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! | ||||

New Sig Mosquito (5/5) | Mar 17, 2014 | James West | Monroe GA US |

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. |

Mosquito (4/5) | Oct 27, 2009 | Brad | Natchez MS US |
| Finicky with most "underpowered bulk (rather not high velocity)" ammo, even with spring changes. seems to like HP ammo very well. with the three, included front sight pins and the take down ability, it's easy to choose which sight fits you the best. i can definitely shoot my 226 better b/c of this little bugger. BTW, it eats Remington Golden Bullets and CCI Mini Mags like candy. the only real Stinger problem, is the failure to extract "live" ammo, some of the time; it's only b/c they are longer than regular .22's and b/c of the heavy wax that is applied around the bullet | ||||

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. |

Puzzling (3/5) | Mar 11, 2013 | John Cassidy | Novi MI US |
| Have two Mosquitos, one for me and one for my daughter. Still in break-in period for both, trying all sorts of ammo. All high velocity or hyperV. So far, the Remington golden 40gr are the winners. Almost zero issues. For the heck of it, tried 2 clips of 40gr Thunderbolts yesterday. Expected problems, and not one misfire or ejection issue. CCI 36gr HP not perfect by any means. About one in ten don't eject or reload to the chamber properly. Got some CCI Velocitors coming next week. Maybe the 40gr bullet is key. Biggest problems? Surprising, but Winchester SuperX HyperV 40gr HP. Can't get three in a row to fire. Switching clips, alternating bullets, etc. in both guns to see what works best. These things are really a puzzle, but when they work they are really fun to shoot. | ||||

After 1st outing w Mosquito (3/5) | Mar 15, 2012 | Theresa Lamb | OLIVE BRANCH MS US |
| Love the feel, style etc of this weapon; wanted something for cheaper practice as my weapon of choice is my Glock 19. I did have some isuses with FTF, FTE using bulk .22LR Winchester. Will relubricate and I am going to get the CCI Mini Mags recommended & hope that clears up those issues. I called Wal-Mart sporting goods dept and they do carry the CCI brand and it's just a little more expensive than the Federal and Winchester 550 and 555 boxes. | ||||

Mosquito sport model (3/5) | Nov 25, 2008 | don felts | Orange Te US |
|
The first 100 rounds included several that did not fire on the first try, one unfired round that would not eject, and several occasions of the action not fully closiing. Accuracy was good. The manual is contradicted by a separate sheet regarding which recoil spring should be used. There are several errors in the manual. I have not tried the cci cartridges yet, nor the heavier spring that came with the gun but not in it. The weight on the end of the sport model barrel loosens during firing. Since the front sight is relocated to this weight on the sport model, I am amazed that the accuracy was good. I have moved the sight back to the position on the non-sport model. I am no gun expert, but I am amazed that Sig secured the weight on the reduced diameter of the barrel with a setscrew. I believe a little lump travels down the barrel every time a bullet is fired on any gun. Not smart to setscrew or clamp the barrel of any gun. |

Handles like a Glock, grouping at 50 ft is in a 2" circle. Very well ballanced, comfortable grip. Site very accurate, easy to adjust. |

Sig Mosquito (4/5) | Jun 27, 2010 | Roy Darrington | Sacramento CA US |

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. |

Don't fear the Mosquito (5/5) | May 6, 2009 | John Messer | Simpsonville SC US |
| I purchased a Mosquito a few weeks ago and have put about 350 rounds through it so far. I've had no problems except when I tried to use CCI Stingers, which it hated and ftf or fte about half the time. It loves Federal Gold Medal Premium and CCI Minimags. I clean after every firing and it's very easy to strip and clean. Very fun to shoot and glad I made the purchase | ||||
