GSG Firefly 22lr Pistol Review 

I purchased a used Firefly, and it would only fire one round and would not eject. I contacted American Tactical, who is the North American distributor. They told me to ship them the gun. They replaced the barrel, extractor, guide rod and spring, for free. The Firefly has a lifetime warranty. It runs great. You have to use CCI Mini Mags or similar good ammo.

I purchased a sig mosquito for my wife years ago. It ran flawless with cci mini mags. Forget running cheap bulk unless you want to practice stoppage drills

I just purchased a old school Sig Mosquito sport, and it runs perfect,as long as you use High velocity ammo. Will fire and eject standard ammo, but if you want it to feed,stick with High velocity,as recommended from GSG.

I bought one of these several years ago after GSG stopped making the sig. I believe it was the mosquito. It came with 2 recoil springs. 1 light spring for no suppressor and 1 heavy for suppressor. It also came with 2 mags. 1 black sig mag and 1 raw GSG mag.

To be honest, I'd go back to the standard magazine follower and see how it functions. But on almost every .22LR I have, throwing a suppressor on such a firearm does 3 things: it makes the firearm get dirtier far quicker; it's much quieter; and well, it almost always makes it run better, despite being dirtier. The last is because there is increased backpressure helps it cycle better. But the ammo I would choose for testing would likely be CCI Standard Velocity, which is my "standard".. If that does not work, so good CCI mini-mags.. if neither is worth a darn, I'd find a place to get rid of the firearm; don't need an unreliable firearm. I'd either sell it or give it away. And yes, I have given away a couple.. The most unreliable, I'd sell back to where I bought it ; let it be their problem again. I hate decockers as well. I feel safer just clearing the firearm; I don't trust safeties either; while I will use it if it's there, we all know that it's mechanical in nature, and thus can give one a false sense of security. The best safety you have is between one's ears.

I have one and need to use high quality amo, otherwise it will either stove pipe or not feed. I changed the spring, which helped a little I also used a spray lubricant on the magazine after loading the magazine and had better results.

I have always been a revolver guy. I purchased the firefly about a year ago. I have never taken it apart. while shooting it for the first time I noticed that the mag would come loose. I rarely shoot this gun, however now I have the mag falling out after I fire it. I have also noticed that I can pull on the mag and it will come out without hit hitting the release button. Any suggestions on how to fit this ? ( and yes, I have tried other mags. )

My experience with this is very similar. I found with quality rounds I have no feed issues. Cheap range rounds just hang up

I had the GSG MP5 knockoff a few years back. Very similar issues. It would eject the round load the next one but not recock the hammer. It would nose dive and fail to feed alot. After messing with it for a few months i sold it a friend and let him take over the headache He did some more work, it still doesn't run

I picked up one of these new at a gun show a few years back, paid about $250 for it I believe... 🤔 I rly enjoy it. I was looking for a cheap semi plinker in 22 and it def serves it's purpose, very fun little pistol. Yeah, it's no high quality piece, but it feels like it's made quality enough. Mine is very reliable too, I've put thousands of bulk through it over the years. Accurate , fun little gun and it runs great. So I can't complain 👍 I hate that you got a lemon man. Hopefully you can get something figured out and it'll start feeding better for you. Great video, thanks for sharing.

I have a GSG, I put a performance enhancement kit in it, swapped the trigger with my old colt trigger. I seriously love the thing. Great to carry in the field. But it does require high grade ammo. It's not a firefly, older one, 1911

I don't know if the pistol is any different from years ago, but a friend of mine had one, and it was nothing but a jam-o-matic. I have the TX-22 and although the rear sight leaves little to be desired, it has run flawless with any ammo I have run through it. 22 rf semi autos can just be hit or miss sometimes.

Hey BC, I challenge you to show us a suppressor that would make a .22LR make that sweet " PFFFT " sound that Q Branch made James Bond''s AR-7 sound like.

