I know there's been some threads about this in the past, but I want an up-to-date opinion.

The Sig Mosquito: what's the verdict on the reliability and durability of this gun?

Thanks

To keep things brief: the consensus is that it sucks. Poor reliability, crappy materials (can you say cast zinc?)...nothing like P2xx series Sigs.
 
My wife and I have been shooting one every weekend. If you use CCI Mini Mags only, it functions perfectly. Reliable and accurate. Very good grip size.

Only draw-back is the trigger pull. A little long on SA, and too heavy on DA.

Other than that, no complaints.

For combat style .22LR pistols (with full-sized slides), the material is either aluminum or zinc. Kimber .22 1911s use aluminum. Sig Mosquito uses Zinc. If you make it with steel, the recoil of .22LR is not powerful enough to push the heavy slide to complete the cycle.

This may be true (isn't CZ Cadet all steel though?), but I would much rather have aluminum alloy than zinc...Cast zinc used to be referred to as "pot metal" in the old days, as it is a very soft material that is not particularly fit for use in firearms. I'm glad yours is working well, but many others have reported problems with theirs. I remember seeing a picture on ar15.com of a slide that has basically separated into two parts.
 
I own a Sig Mosquito and a Walther P22. I'm going to post a whole head-to-head comparison between these two guns with lots of photos and whatnot, which will include photos of the guts of the guns, how they disassemble, clean, how they compare to each other in size, how they compare in size to other guns, etc. Look out for that sometime around next weekend (February 3) if you are considering buying one.

I can tell you right now that my reviews are not going to be negative. These guns are both FUN :D to shoot. There are always trade-offs with everything though. Both are "ammo picky" but they both perform very well with CCI Mini Mags. I have also used CCI Velocitor with good results. With these higher-end copper plated .22LR rounds (Mini-mag: 7 cents each, Velocitor: 10 cents each - whereas a normal lead .22LR round is more like 3 cents each) you will get about the same reliability as your average 9mm autoloader... maybe 1 hiccup of some kind every 200 rounds - very minimal. Regular cheap ammo like Remington Thunderbolt, Remington Game Loads, CCI Blazer, CCI Standard Velocity, American Eagle/Federal.... you will experience some problems with these rounds, but I still shoot these cheap rounds and have lots of fun with these guns.

Another thing with these guns is that they dirty-up in a way that is just WAY beyond what you are going to get with your average 9mm, .40S&W, etc. The .22LR ammo is very, very dirty and you have to spend a lot more time cleaning the gun and making sure it isn't turning into a gunpowder caked mess of blackness. Personally I love cleaning my guns, so this is not a problem in my book, but if you like to keep it simple and not really clean, buy a Glock in 9mm and it will work out a lot better for you.

Both guns have fixed barrels so they are inherently accurate, but neither is as accurate some of the .22LR guns from Ruger, Browning, etc. where both the gun and the barrel is much bigger and heavier and there are fewer moving parts and the parts that do move, move less. Both the Walther and the Sig use a skinny barrel with a barrel sleave outside of that, which makes it look like something a little smaller than a 9mm barrel but is not (I'll post some good pics of this).

The P22 is supposed to be 75% the size of a P99. The Mosquito is 90% the size of a P226 - so it is much bigger. The P22 is a very small gun, but that is part of it's charm for me. The Mosquito is also much heavier than the P22.

Anyway, I'll have more to say later. Mosquito is a cool gun. Just clean it right, use Mini-mags and don't expect it to be a bull barrel target pistol.

If you look at the CZ Cadet carefully, you will see that only a small part of its slide blows back during the firing cycle. None of the .22LR cartridges has the power to blow back a full sized steel slide.

This is also why all the steel material .22LR pistols have that different look from their bigger brothers.

Sig Mosquito has a fine balance between the combat pistol look & .22LR functioning. It is also a $500 pistol, so I don't expect that it is made of titanium or other expensive light weight metal. It works fine for me now.

My Mosquito has been sitting at FN SPorts in Montreal (the Canadian Distributor) awaiting warranty work since July:mad: :mad: . They can't get parts:mad: :mad: :mad: :mad: :mad: . I did get it back last week and hopefully it has been repaired but I haven't had time to get to the range to test it.

So folks, consider parts availablity as part of your decision to buy. I have a P220 Tactical and there is a world of difference in fit, finish and reliability between these two guns considering that there both SIG. And yes I know one is $1500 and the other $500, but SIG's reputation is now suspect.
 
