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.
Two Tone fun gun (5/5)	Mar 13, 2007	Joe Dado	Latrobe PA US
I recently purchased the two tone mosquito. Unlike some other buyers, my version had no problems feeding CCI mini-mags and Remington Goldens. Trigger has some creep, but I already have a High Standard Victor for target and was looking for a plinker. I found it with the mosquito and am glad I chose it over the Walther 220, which I found a bit on small side for my liking.
New Owner (5/5)	Oct 20, 2006	Jim	Pletcher
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 (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.
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.

I went to buy a walter p-22 but then saw the sig and compared them side to side and the sig won out.more substancial,better grip and same price.
Mosquito Sport (5/5)	Mar 18, 2009	Eddie Daniel	tallassee al US
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.
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.
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.
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!
