Welcome! The Mosquito is no longer available from SIG. SIG also doesn't support this platform anymore. The pistol was made for SIG by GSG (German Sports Guns Gmbh), and it is currently being imported by American Tactical Inc. (ATI) as the Firefly. Contact ATI directly for parts and service info.hello. looking information on parts for a sig mosquito. i have one, need a replacement magazine catch. new to the site, hoping for someone to point me in the right direction. thanks everyone in advance.
