I may have convinced my younger sister that she wants a .22lr pistol for her graduation present (fingers crossed).

Right now she is looking at the Sig Mosquito.

I know that for less money there are superior handguns available, but they don't appeal to her for whatever reason so I'm taking this as far as I can, however I can. It's better to have her shooting something that is finicky then nothing at all in my mind. I've read that many of the CCI brands work flawlessly but bulk American Eagle (far more affordable) requires some tuning of the handgun to get it running properly. Can anyone second this? What do you use in yours?
 
Heres my old thread on the Mosquito and the P22:

http://www.canadiangunnutz.com/forum/showthread.php?t=132068&highlight=SIG+Mosquito+P22

Unfortuantely, I don't believe you can really "tune" the gun to accept the cheap ammo. It will work "o.k." with cheap ammo, but you will be clearing malfunctions regularly. CCI Mini-mag is the ammo. CCI standard velocity is a good secondary (and cost effective) alternative. You might get lucky with the odd brand/batch of cheaper ammo, but don't count on it.

American Eagle is not a good ammo for this gun. Something like those "Federal Champion" boxes might be better. I'm hesitant to make declarative statements about what will or won't work with this gun, as mileage does really seem to vary quite a bit.

My gun range buddy shoots his regularly when we go, and I have to say I am a little dissappointed in its performance. I wont go so far as to call it a "jam-o-matic", but if it doesn't have the ammo it likes, he rarely gets through a full 10 round mag before a misfeed.
The sigs come with 2 different strength recoil springs. The CCI Minimag use the heavier spring, and he recently installed the lighter spring. It did make using other brands somewhat more reliable, but I honestly couldn't be bothered to buy a gun that is that finicky with ammo. CCI Minimag ammo is a lot more expensive, and not always available (at least where I live) due to the fact that its usually cleaned out of the cabinets at every retailer quickly.
I think your sister could do better with a more reliable gun for a first handgun. Nothing turns off new shooters more quickly than an unreliable first plinker.
I AM ONLY STATING MY PERSONAL EXPERIENCE WITH THE SIG MOSQUITO.
I am sure the are owners out there that will extoll their virtues, but, the sig my friend owns was brand new when he bought it, and he is VERY vigilant about cleaning thoroughly after each shoot. He has conceded that he probably made a mistake buying it before getting real world feedback on just how picky it is to shoot.

Anyone considering Sig Mosquito should know that the gun has a pot metal (zinc) slide. That alone is reason enough to avoid it IMO. Pot metal has no place in firearms.
 
Like I said Jay. Convince her to get a Ruger 2245 Mk2, Its gonna be much better, reliable, Easier to get parts and cheaper and gonna have a much better rep and resale value.
 
My mosquito is great. I'm kind of regretting selling it considering the cost of ammo these days.

It is touchy with ammo, no doubt about that. Mine loves CCI Minimags and eats them no problem. Everything else is touch and go.

IMO - the pot metal slide isn't a big deal. It is after all, only a .22. I've never had a problem with mine, but it only had minimal rounds through it.
 
Never shot the Mosquito but my Browning Buckmark, when I still had it, shot everything I fed it, no FTF or FTEs.

Last week some guy at the club, Burlington Rifle & Revolver Club, gave me 4 boxes of his .22lr ammo (AE & Federal HPs) because they wouldn't stop jamming in his newly purchased Ruger MKIII. I thanked him and gave him a box of Remington YellowJackets to tryout, they jammed in his Ruger too.
 
The last two range trips resulted in no more than one jam in my Mosquito. But I've taken to only using MiniMags.

Looks the part, but it's finicky.

That's sort of like saying "I've never had problems with my car, but I only have 2,000 miles on the odometer". Do a google search for cracked Mosquito slides and you will see why pot metal is a bad idea.
 
I've been pushing a Ruger Mk II or a Browning Buchmark but she isn't interested in either of those, it doesn't make sense from a reliability stand point but I think yaya was right when he said that the Sig Mosquito "looks the part".

The review of the Mosquito that I read mentioned applying the factory supplied lube as well as cutting a full revolution off the weaker spring to achieve reliable function with American Eagle ammo.

I'm checking out your thread right now ghostie.

Well, I took the 5 minutes out of my life to follow your advise and I found nothing about cracked mosquito slides. I think it's time for you to start busting out the links to back this claim up, seeing as how you found threads about cracked Mosquitos so readily available.

I searched for:
Mosquito slide cracks
Sig Mosquito Slide
and Sig Mosquito slide problems.

I think you are thinking about a P22, the Walter variety. The P22 and Mosquito are very different. I know that Ghostie had a problem with his slide of the P22 - he also had something like 20K rounds through it to.

IMO, its not worth worrying about because the chances of it happening are slim. Granted, it is still pot metal, but you know what? I don't care.

I never had a problem with mine in regards to the slide. Ammo was a different story.

My Walther had at least 35,000 rounds through it, but the real problem (in hindsight) was the use of CCI Stingers. CCI Stingers might be o.k. used in moderation and especially with a stiffer recoil spring, but I did neither of those and the gun blew apart in less than two years.

I also blasted through lots of Mini-mag, Velocitor, Yellow Jacket, those CCI segmented things that have the longer case like a Stinger, and just about every other kind of ammo you can imagine.... yah, it doesn't work long term.

For SIG, I'm not so sure that durability is a major problem with them. They seem to be more solid than the P22. I know that the slide on the Mosquito (the blue slide anyway) scratches very easily, if that is an issue for anyone.

