At SHOT Show 2025, G100 unveiled their innovative modular handgun platform, the 120R Receiver. This open-source design integrates the locking block, slide spring seat, trigger housing, and slide rails into a unified metal frame, serving as the serialized core of the firearm. Compatible with GLOCK Gen3 components, users can install their preferred trigger group and slide lock into the receiver, secure it within a customizable grip module, and pair it with their chosen slide. The 120R Receiver is precision CNC machined from hardened steel and treated with black nitride for enhanced durability and corrosion resistance. Grip modules are 3D printed from durable Nylon 11 using Multi Jet Fusion technology, offering a balance of strength and customization. Designed and manufactured in Texas, the G100 platform emphasizes user configurability and compatibility with existing GLOCK parts.
