The serialized UFC removable chassis is the core of the ONE system. It carries the model marking and serial, allowing the grip frame and other external modules to be swapped while keeping the same legal firearm component. The frame is marked MULTI-CAL, highlighting the platform’s design for modular conversion within the ONE ecosystem.
The compact slide measures 4.01 inches and uses a faceted profile with lightening windows near the muzzle to reduce mass. An optics cut with a cover plate comes installed from the factory, and the slide wears a matte black finish paired with a fixed front post.
Controls and ergonomics include ambidextrous magazine-release buttons, a trigger safety, stippled grip panels, and a flared magwell funnel that is already installed. The dust cover uses a removable/modular section with a Picatinny rail for mounting compatible accessories, and the pistol ships with extra grip and rail modules for fine-tuning.
Manufactured in the USA and marked ZRODELTA Rutherford College, NC, this example reflects the ONE series announced at SHOT Show 2022. The platform was designed for broad modularity, including the optional PCU for interfacing the UFC with AR-15 pattern components (not included).
