Sig Sauer Mosquito .22 LR DA/SA Semi-Auto Pistol, 3.9 Inch Barrel, Two-Tone Metallic Purple/Matte Gray, German-Made
German-made with CIP proofs and importer markings, this Sig Sauer Mosquito is a .22 LR, DA/SA, blowback-operated pistol built as an approximately 90% size analog to the SIG P226. It features a two-tone look with a metallic purple polymer frame and matte dark gray slide, a 3.9-inch fixed steel barrel, and a windage-adjustable rear sight.

The Mosquito uses a semi-automatic, blowback-operated, DA/SA system with an exposed hammer and a decocking lever, mirroring the familiar SIG P-series control layout (slide catch, decocker, takedown). It is approximately 90% the size of the SIG P226, providing a similar in-hand feel in a .22 LR platform.
Construction details include a 3.9-inch fixed steel barrel and a matte dark gray slide with rear serrations. The polymer frame is finished in metallic purple and wears textured wrap-around grips with SIG SAUER logos for a secure hold.
Sights are straightforward and practical: a fixed front sight with a single yellow/green dot paired with a square-notch rear sight adjustable for windage. An integral accessory rail with four cross-slots is built into the frame to support compatible accessories. Capacity is 10+1 with the included magazine.
Safety features are comprehensive: a slide-mounted manual safety, decocking lever, firing-pin safety, magazine disconnect, and an integral key-operated lock. Origin and markings include German CIP proofs (eagle over N and DE country code), a SIG SAUER INC EXETER – NH importer mark, and a MADE IN GERMANY marking.
