Developed for police and government contracts, this limited-edition AEU model retains all duty-grade features while offering collectors true agency provenance. The pistol’s serialized stainless-steel Fire Control Unit (FCU) is housed in a full-size polymer grip module with wrap-around stipple texture for confident purchase.
The factory-installed ROMEO1PRO optic pairs with raised XRAY3 day/night sights for an absolute co-witness sight picture, giving shooters immediate redundancy and rapid target acquisition in any light.
A 4.7 in stainless barrel, matte-black Nitron slide with aggressive front and rear serrations, and a flat-faced trigger deliver consistent, controllable performance. Ambidextrous slide-catch levers and a 5-slot MIL-STD-1913 rail expand adaptability for left- or right-handed users and duty accessories.
Internal striker and disconnect safeties, along with the proven striker-fired action, maintain SIG’s reputation for reliability while keeping the trigger pull crisp and repeatable. With its limited Agency Vault pedigree, this RXP Pro stands out as both a capable service pistol and a desirable addition to any modern SIG Sauer collection.
