Sig Sauer Mosquito 22LR Rimfire Pistol with Threaded Barrel and Rail

This Sig Sauer® Mosquito® comes with a threaded barrel (M9 x 0.75), and it’s only 90 percent the size of a P226®. The Mosquito® is a great choice for hours of shooting fun with its wear-resistant polymer frame and integral accessory rail - ergonomically designed to enhance accuracy and provide a better all-around shooting experience.

Additional features include a rugged blowback system, fixed barrel and adjustable sights. It’s also loaded with safety features that include a decocking lever and the automatic drop safety you would expect in a Sig Sauer® pistol. It’s further enhanced with an ambidextrous manual slide mounted safety, magazine safety and internal locking device. An optional Threaded Barrel Adapter facilitates the mounting of accessories requiring a ½ x 28 thread pattern, including many popular sound suppression devices.
