Sig Mosquito for training


September 24, 2007, 10:50 PM
I am looking for a practice .22 semiauto pistol. I have a Sig 226 in .40SW and want to practice as much as possible without paying for the .40 ammo all the time.

What do people think about Sig Mosquito as a training pistol? Visually and upon a brief glance at the specs, it seems quite similar to the 226, but is it actually that similar, especially in the trigger area? Is it a good quality .22?

If it's not too similar to the real-caliber Sig, then there is no point in paying the Sig premium - I could go with a cheaper used .22 semiauto instead (what would you recommend?)

All opinions/tips are very welcome & appreciated.

I am very disappointed with the Sig Mosquito. For the price I expected better. Check on the forums, a lot of folks haven't been impressed.

A Walther P22 has its faults also but is lots cheaper than the Sig for the same basic accuracy and reliability.... and I *like* Sigs!!

$400 for the Mosquito could buy me a real 9mm.

The SIG Mosquito needs to be redesigned, as there are too many reported
problems arising from these firearms. If there is a "DUD" in the SIG line; the
Mosquito is it my friends. I don't [and probably never will own one], giving
the nod to the Browning BuckMark as my primary training pistol~! :scrutiny:;)

I have a fondness for the Ruger .22's, and my MKIII Target/Competition Slabside is more accurate than I am at 25 yards.

Two other 22/45 models round out the collection.

Both myself and my bride enjoy shooting these once the big boys go back into their cases.

Another contender to consider for inexpensive practice is a quality pneumatic air pistol.

Air pistols can be more difficult to master than a firearm, since the pellet remains in the barrel longer than it does in a firearm, but they do teach you "follow thru" and to hold those sights on target throughout the shot, and proper trigger finger control.

A small dot for a target, 20' away in the other corner of your garage, or out in the back yard, and you have a challenge on your hands.

One of the gun rags recommended a while back that if you send a few pellets a day "downrange" thru such a pistol, day after day and every day, you should see a marked improvement in your overall shooting ability.

I'll bear witness to the fact that it works. Daily practice at home.

The GAMO Compact target model retails for about $230.

I shot a friends Mosquito and it seemed very prone to feeding problems. I'm a Sig nut personally, but I don't think it's worthwhile to pay the brand premium on this particular piece.

I was watching a epeisode of The Shootong Gallery on the outdoor network and Michael Bane was shooting the sig .22 and it stovepiped right there on the first shot.But after it was edited it looked like it just emptied the mag.I had to rewind the dvr to make sure I saw what I thought I saw.I even got my wife to confirm.

Thanks, I'll be sure to stay away. I am sure I can find a good .22 for far less money, was hoping that this one would feel like my 226 though. But if it's a dud, I'll skip for now. Thanks again

I had nothing but problems with the Mosquito and sent it back and got a replacement and still was not impressed. Went and bought a Browning 22 and have been very happy. I love my other SIGS but the Mosquito was not up to standards for me. The Rugers have worked very well also for me.

I second the Ruger I have a MkII with about 3,000 rds through it with not one hiccup.

The guys at Sigforum talked me out of buying a Mosquito. Get a Buckmark or something and enjoy.
I wish somebody made a .22 conversion for P226...

I had a mosquito that would only shoot one type of ammo. Even ones that were rumored to work for others would not work in this gun. I sent it back to Sig and they took 6 months to get a new one sent out (yes, they sent a whole new gun). It still had the same problems and I cut my losses. I wouldn't recommend.

That's very disappointing to hear the mosquito has so many problems. I just ordered one and am really regretting my decision. I tried the P22 but is too small for my hand. The browning is not much to look at and I already have a Ruger. I purchased it to put an Outback II suppressor on it. I also chose it because it looks more like a standard pistol. Maybe I should reconsider and go a different direction.

I wouldn't regret it until you've tried it.
This is one where you definitely hear more about problems than praise.

I can add some praise. I have had mine for a bit over a year.
It is pretty accurate, I think more accurate than I am with handguns. I can reliably hit soda cans at 7-10 yards.
It doesn't like Federal 36g HP value packs. It feeds Federal Automatch packs, Remington GB (HP and solid), and CCI Mini Mags (HP and solid) flawlessly. I ran it over 9 or so months without one cleaning and over 2000 rounds before I started having FTEs. The only problems I had during that "torture test" were a couple bad GB primers. I cleaned it and I am back to 100%.

I can give praise as well. Functions exactly how it should. Any weapon with cheap ammo = problems, the mosquito is no different.

Accurate? You betcha!!!
