  Handles like a Glock, grouping at 50 ft is in a 2" circle. Very well ballanced, comfortable grip.
Site very accurate, easy to adjust.
My Sig Mosquito (5/5) Feb 15, 2011 KetchupHammer CA
  My first gun, and so far I have put about 1700 rounds through it. CCI mini mags are the way to go for this gun. Tried a box of remingtom 333 and still have about 250 left as this gun doesn't like them at all.FTF, FTE etc. Did find a decent, cheaper alternative in Federal Champions(blue/black box). The bullet weight and muzz velocity (36gr/1260fps) are the same and I have had hardly any problems with them. Also came with one metal mag and one plastic(?). My model is a sport version and as such has the extension set screwed on the barrel. This seems like not such a good idea and does actually loosen up when firing but it does not seem to affect the accuracy or function of the gun at all. All in all a fun gun to shoot and I have brought my wife and 12 yr old daughter to shoot with me and it fits their hands very well. Lotsa fun or great for practice. sooner or later I will upgrade to something with a larger caliber and I'm thinking it will be a Sig.

  This .22 handles great and shoots even better, I have seen bad reviews of the Mosquito but I have feed it all types of ammo and with the light recoil spring it has not failed yet. Much better built than the P-22 walther, and yes I have an informed opinion, I have owned 4 P-22's and I wished I would have started with the Mosquito, decent ammo and a little cleaning and it wont fail you.

  I took possession of my Mosquito last week and took it to the range today for the first time. I've read all the reviews and the owners card about using CCI Mini-Mags for at least the first 500, but those rounds are about as easy to find as hens teeth. So, I broke in the action by cycling it at least 1,000 times, manually, then checking it over for any bits of metal that might have broken loose. There were a few really small pieces.
Performance at the range was good. This is the first 22 cal Semi auto I've shot in years. I had a brick of Remington 22 LR Golden Bullets to shoot. I had 2 misfires (reloading the round got it fired the second time), about 12 FE issues, and no FF issues at all. Accuracy was acceptable, hand held, at 10 yds. The stock sight printed all of my shots about 2 inches low at that range but replacing it was fairly simple and solved that problem. Overall, first impression, I'm very happy with my purchase. The DA trigger pull is not acceptable to me (not as smooth as I like it) but SA trigger pull was crisp if a little heavy for my tastes.
Mosquito a Great Shoot (4/5) Nov 24, 2008 Dale T. Pierce Niceville Fl US
  Since my P226 was too large for her hands, I bought the Mosquito for my wife to use at the range. After I received it I took it to the range for break in because I didn't want her to have any trouble with it. Before taking it to the range, I disassembled, cleaned, coated with CLP, and reassembled it. At the range, I put 100 rounds of CCI Stinger through it. Then switched to Federal Copper Coat (Wal-Mart). No feeding problems noted except with Remington (tried several types).
Mag loading is important. After putting 10 rounds into a mag, turn the mag so the rounds are nose-up, compress the spring about 1/8 of an inch and gently shake from top to bottom (a couple of times) and back to top (stop shaking with the rounds leaning toward the feed end). For some reason, the rounds will fall into place for optimum feeding. You can recognize whether you did it right because the nose of the first round is clearly above the magazine.
Perhaps it seems a bit finnicky, but not for a 22LR. Certainly no more so than my Browning Buckmark which needs the same magazine shake maneuver, and on which I had to dremmel the lower side fo the breech to get it to stop the feeder jams. Note: My Buckmark doesn't like Remington 22s either.

  No trouble out of it as long as I shoot copper plated rounds. Lead nosed ones don't like to work quite as well. But I've shot Federal and Remington bulk ammo and have had 3 that didn't eject. I've had it for about a week now, and I have put 1450 rounds through it with the three failure to ejects'. Broke it in with 400 rounds of CCI Mini Mag's and then switched to the bulk without a problem.

  I use the Mini Mags and Remington golden bullets and it runs great. I love it and also have a Ruger and Browning .22 .
the Mosquito is the size of my 229 Sig and a great warm up gun.
Great little gun (5/5) Nov 9, 2009 Carlos Tellechea miami fl US
  Just purchased a Sig Mosquito over the weekend and took it to the range after a good cleaning. Misfired several cartridges, I took it apart and put in the optional spring it came with, shot three hundred rounds without another problem. Changed the front sight and I was shooting a nice group @ 10 yards. Sure would have liked it to come with another clip!

  I have read on the net all of the supposed problems with the mosquito. I noticed the following comments: bought the pistol and went directly to the range without cleaning first ( and you wonder why it is a 'jamomatic'!) and the famous "I have never had one but..." so, why are you even commenting?

I read the owners manual first, then disassembled and cleaned the pistol per the owners manual, use only high-quality, high-velocity ammo ( owners manual does not mention any particular brand ), clean pistol after each use and so far I haven't had a lick of trouble. Is it a match quality firearm? No, but it is fun.
