Description
The GSG Firefly 22LR Smoke Grey Pistol is a full-size, hammer-fired .22 LR handgun from German Sport Guns, imported by American Tactical, pairing a black slide with a smoke grey alloy frame and a threaded 4.9-inch barrel.

GSG Firefly 22LR Smoke Grey Pistol Overview
German Sport Guns built the Firefly to give rimfire shooters the feel of a full-size service pistol without the cost of centerfire ammunition. This model (MFG GERG2213TFFSA, UPC 810113113975) uses a double-action/single-action trigger, an alloy frame with a black polymer grip, and an adjustable rear sight. It holds 13 rounds in the magazine plus one in the chamber, weighs about 24.6 ounces, and measures 7.2 inches overall. The 4.9-inch barrel is threaded 9x.75mm, and a 1/2×28 thread adapter is included so common rimfire muzzle devices can be fitted.
Smoke Grey Finish and Handling
The smoke grey frame is an applied finish over alloy, set against a black slide, so the gun looks different from the all-black rimfire pistols on most shelves. The grip profile is generous, which suits medium and large hands, and the ambidextrous thumb safety works for left-handed shooters as well as right-handed ones. Expect the finish to show holster wear over time, as applied coatings do on any alloy-framed pistol.

Trigger and Sights
The DA/SA action means the first shot can be fired with a longer, heavier double-action pull from the hammer-down position, and follow-up shots break single action. That makes the Firefly a useful trainer for anyone who carries or competes with a DA/SA centerfire gun. The rear sight adjusts for windage and elevation, so you can zero it to the bullet weight and velocity your gun likes best.
Threaded Barrel and Muzzle Devices
The threaded muzzle lets the Firefly serve as a suppressor host or wear a thread protector or compensator. A suppressor is an NFA item: you will need an approved ATF Form 4, a tax stamp process, and a state that allows ownership. Rimfire ammunition is dirty, so a can on a .22 pistol needs regular cleaning. Without a muzzle device, keep the thread protector installed to guard the threads.

Reliability and Ammunition Choice
Like most blowback rimfire pistols, the Firefly can be picky about ammunition. Standard and high-velocity 40-grain round-nose loads from major makers generally run best, while very light or subsonic target loads may not cycle the slide reliably. Plan on a break-in period of a few hundred rounds, keep the chamber and extractor clean, and avoid mixing ammo brands in one magazine while you learn what your pistol prefers.
Range Use and Ownership Costs
As a plinking pistol the Firefly makes the most sense for new shooters, family range days, and inexpensive trigger practice. Twenty-two LR ammunition still costs far less per round than 9mm, though prices and availability move with the market. Spare 13-round Firefly magazines are worth buying early, and the zinc-alloy frame design rewards light lubrication and routine cleaning rather than hard, high-volume abuse.
State Laws and Ownership
Before you order, check your state and local rules. A 13-round magazine is over the limit in some states, and threaded barrels on semi-automatic pistols are restricted in places such as California, New York and New Jersey. Some states also require the model to appear on a handgun roster. Your receiving FFL can confirm what is legal where you live.
