What makes the GST-9 “modular”?
The GST-9 features a revolutionary two-part frame system. The serialized fire control chassis houses all critical components, while the interchangeable grip module defines the ergonomics. This allows you to swap between compact, full-size, and other grip profiles on a single registered chassis, a feature unmatched by traditional builds.
What additional parts do I need to complete it?
This is an 80% build kit. You will need to source a slide, barrel, recoil spring assembly, lower parts kit (LPK), and magazine separately. All internal parts are compatible with widely available Glock® Gen 1-3 components, giving you immense flexibility in selecting performance and budget-oriented parts.
Is the JIG® easy to use for a first-time builder?
While the included P80 JIG® system is precision-machined and guides the process, completing an 80% frame requires careful machining (drilling and milling) with basic tools. It is recommended for individuals with strong mechanical aptitude. Always follow the manufacturer’s instructions precisely and ensure compliance with all federal, state, and local laws.
What is the advantage of an OD Green frame?
The OD Green finish offers a distinctive tactical aesthetic that stands apart from standard black. Beyond looks, the color provides practical benefits in certain outdoor environments and the polymer is dyed throughout, meaning holster wear or minor scratches won’t reveal a different color underneath.