It seems most are not reliable. I heard the new ones come with 2 recoil spring assemblies, i wonder if this helps. I want one just because it reminds me of my 226. I might be lucky and get one that works. I have several 22 pistols that are ammo picky. One a Ruger,Walther, Bersa. It sucks that some just like certain ammo brands

Take the spring out of the mag and turn it around not upside down but around and the spring will push the backside of the round instead of the front

i have had ohe a couple years.the feed ramp and barrel are not one piece the barrel sticks up a little above the feed rsmp bevel the bottom of the chamber a little and that helps feeding also i see tou are using hollow points the donot feed well in most autos in my experence.

I have a gsg and it has never once jammed on me not even when it was new. it has been very reliable and alot of fun to shoot. I do not own a supressor so maybe that is what is causing your issue? I have seen suppresors cause a issue with gun malfunction when I was at the range but admittedly I know nothing about them.

The Mauser M20 (GSG Firefly and Sig Mosquito) is one of the trio that are basically the same gun. Magazines and other parts are interchangeable. The biggest difference was who was marketing the gun at the time as to which name it had on it. It does need the high velocity rounds to reliably cycle (1200 feet per second or above). It doesn't like cheap rounds.

Bellissima pistola molto précisa..

Sorry if I wasn’t listening to payed attention. But which exact adapter and suppresser do you have!

Sig made a pistol called the BAS which I have and I think it is nice , I don’t think it’s made now 226R 22 bas they had

The follower makes sure the round goes up properly and prevents bobbling

Fair review, Sig get rid off the mosquito, because even after all the upgrades reliability never appeared.

At the 10:00 mark, the good things, the bad things and the ugly things about the GSG FIREFLY 22LR.

I’m looking to buy another pistol, I have a Taurus Gx4 9mm pistol. I also have a mossberg 590 for home protection. Is a .22 good enough for personal protection? Or should I be looking into a higher caliber pistol? Can anyone point me in the right direction? My budget is up to $350

Don’t know if I’d beat on the back of a rim fire that was hanging up out of battery 😂 but I’m gonna pass on this one.

My CZ 52 decocker was 100% I used it and carried it "Cocked and Locked" alot as my Truck/Car gun.... Until I had the Trigger return spring replaced... After that it failed twice ... one time unexpected. I decocked it after a party I had went to and I was very "tipsy" fixing to sleep in my car in a pasture . I pointed it safely to decock and make safe... BANG... VERY EMBARRASING but everyone else was asleep Once to check again to make sure I hadn't hit trigger by accident when 100% sober ... BANG I DO trust my Beretta 92X decocker though. It actually rotates the firing pin out of reach

So… Sig gave their faulty Mosquito to GSG? Or other way???

There's a kit to change it to 14 rds

Basing your trust in decockers on the p38 is a bit disingenuous. Not all decockers are created equal. The Beretta 92 decocker is incredibly safe. The firing pin is held in place with a block that can only move up and out of the way with the trigger pull. The firing pin is also a 2 piece pin with the aft section built into the shaft of the decocker. So when you use the decocker the pin is rotated to the vertical and the dropping hammer can't hit it.

Twenty-second comment, ironic 😂

I was view 74 and Like 13. Practically FIRST..

misfeed issues already addressed. 2 springs come with it now and you need to be shooting 1200fps. maybe do another video using different ammo. mine shoots great!

U got to use hot ammo. Not cheap federal etc.i have one cycles 100% with cci 16fps ammo. Will not cycle sub sonic or 1000fps

I expected better from the country that produced the world's first operational jet fighter, and Rammstein.

You can’t shoot cheap 22 ammo has to be the good stuff

I did a video with this gun and today’s age this gun ain’t worth it. There’s so many better options out there that actually work and they hold more rounds in the magazines.

Ya i will stick with my TX-22 competition and that came with 3 mags

From my view the colors dont match exactly.

User error i believe.

I’m telling you 22s are finicky you need good ammo and it will not stick or double feed

In other words, it's garbage...

Mine is great with 40 grain solid tip it does not like 36 grain or less

Do you give file for follower ?
