Handgun Reviews for Women, Part 2: the Sig Mosquito

Prepare to fall in love with almost everything about the Sig Mosquito.  Sig Sauer is my favorite gun manufacturer, second to none, so it was natural that I would begin longing for a Mosquito of my own.

I’ve used the Mosquito at the shooting range several times, and every time I start off loving it.  I love the ergonomic grip, the size and weight of it, and the fact that it’s a .22 and, usually, fun to shoot.  In many ways it’s the ideal. 22 pistol, and the fact that it’s a member of the Sig Sauer family is a huge plus.  But then it jams, and jams again, and I realize that maybe it’s not so perfect after all, which is a shame.

To be fair, part of the problem with the particular gun is that it’s a range loaner and doesn’t get cleaned on a regular basis.  However, “failure to feed”, FTF, has been an ongoing problem with this particular pistol, especially in the older models.  I tried using different types of ammo, and had better luck with CCI’s Velocitor .22 ammunition hollow points.  The guys at BulkAmmo sent me a couple of boxes to try out, and this particular ammo turned out to be a good match with the Mosquito (as well as the Walther P22 and Ruger III).  If you’re going to rely on a .22 for self-defense, don’t take chances with cheap ammo if you’re using this pistol.  You don’t want to risk a jam at a critical moment.

(I keep a couple of magazines loaded with CCI ammo for when I’m using a particular handgun for concealed carry, but when I’m at the range, I use cheap Walmart ammo for practice.)

One of the reasons for the popularity of the Mosquito is that it looks and feels like a “real” gun, or at least that’s what hardcore gun-nuts say!  It’s frame size is very close to the typical 9 mm or .40 caliber handgun.  It doesn’t feel like a toy, but then, as a Sig Sauer, I didn’t expect anything less.  In my experience, the slide, magazine ejector, and trigger are comfortable and easy to use.  Owners of the Mosquito report they were able to solve most or all of the FTF problems by, first, breaking in their new gun with 500-1000 rounds of CCI ammo.  Some owners claim their Mosquitos are now happy with any .22 LR ammo, even the cheap stuff.

The Mosquito weighs a comfortable 24.6 ounces, with magazine, and has a price tag of about $400.

If your purpose for choosing a .22 pistol is for cheap practice, there are less expensive choices that are just fine with cheap ammo.  If you want a handgun that has a solid feel and quality appearance, has the Sig Sauer brand name, and is good, most of the time, the Sig Mosquito is a good choice.

  1. I agree with everything you've said, Survival Mom. I too love my Sig Mosquito but dislike the high rate of jam when shooting. For that reason alone it's not my carry pistol and I wouldn't take it to a gun fight. However, I have, after talking to someone in the know, reduced jamming by 99%. I only use Mini-Mag .22 LR. It provides enough energy to cycle the slide, thus reducing the jam factor. So don't give up on this little gem, just baby it with the mini-mags. It's a great little plinker pistol.

  2. I have both a squiter and a walther. Hands down I love Walt, so much that I actually own 3! They are by far the top dog when it comes to 22 plinkers. I also enjoy carrying a walt when I don't want to print a big gun or try to hide a big gun. Everybody I have let shoot mine has said how much fun they are to shoot. Most have gone on to acquire there own. I've read your review of the walther and would agree with most everybody else that Walther P22'S ROCK!

  3. Any .22 semi-auto will jam if you do not use the right ammo. Sig recommends CCI mini-mags. I wonder if you used those? If so, did you still have a "jam" problem? Was it a failure to feed, or to extract? Have you taken the pistol apart and re-assembled it? A lot of guns get a bad rap due to improper ammo being used, or perhaps something as simple as putting it back together wrong after a cleaning, etc. Check this out: http://www.sigsauer.com/CustomerService/Faq.aspx
    Great site! Thank you for all you do

    • The one I\’ve been using is a range loaner, so I\’m not able to clean it or make any adjustments. I\’ve used it with 3 different types of ammo and still experienced some jams with CCI.

      • Are you holding it tightly? Sometimes lighter calibers cause us to have a relaxed grip. Recoil operated guns like a firm hand. Just a thought. My Ruger MKII likes plated bullets. Bullets without plating seem to catch on the edge of the chamber, digging in creating a jam.

