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. |

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. | ||||

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

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. |

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. | ||||

Sig Mosquito (5/5) | Sep 5, 2009 | Jarred | Clearwater Fl US |
| 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. |

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. |
