The Mosquito uses a DA/SA hammer-fired, simple blowback action with a fixed, non-threaded 3.9 inch steel barrel. This standard-length configuration delivers the classic Mosquito format with a 10+1 capacity in .22 LR.
Construction combines a medium-gray polymer frame with an aluminum-zinc alloy slide that incorporates steel inserts. The two-tone finish gives a clear visual contrast while retaining the practical durability benefits of the steel-reinforced slide design.
Controls and safeties include slide-mounted ambidextrous safety levers, a decocking lever, a magazine safety, and an internal locking device. The external hammer supports DA/SA operation for versatile range use.
Sighting is straightforward and adaptable: 3-dot contrast sights with an adjustable rear and interchangeable-height front blade. The slide-mounted safety levers are easily accessible, and the dust cover features a three-slot accessory rail.
Markings confirm its origin and importation: German proof and inspection marks with "DE" on the chamber area, "MADE IN GERMANY" on the pistol, and the importer mark "SIG SAUER INC EXETER - NH." Textured black polymer grips feature molded SIG SAUER logos for secure handling. The frame size is approximately 90% of a P226, offering familiar ergonomics in a lighter .22 LR format.
