Zro Delta Modulus Extended Conversion Kit
The Zro Delta Modulus Extended Conversion Kit transforms your Modulus platform pistol into a full-size duty or competition configuration. Built around an extended-length slide assembly, this conversion system gives you the handling and sight radius advantages of a longer barrel and slide—useful whether you're running drills at the range, setting up a competition gun, or building out a duty-ready platform. If you're already invested in the Modulus system and want to expand its capabilities, this kit delivers the core components to make that happen.
The extended slide assembly measures 8 inches in length, a meaningful step up from compact Modulus frames and a dimension that accommodates faster sight tracking and more velocity from your chosen caliber. The extended dust cover and extended magwell complete the package, matching the geometry of the longer slide for a cohesive, functional appearance and improved ergonomics during reloads and transitions.
Zro Delta has built a reputation for modular, no-compromise components in the custom and competition communities. This conversion kit reflects that philosophy—it's designed for shooters who want to get more out of a single platform without starting from scratch. Whether you're chasing accuracy improvements, testing different configurations, or wanting a dedicated duty build alongside a carry gun, the Modulus Extended Conversion Kit is a straightforward way to do it.
