GSG Firefly (Sig Mosquito) .22LR Long Barrel Semi-Auto Pistol UK Section 1


Based on the classic Sig Sauer Mosquito this handgun has already proved popular in the US and will also prove a popular piece for UK shooters.”

The GSG Firefly is built on a rugged polymer frame with black plastic hand grip panels. The single stack metal magazine holds 10 rounds, and has a safety system that prevents the slide, hammer and trigger from being operated when the magazine is ejected. A rail allows for tactical accessories to be added and blowback system ensures an incredibly smooth operation, while the adjustable rear sight ensures it can be adapted to individual use.

The Firefly, which has been especially adapted to make it legal for the UK market, has a 30cm barrel with an extension on the grip to bring it up to the 60cm required by law. The handgun weighs just under 3lb, making it a light, practical option for those competing in tactical competitions.

Available in Black, Tan & OD Green – Limited Stock.
