Frequently Asked Questions
Sig Sauer Mosquito for sale
Is the SIG Sauer mosquito discontinued?
Yes, SIG Sauer discontinued the Mosquito rimfire pistol. German Sport Guns, the original manufacturer, now sells a successor called the GSG Firefly through American Tactical Imports. Used Mosquito pistols remain available from some retailers, though new SIG-branded units are no longer produced.
What is a SIG sauer mosquito?
The SIG Sauer Mosquito is a discontinued compact .22 LR blowback pistol built by German Sport Guns (GSG), not SIG Sauer. It is modeled at 90% scale of the SIG P226, features a polymer frame and zinc-alloy slide, holds 10 rounds, and is available on the used market.
Is a SIG Mosquito a good gun?
Whether it's good depends on your needs. Owners praise its accuracy, fixed barrel design, and cheap .22 LR ammunition costs, making it solid for plinking and range work. Controls are well-designed. The DA/SA trigger pull runs heavy for some shooters. Currently discontinued but available used, typically around $363.
What replaced the SIG Mosquito?
SIG Sauer discontinued the Mosquito, and American Tactical Imports began importing the same pistol rebranded as the GSG FireFly. It is a direct continuation, not merely a spiritual successor — ATI described it as the .22 pistol formerly known as the SIG Mosquito under new GSG FireFly branding.
Does the SIG Sauer mosquito have a threaded barrel?
The SIG Sauer Mosquito was available with a threaded barrel (M9 x 0.75) on certain variants, allowing suppressor attachment. Not all models included this feature. The threaded barrel version faced legal restrictions in some states, including California.
What is the best 22 ammo for the Sig Sauer mosquito?
CCI Minimags and Stingers perform well in the Mosquito, though some users report occasional failures. Winchester M22 and plated rounds also work reliably. Higher-end loads typically cycle more consistently. Keep the gun clean and run several rounds through it before expecting reliable function.
How many rounds does a SIG Sauer mosquito hold?
The SIG Sauer Mosquito holds 10 rounds of .22 LR ammunition in its single-stack magazine.
