Description
This pistol is not a production model, nor was it ever intended to be one.
The Prototype SIG P226 X-Five Honeycomb is a true Mastershop design study, a singular exploration of form, structure, and modern machining executed at the highest level of German precision. According to the accompanying factory letter from SIG Sauer Mastershop, this pistol was created specifically as a design study for the IWA Show 2018, displayed alongside only a small handful of other experimental Mastershop concepts.
What immediately sets this piece apart is the striking honeycomb slide geometry, a carefully engineered pattern that transforms the slide into both a visual statement and a technical showcase. The pattern is not decorative; it demonstrates structural possibilities, light interplay, and surface rhythm that reflect SIG Sauer’s forward-thinking design philosophy. Finished in a refined silver tone, the slide contrasts beautifully with the sculpted frame and richly grained wooden grips, creating a balance between modern industrial design and classic craftsmanship.
Built on the proven P226 X-Five platform and chambered in 9mm, this prototype retains the unmistakable handling characteristics and mechanical precision the X-Series is known for, while pushing far beyond standard production boundaries. Every component exhibits Mastershop level execution, with exceptional fit, finish, and attention to detail throughout.
The included documentation confirms this pistol as a unique design study, produced to explore new ideas in slide structure and manufacturing techniques, an object meant to inspire future possibilities rather than follow existing templates. All serialized components are factory-matched, reinforcing its integrity as a cohesive, original Mastershop creation.
This is not simply a rare SIG Sauer, it is a moment in the brand’s design history. A one-off artifact from a period when the Mastershop was openly experimenting, questioning convention, and demonstrating what could be achieved when cost, time, and production limits were set aside.
For the collector who values originality, provenance, and true prototype status, the P226 X-Five Honeycomb stands in a category of its own.