  4. I am new to this group but i must take exception to the advice you gave about the sig 22 Caliber, Sig is a fine gun but the 22 Cal is not enough of what is needed to protect ones self. I am a NRA certified instructor and believe me that 22 will just piss an atacker off . You should carry nothing less than a 380 cal. you need enough bullet weight and penetration and bone crushing volosity to defend yourself . I recomend always carry as large a caliber as one can handle, and when I say handle I mean beeing able to shoot that caliber 20 to 50 tomes before it hurts your hand , or wrist because in an actual situation of defending yourself you will only shoot one , two, or three rounds .
    as for the jamming of your pistol it is perhaps the way you hold it , A semiautomatic must be held as far back into the hand as possible and as high in the hand as not to be in the way of the slide when it comes back that pistol needs something to recoil against , If you have a wimpy grip on the gun when it is fired it will NOT cycle properly it uses the energy normaly used to work the slide , to back the gun against the hand I must have the hand to recoil against..

    • I definitely do not have a wimpy grip on this gun or any other. If you do some research, you'll see that the Mosquito has a pretty long history of FTF. As far as advising people to carry a .22, I do no such thing, if you'll go back and re-read the article.

      • Enough with the stopping, knockdown power etc; A gun, especially a hand gun is only effective as the proficiency of the shooter. If the shooter is not comfortable with the size, weight, or the recoil of the weapon they will not want to carry it, nor will they train with it. My wife can shoot a 3" shot group at 50 feet with any hand gun but prefers the light weight and soft recoil of a .22. Years ago law enforcement all over the country were asked , of all calibers on the street which would you prefer not to be shot with, hands down it was the .22. Remember most self defense weapon use is done at a range of 15 feet or less, so a proficient shooter with a quality .22 hollow point can take care of business much better than an untrained hand cannon totter. Also a light grip on any gun has no impact on the internal workings of a gun, you can hold a weapon as tight as you want it still won't stop a miss feed or a jam. SurvivalMom, remember a good firm grip will help with sight alignment and the ability to squeeze the trigger. For those nay sayers on the virtue of the humble .22, next time your at the range let someone shoot you with a .22. I bet you will change your mind real quick.

    • Sir,
      As an Certified Instructor of 25+ years in over a dozen disciplines, I can assure you that your advice on the matter is incorrect. A .22 in the hands of a skilled and practiced shootist, is as effective as any caliber currently available for a handgun. 40 grain CCI Velocitors, or Aguila Interceptors, are both capable of penetrating to a depth which will exceed the .380 with everything but FMJ rounds. Here is an excellent article on the subject: http://www.dynamicforceinstitute.com/DFI_Dynamic_

      The .380, and everything larger are all excellent choices in a self defense encounter, but so is the .22LR in the hands of a skilled operator. The first rule of gun fighting is, bring a gun… If a .22 is all you have, or what you have chosen, and your skills meet, or exceed the standards for a trained operator, your chances of prevailing in an encounter will be every bit as good as someone with a larger caliber and no training.

  5. Try Remington Golden Bullets. I don't have a Mosquito, but I have a 22 barrel for my Sig P226. I found it does not feed well with most 22 brands. The Remingtons work great, no problems whatsoever. You can pick up a box of 500 at Walmart for $20

  6. I have just found your blog and I am enjoying it. I am gun nut myself and have owned and used the .22 pistols you have reviewed. I will give my opinion coming from own experience. The Walther works and works well. It is NOT the best gun for beginners because of the action. It is a Double Action Automatic which is overly complicated even for experienced shooters. The military Beretta has the same action and is loathed by our soldiers and Marines. Another option is a good used .22 revolver. These have several benefits. They are the least complicated to use, no magazines to lose, and good quality examples are quite affordable. I currently own an H&R and a Colt .22 among others. The older H&R revolvers are the "most bang for the buck", with some models as low as $100. I own more powerful, expensive carry guns, but None that are more reliable. Not to mention, that in some situations an un-complicated .22 revolver is the better choice to carry. I also own one of the more expensive North American Arms .22 Magnum revolvers. Again, this is sometimes the best gun depending on the situation. It is also the least compicated mechanism (single action revolver) and fires the more powerful .22 magnum. Keep up the good work.

  7. I just found this site. I have a Walther P22, it shoots just about anything, as long as you keep it really clean. I wish I could find a modern .22 pistol with the poly frame and grip angle, that has all the sharp edges rounded, that is as reliable as my Ruger MkI. It is heavier than I like my .22 pistols to be, it has sharp corners that cut and rub, and I really am not thrilled with the safety. But, the only time it ever jammed was when I got it caked with white powder sand.