I think the main issue with the Mosquito is the reliability/ammo-picky issue. It can get frustrating - especially if you are used to shooting centre-fire handguns (like SIGs) that never have any issues.

A secondary issue with the Mosquito is the trigger... it's not really my (or anyones) ideal rimfire pistol trigger. It's o.k., but even the P22 is quite a bit better.

I hope we can get some P220/P226 conversion kits soon. I don't think we wil see the P229 kits :)() but what can we do.

P.S. - targettarget... I never responded to your invitation to try the P229 Elite. Definitely I would love to... but I am in Vancouver. I'm probably going to get one for myself soon... I'd still like to find a way to get a Stainless Elite (229, that is). Time will tell.

Sorry to hear about your 5 minutes.

There used to be a huge thread on the Ar-15 board that contained pics of several cracked mosquito slides. The thread must have expired, as I can no longer find it.

From what I gleaned on sigforum, the conversion kit appears to be ammo sensitive as well and - surprise, surprise - works best with CCI mini mags. If you want a quality .22, I would suggest that you stay away from guns that were designed to imitate the look of centerfire pistols and buy something that was specifically engineered to fire rimfire ammunition reliably.

Putting a full-size slide on a .22 cal pistol is sort of like putting square wheels on a car - a very poor choice from the engineering perspective. If you make the slide out of steel, it simply won't cycle because .22 ammo does not have enough oomph. If you make it put of a lighter material like aluminum or (god forbid) zinc, it might cycle but will only do so reliably with hotter ammo like CCI minimags. Of course, feeding a steady diet of hot ammo to a pot-metal gun is not gonna do wonders for long-term durability.

There's a reason why most good rimfire guns look the way they do.

Yah, I think this is probably very true.

My girlfriend used to have a Ruger 22/45, and we shot it quite a lot. To me, it was always a bit boring though. The P22 (Rest in Peace) was actually a lot of fun. I could fire 10 rounds in under 2 seconds - sometimes I think I must have been getting close to one second. It was a blast to shoot. I shot through a whole 525 round bulk pack of federal "Champion" in one afternoon a bunch of times - and it never really got boring. That gun was great for the two years we had it. Yes, it developed that problem where hand cycling would not lock the hammer back 100% of the time (in hindsight we now know that this was because the slide was developing some kind of micro cracking or stress) but that didn't occur until about a year and a half into about a 500 rounds per week existence. I actually miss that little gun, but I don't think I will get another one. I want to find something else.

I sold my Mosquito in the EE. I see that the guy who bought it has since sold it again. They are o.k., but Mini-mag is sort of half to a third the price of 9mm, whereas it is more like a fifth of the fun of a 9mm - in my opinion anyway. Cheap .22 ammo is more like a 9th or 10th the cost of a 9mm round.

I'm still looking to find a good .22 semi-auto pistol. I don't even know what I would recommend anymore. The SIG conversions look interesting. My girlfriend uses a Beretta 92 Ciener conversion on an old VPD surplus Beretta frame full-time (the slide on the original surplus VPD gun eventually cracked and we sold it off as scrap ... check my posts if interested in the story). That is actually a really nice reliable .22!!! It weighs a ton compared to other .22's but it works great. Those Ciener kits seem really good, but I think they only make a few different models... GLOCK, 1911, Beretta and maybe a few others.

The same names always come up in this debate. The Buckmark and Ruger pistols don't really do it for me, and I've certainly had my fill on the Rugers anyway. That S&W auto and the Beretta Neos look like something out of bad 70's sci-fi. The CZ Kadet seems o.k.. Buy another GLOCK (I sold the 17 I used to have) and get an Advantage Arms kit? That Beretta 87 target pistol? Seems like it could be fun, but sort of reminds me of Robocop's gun.

Sometime I think the right thing to do with .22LR is just get a revolver, like one of those new 5 inch model 63's they have now, or the 617, or a Single Six if you like that kind of thing. I think that the "real" .22-type ammo for auto-pistols is the .25ACP... but we all know that we can't be trusted with such things. The rimmed .22LR cartridge itself seems to be a bit of a square peg to the auto loading pistol's round hole.

I was trying this guy's .25 at the range awhile back. For a guy like me who never owned any handguns until well into the "Brave New Post '95 World", just the look of those small centre-fire rounds is so cool.

Maybe buying a $150 Tokarev and a crate of corrosive ammo is the way to go. I've mostly just been shooting 9mm since January of this year (Mosquito was sold and P22 died at about the same time), but now - with tax - I am paying 30 cents a round for 9mm. Each mag is 3 bucks. Each trip to the range is about $75. If I go every weekend (which I do) that is $3,900 for 2 to 2.5 hours of shooting a week. I can afford it no doubt, but it would be nice to find a cheap blaster to blast off 500 rounds like my old P22. The whole thing is a bit of a conundrum.

I wanted a SIG Mosquito because it looked so damned cool compared to the other commonly available .22 semi pistols, but after doing some research, I quickly changed my mind. It's apparently pretty ####ty.

Ruger 22/45 is quite possibly the cheapest handgun out there, with the exception of a few Norincos. At that price, you can't really expect top quality. Don't get me wrong, they are not terrible guns, but you can do much better if you're willing to spend a little more.

If you want a top quality, reliable, match-grade accurate .22 semi-auto, I would recommend S&W Model 41. The new ones are made by S&W's custom shop and are a bit pricey ($1200) but you can buy a used regular production model for $600-800. High Standard is another excellent choice, but you'd have to look for a used one as they no longer make .22s.
