GSG FireFly 22 WMR Pistol 13+1 4.9" Threaded Barrel Picatinny Rail

The GSG FireFly 22 WMR delivers precision rimfire performance in a full-size platform designed for serious shooters. This pistol combines the affordability of .22 WMR ammunition with features typically found on centerfire handguns. The threaded barrel and integrated rail system expand versatility beyond basic plinking applications.

What Makes This Different

Unlike standard .22 LR pistols, the FireFly chambers the more powerful .22 Winchester Magnum Rimfire cartridge, delivering 30% more velocity and energy downrange. The aluminum construction provides durability while maintaining reasonable weight for extended shooting sessions. The serrated slide offers positive manipulation even with wet hands, addressing a common complaint with polymer-framed rimfire pistols.

Key Features

• 13+1 capacity magazine for extended shooting without frequent reloads
• 4.90-inch threaded barrel (1/2x28 TPI) ready for suppressors or compensators
• Black anodized aluminum frame and slide for corrosion resistance
• Integrated Picatinny rail accommodates lights, lasers, and accessories
• Textured grip panels provide secure handling in various conditions
• Serrated slide design ensures reliable cycling and manipulation
• Fixed sights with high-visibility front post for quick target acquisition

The .22 WMR chambering makes this pistol effective for small game hunting, pest control, and training applications where standard .22 LR lacks sufficient power. The threaded barrel accepts most rimfire suppressors, making it suitable for noise-sensitive environments. Accuracy remains consistent through the 4.90-inch barrel length, with most factory ammunition grouping under 2 inches at 25 yards from a rest.
