2 Friends I shoot with have Sig Mosquitos, and neither one of them can get through a mag of ammo without a FTF or FTE. Both are running the light spring, guns are oiled up, still nothing but problems. I cut a few coils off the light spring, and got one of them running on Rem 550 bulk, but Win Super X Hyper velocity, still wont cycle the slide reliably. Maybe junk ammo? can't imagine what the heavy spring is for, when CCI mini mags won't cycle the light one. Makes me happy that I have a 22/45, at least that gun could be fixed with a Volquartsen extractor. What gives on these mico Sigs??
Anybody happy with their Mosquito?

The one my buddy has works 100% flawless only with CCI MiniMags. Also, the trigger pull, in both DA and SA, stinks. Not a typical Sig trigger at all.
Just my .02,

I have an early one, and mine has run on just about everything I put in it. The only type it really didnt like was Federal "Target", but a couple of other .22's Ive owned didnt like them either.
Mine came with the "white" spring installed, and thats what i use. Mostly, I use Winchester Super X (old stock, not "hyper" stuff), and its always worked well.
I've had a number of Rugers, as well as quite a few others, and the Mosquito, and the P22 have been more fun, or at least mine have been.

I have one. Tried everything around the same velocity as the mini mags with no luck. It's getting better as the round count goes up. Saw some tips on youtube about polishing the ramp and such. Don't have a link.
For what it is and how it feels, I'm satisfied. It can be very accurate once you get used to the 1/4 mile gaps between the rear notch and front sight during allignment.
Lots of oil, keep it clean, don't expect to run like a glock, shoot alot - good luck. You have to admit though, it a hell of alot of fun!

First mosquito flawless with cci minimag, all other ammo, problems. This was with the white spring. After around 10,000 rounds, stress fractures developed on the slide on each side. Sig replaced the gun, sent two springs, both identical, both heavier looking. Functions flawless with cci minimags, won't even attempt other ammo. The newer gun appears to have much tighter tolerances. If I was to buy another 22, I would buy a ruger, like I recommended to two friends.

Very unhappy with my Mosquito, Only Jams on two rounds out of every magazine with CCI mini mag. Tried both springs, same problem with several other brands of shells. Soon to be sold.

I've had my Skeeter for a couple months now. One of the nice things about the Mosquito is how similar in size and appearance it is to a service caliber weapon. This gives it an edge if the gun is being used to acclimate a new shooter who is getting ready to make the jump to a regular weapon. It has a decocker, slide stop and safety in all the right places.
I thought mine would be ammo sensitive after reading all the things you see on the net. It wasn't. I had a box of the cheap Federal stuff from Walmart and thought I'd give it a try to get started. I was surprised at how reliable it was. Yes, I get the occasional FTF or whatever occasionally but I am using cheap bulk ammo. Everybody recommends CCI mini mags and I'm guessing the gun would be almost perfect with the quality ammo.
The bottom line with the Mosquito IMO is the fun factor. It's surprisingly accurate. Busting cans and bottles couldn't be more fun.

I really like mine. I have had it about three years. It ran 100% out of the box on CCI Mini Mags. After about a thousand of those, I changed over to the white spring. It now runs about 98% on the thousands of rounds I have shot from Federal Bulk Packs, and I am happy with that.

I really like mine. I did the break in with min-mags and had no issues. Mine is run almost all the time with a suppressor. While suppressed, it will run Remington subsonics with no problems.
Yes. Feed it nothing but CCI MiniMags the first few hundrd rounds. Then played around with some different ammo till I found some it likes. I've gone through 400 round range sessions with it and with ammo it likes it is accurate and goes bang everytime. Same with a buddy who has one. Like the Walther P22 and lots of other .22's it is picky about the ammo it likes. Like I said use MiniMags for th first few hundred rounds. Keep it well lubed and cleaned and you have a neat practice gun. I often carry a P229R 9mm. it's a great understudy for the bigger Sigs. If you want something that will feed nearly anything I would suggest a Ruger MK II or 22/45. Mine will feed and shoot about anything.
But the Rugers I use as target/plinking/hunting guns. And they are great. Have not heard such great things about the MK III's though. But like I said my Mosquito is my Sig understudy. Just like my M&P .22 is an understudy for my Bushy.

Mine works fine with CCI and Remington Jellow Jacket.
I like it because it's cheap and works with cheap ammo (comparing to 9mm) while almost exactly the same size, weight, feel of a service pistol (compared to walther p22, wich is more like a toy).
For those who say it's not like a real sig: hey what did your expect (at 1/3 of the price).

I've given up trying other ammo and therefore a happy owner. Just feed it Mini Mags and it's virtually flawless and very nice looking to boot.
As I was shooting away flawlessly with my Browning Buckmark yesterday, the poor fella next to me was clearing jams in the Mosquito he was using. To make matters worse for him, he was shooting a pink Mosquito. Told me several times that it was his wife's gun and that he grabbed the wrong box on the way to the range. Yeah, sure

Love mine, the owners guide states to use the mini mags, not a single issue when using them. I did not want a target gun, just something that emulated my other Sig's that we could shoot cheaply. I really like the Ruger Maerk series, just cleaning them is a bear, and no longer own one. The mosquito is simple so it gets cleaned after every use, a touch of grease on the feed ramp is not a bad idea...............
