The FireFly uses a straight-blowback system in .22 LR paired with a DA/SA trigger, an external hammer, and a manual safety/decocker. The left-side push-button magazine release and 10+1 capacity support easy handling and operation.
Its 5-inch fixed steel barrel is threaded at the muzzle and fitted with a knurled thread protector. The slide is alloy, and the frame is polymer in a purple finish, complemented by black textured grip panels with GSG medallions.
Sight alignment is straightforward with fixed 3-dot iron sights featuring yellow inserts: a single-dot front blade and a two-dot rear notch. An integral under-barrel accessory rail offers mounting space for compatible lights or lasers.
Made in Germany and imported by American Tactical (Summerville, SC), this pistol bears CIP/DE proof marks on the barrel hood along with the importer mark. The FireFly platform is a continuation of the SIG Sauer Mosquito design, providing a familiar form factor in an updated package.
