ATI GSG Firefly 4.9" .22lr Threaded Barrel Pistol, Black - GERG2210TFF

Negatives:
I had problems out of the box before I even left the FFL. The decocker wouldn't work or the safety. My FFL guy was like do you want me to send it back? He even volunteered to test fire it for me. I was having a very bad feeling overall. I wanted one of these because my best friend loaned me his Sig Mosquito and I was very impressed with it. I shoot about 200 rounds and only had 2 or 3 jams.

I shot Aquila Hv (copper plated 40gr round nose 1250fps) and had tons of FTF as well as a few FTE. After a while the FTF count went down to every other magazine.

I then tried Federal Champion hollow points (36gr copper plated 1260fps) and had again tons of FTF but almost no FTE. I noticed the nose of the bullet would tilt down causing this to happen.

At this point in time I'm ready to sell it. So, I put it away for a while, as you can imagine, until I had the courage to try it again. Upon trying again I added Blazer lead round nose to the mix 1235fps.

Almost all the problems I was having began to go away when I painfully was able to put 380 rounds through it. I never polished the feed ramp like so many have done. It shoots all 3 ammo brands very well even the 1235fps blazer now.

Positives:
Very accurate
Threaded barrel
Rail
Has the feel of a larger pistol

I polished the feed ramp, cleaned, lubed, etc and this thing will still choke (FTF, FTE) on HV bulk ammo. I have not tried minimags but hoping this will help with the issues. I got frustrated with this handgun so I move on to shooting some of my others. It is fun to shoot it suppressed, but it has been rare to cycle more than 3 rounds without some sort of failure.

My son and I both bought one of these pistols to plink with and have fun. Neither are able to cycle a single magazine without having a malfunction. Failures to feed and failures to extract being the most common. This continued even after changing the recoil spring and polishing the feed ramps. Buyer beware these pistols are complete junk. Take a few minutes to read honest reviews online about them and save yourself the money.

When I first received my GSG Firefly, the magazine would not lock in place easily - I had to wiggle it or smack the bottom of the mag hard in order for the mag to seat properly.
I reached out to customer support to arrange a return for repair. My customer support experience was not good and I felt I made a mistake by purchasing the pistol.
Before investing additional money to ship the pistol back, I decided to spend a little time looking over the problem and realized the bottom of left grip barely extended too far causing the interference. I polished a very small amount of material from the bottom of the grip and reinstalled. This resolved the issue with minimal effort.
Since then, I have fired hundreds of rounds through the pistol and have not experienced any problems - not a single jam or misfeed, which I think is exceptional for a 22LR pistol and bulk ammo.
So, in the end, I give a 4- star overall rating only because of the initial problem and poor customer support.
The Firefly has become one of my favorite 22 pistols to shoot and I recommend it. I have considered purchasing another because PSA is selling for a terrific price.

Great feel in your hand. Took this straight to the range and had a great time with this new firearm. Would purchase again.

Love it... Easy and cheap to shoot. Fits my hands perfect I'm 5'7 170lbs.

Very Good for sub $200 gun. Basically a mosquito clone. With polished feed ramp this gun will feed bulk ammo reliable.

Great 22 pistol, runs ammo like it can’t get enough, shot 500 rounds no problem even tho it looked like it was full of gunk

Jams all the time. Mine was shooting better with 36gr bullets and higher velocity. Other than that it shoots fine when it's not jammed

Love the gun. Needed to polish the feed ramp to run cheap bulk 22. Best price for a threaded barrel.

Dislike that it has the 'magazine must be in' safety "Feature". Trigger leaves a lot to be desired. Really accurate though and so far very reliable. For the price though, good value I feel.

It is a nice 22. I had to polish the feed ramp but I would say its reliable with the right ammo. I use cci mini mags

Great pistol for the price. Feels more like a larger caliber pistol. Have ran a few clips of Remington thunderbolt through without any problems. Love the double action, decocker, and the safety fits my thumb just right. I wish it came with two magazines, that would be my only complaint. Feels well made, two thumbs up GSG.

Gun works well but will jam if using lighter ammo

The trigger sucks...very hard trigger pull for a 22.

Performed very well straight from the box. The finish on the slide is not the best but with a little honey oil, i was able to clean it up a bit. It also doesn't come with a manual or take down guide. Overall really a good gun for the price.

Great little pistol at a good price. This is the a sig pistol before they discontinued the rim fire lineup. Be careful it does toss sparks out the top and can get in your eye.

I was anxious to get my hands on one of these Fireflies. I understand that GSG used to make the highly-respected Mosquito for SIG. In time, it may become a favorite for me or my wife. But I was disappointed in how stiff the controls and trigger were out of the box, even after lubrication. I'll try to post an update after adequate break-in.

I highly recommend seeing/holding one of these before buying it, especially if you love the way a full-size 226 or 229 fits your hand. This slightly-smaller-scale version feels, well, like someone shrunk a great gun until it no longer fits... my hands, at least. If you have smaller hands or shorter fingers, you may love it.

Great deal on this GSG and it was as good as I expected it to be. Thank you!
