Description
The GSG Firefly .22 LR 4.9in Threaded 13rd Tan is a no-nonsense rimfire pistol built for shooters who want trigger time without breaking the bank. Chambered in .22 LR with a 4.9-inch threaded barrel and a 13-round magazine, this tan semi-auto runs on the cheap and runs smooth. Whether you’re burning through bulk ammo at the range or training on fundamentals, this Firefly keeps the recoil low and the fun high. Per GSG specs, it ships with a 1/2×28 thread adapter so you can run a suppressor or compensator right out of the box.

Key Features
- Threaded 4.9-inch Barrel: Why it matters — you can mount a suppressor or compensator without a gunsmith, making this pistol perfect for quiet plinking or reduced muzzle rise.
- Adjustable Rear Sight: Why it matters — dial in your zero for windage and elevation, so your point of impact matches your point of aim every time.
- Serrated Slide: Why it matters — gives you a solid grip when racking the slide, even with sweaty or gloved hands.
- 13-Round Magazine: Why it matters — more rounds between reloads means more time on target and less downtime at the range.
- Tan Finish: Why it matters — matches your EDC or range gear aesthetic, plus it hides holster wear better than black.
Who It’s For
This GSG Firefly is for the budget-conscious shooter who still wants quality. If you’re an EDC carrier looking for an affordable trainer that mirrors your centerfire pistol’s controls, or a new shooter wanting to learn fundamentals without flinching, this .22 LR fits. It’s also a solid choice for backyard plinkers and suppressor enthusiasts who want a host gun that won’t drain their wallet.
Pros and Cons
- Pros: Low cost per round, threaded barrel included, adjustable sights, reliable with high-velocity ammo, lightweight for carry.
- Cons: Not match-grade accuracy out of the box — expect 2-3 inch groups at 25 yards. Also, the trigger has a bit of creep; it’s fine for training but not competition.

Frequently Asked Questions
Will the GSG Firefly cycle standard velocity .22 LR ammo?
It runs best with high-velocity .22 LR (like CCI Mini-Mags or Federal AutoMatch). Standard velocity may cause failure to eject or cycle, especially during the first 100 rounds. Once broken in, it’s more tolerant.
Does it come with a thread adapter?
Yes, per GSG specs, a 1/2×28 thread adapter is included in the box. You can attach most .22 LR suppressors or compensators directly.
Is the GSG Firefly reliable for training?
Yes, for the price point. After a 200-round break-in, we’ve seen consistent feeding and ejection with high-velocity ammo. It’s a great trainer for recoil management and sight alignment.
What holsters fit the GSG Firefly?
It fits most universal .22 LR holsters and some compact 1911-style holsters due to the similar profile. We recommend a soft nylon or adjustable Kydex holster for best retention.