I’m one of those guys who don’t own what he’s commenting on so take my post with a grain of salt.

That being said, when I wanted to purchase one (SIG Mosquito) and had already obtained authorization to do so from the boss (my wife); I did tones of homework.

I visited every board I could that had any comments about them, and also made inquiries to owners of them.

I had a few people tell me to buy one with confidence because, though they are finicky, they can be made to work.

The majority of the owners told me to STAY AWAY!

The common opinion of SIG Mosquito owners, who posted their opinion on boards or who responded to my inquiries, where that they are unreliable, ammo sensitive, and are prone to breakage with little or no support from the manufacturer, coupled with long repair turn around times.

One SIG Mosquito owner told me I should buy it for the number of “stoppage drills” the pistol would invariably provide me with – NO THANKS!

THE FOLLOWING IS OPINION:
_______________________________________________
Often the gun board opinions can be misleading since owners who post are statistically more likely to have a problem with them, and as such are more likely to post inquiries as to how they can make “it” work reliably.
________________________________________________

Such as I did with my Ruger P345; if it had performed flawlessly I never would have joined the Ruger forum to find out how to fix it. In my opinion however, my Ruger P345 is a very good pistol and now performs flawlessly, but my Ruger Forum post of: “how do I fix this heap of junk” remains suspended in internet ether for all eternity.

Conclusion: the feedback on this pistol was negative enough to defer my buying it.

As said by a prominent (and in my opinion “expert”) retailer of high quality firearms (I’m sure this would be a miss-quote so I’ll put it in my own words): SIG ARMS is not the same as SIG, is not the same as SWISS ARMS. – nuf’ said.

EDIT TO ADD: if they could put the guts of a Ruger 22/45 or MKII into a SIG frame - I'd pay handsomely for such a 22. pistol.

A question to all those who responed to the original question of quality with a negative response, how old are your guns/info?

I just got a new Mosquito a couple weeks ago. At first I was kind of put off the gun by all the internet slamming I read, but sprinkled throughout the hate were comments stating that Sig had fixed some of the bugs that used to plague the gun. After talking to a couple gun shops I made up my own mind to buy one.

I went to the range last week and put nearly 500 rounds through it. I was trying a whole bunch of different kinds of ammo inorder to find out what worked best. Yes, there were a ton of FTF/FTE's, but only with the ammo that I had determined weren't the best for my gun. With Mini Mags and Velocitors the gun functioned nearly flawlessly. I guess I lucked out and got one of the newer generation guns.

If it turned out that the gun I bought was a piece of sh!t, it would have been my fault for not heeding the advice of the majority. I'm glad I didn't, I love this little pistola.

YMMV
 
My pistol was purchased new in April of last year. Have not managed to get through a mag without several jams. That being said I also have not tried Mini-Mags in it, I have a 1000 sitting here awaiting a decently warm day without wind to try them out. If they do not work I am going to have to send it back to the morons at FN Sports...
 
i don't think you'll find any thread on this pistol that will give you that warm touchy feeling to buy one with confidence,or not to buy for that matter.

a previuos post really hit on a good point in stating that this gun needs to be clean to function well,and that your choice of ammo will either give you pleasurable plinking or a frustrating day out.

i really like mine by the way for the reasons that i wanted something that was full size,or close to,felt good in my hands and resembled a combat pistol.

i've already stated my dislikes in a couple of posts, so i won't bore everyone by constantly repeating myself. at least use mini mags for the first 500 rounds.
 
A bit of an update: Took it to the range with 200 Mini-Mags and it worked flawlessly. I picked up another 3300 rounds of the mini-mags. Its good that the pistol works but I would not mind it working with another brand of ammo though, but hey, at least I don't have to send it back to FN Sport!
 
I still can not understand why everybody is referring to these guns as Sig Arms? Mine says Sig Sauer, Made In Germany. If the Americans are stuck with an inferior copy what does that have to do with my gun?

Mine has worked very well considering I am using the cheapest ammo I can find that still has a copper plated bullet. Yes I have had a few jams but I have never even bothered to try high quality rimfire ammo. I am sure the very few jams that I have had were caused by cheap and inconsistant ammo. I have never bothered to even change out the slide spring to the lighter one.

The only other thing that bothers me is the almost unusable double-action trigger pull.
