Arm Or Ally Frame Completion Lower Parts Kit for Glock 17 / 19. This comprehensive kit brings together the trigger components, controls, pins, and springs required to finish a compatible stripped frame or replace worn internal parts in an existing build.

Compatibility includes Glock 17 and Glock 19 Gen 1–3-pattern frames, Polymer80 PF940V2 Full Size and PF940C Compact frames, and SCT Compact frames. Both Glock 17 and Glock 19 slide lock springs are supplied, allowing the appropriate spring to be selected for either the full-size or compact configuration.

The included polymer trigger arrives assembled with a polished trigger bar, reducing the number of individual components that must be prepared during installation. A trigger housing with a Gen 4 ejector already installed is also included, along with the connector, trigger spring, slide stop lever, magazine catch assembly, frame pins, and remaining controls needed for frame completion.

This kit is an effective option for a new compatible frame build, refurbishing a well-used pistol, or keeping essential replacement parts available at the workbench. Each component is manufactured to consistent dimensional specifications to support proper fit, reliable movement, and dependable operation when correctly installed.

Please note: A locking block is not included. Polymer80 frames may also require frame-specific pins or components originally supplied with the frame. Confirm that all required parts are present and compatible with the exact frame before beginning assembly.
