The ZRODelta Modulus Modular 9mm Pistol puts the power of customization back into the hands of the shooter while evolving the concept of "modularity." Imagine a high-performance pistol that can be configured from a compact to a duty to a long slide race gun in a matter of seconds – the ZRO Modulus is that pistol. Not only is the system compatible with the most common Gen 3 parts but it also is extremely accurate, thanks in part to the rigid 7075 Billet frame and additional rail engagement found within ZRO Delta's Patent Pending Design.