  8. I just purchased the Sig Mosquito. I like the walther P22 as well. It is important for both pistols that you don’t shoot cheap ammo through them. You will find many blogs that say that the Sig jams, thats because of cheap ammo. Use CCi copper coated ammo or similar. I did a rapid fire of about 300 rounds of some cheap thunderbolt ammo and the lead actually melted to the inside of the barrel, it was a nightmare to clean it out. I then used CCI copper coated ammo as suggested and with the same 300 rounds there was no jam or lead in the barrel. Also, the sig comes with two springs, on for high velocity ammo and one for normal rounds, be sure to use the proper spring to prevent jams.

  9. Another Sig option is to buy a full size Sig 226 in 9mm or .40 and purchase the Sig .22 conversion kit. The .22 conversion kit consists of a barrel, slide and magazine that fits the 226 frame. Practice can be done cheaply with the .22 and then easily swapped for the larger caliber as desired.

  10. LOVE YOUR REVIEWS…….because of your experience with the Sig Mosquito decided to get the wife one. She has a Sig P-238 that she finds on the hard side to rack the slide. A Taurus PT 908 9mm that is also difficult for her to rack. She has a 38S revolver that she loves but is on the big side. The “skeeter” is as smooth as bore butter for her to rack, comfortable in her hand. FTF etc issues with 22s are common and most go away after the weapon is broken in and you find the ammo that firearm prefers. I have found AMSCOR Hi-Vol works as well as CCI at $25.00 a brick. It is 38 gr copper HP.
    Anyway……keep your reviews coming…..

  11. Hi Survival Mom,
    we LOVE the Sig Mosquito – they are PERFECT for my wife and daughter.
    The problem I have seen with other 22 handguns, is the size… the Walther is good, but very small – so if you have very small feminine hands, it would be OK. I think S&W makes a M&P22 – but I haven’t shot it, and Ruger makes a nice 22 pistol as well.. but I haven’t shot either of those. One other option is the ISSC 22 which is exactly like a Glock ( I have shot one of these at a range and had similar FTF issues with them.

    The ONLY ammo we have found to reliably and consistently fix the FTF issue is the Aguila Interceptor 40grain .22.. the reason for this is the higher muzzle velocity ( AI is a ripping 1470 fps) which is significantly faster than any other .22 ammo out there. This increases velocity has the power to cycle the slide and function flawlessly.

    We have put at least 2000 rounds through without a single FTF, stovepipe or other ammo related issue. Of those 2000 rounds, only 2 misfires, both from just ‘dud’ ammo ( which is about the same ‘dud’ ratio that Ive seen with other .22 ammo).

    The Aguila is a bit more expensive, but its worth it when it counts.
    The other thing about the Aguila, because its a “hotter round”, it makes a bit more noise and pop… making it sound much more intense than a regular 22 – good in case someone else is around, and thinking maybe you are armed a bit more than a “little plinker”.

    Hope this helps everyone…. the Sig is a fantastic sidearm, easy to conceal and dependable when used with the Aguila Interceptor — i highly recommend it.

  12. If any given person can provide a decent argument for their personal choice of .22 for CCW then that’s usually enough for me. Some guns, like the NAA Mini-Revolvers are choice and I even helped a lady, who was a legally designated Little Person, to find herself a carry gun and she decided on the NAA Wasp, in the end – very sharp open carry rig she has for it too and it fits her hand like you or I would carry a regulation sized snub nose…

    Anyway, just remember that with smaller calibers you will likely have to fire multiple times, even though they can do more internal damage given the ricochet. Even if none of those shots go wide in the chaos and you land every single round from the mag or cylinder, it may well require all of them to put down a determined or doped-up threat. That doesn’t always look good to a liberal heavy jury who are likely un-educated in the realities of firearm physics.
    – They’ll likely just see that you emptied an entire handgun into a fellow citizen, criminal or not, despite the fact that you may well have had to do so, given the diminutive caliber.

    Remember this phrase:
    “Officer, I fired until he was no longer a threat, now I’d like to see a lawyer, please”

  13. Despite what was just stated ^ above ^ I still don’t typically recommend any .22 caliber handgun to a person looking for self-defense firepower. While something is always better than nothing and I refuse to be dismissive of anything, stopping power goes an incrementally longer and longer way with increasing caliber size and strength. Still, getting shot by any gun once is usually enough to stop an attacker in his tracks or even mid-air, in some cases – long story…

    Just ask yourself what sounds best to you from the following:
    * .22 cal., etc.
    1 bullet usually makes a single hole and rarely exits the body if not shot in an extremity, causing massive internal damage to a human body due to ricochets off the skeletal system, which can alter a bullet’s trajectory as much as three times before coming to rest. More people are killed by a .22s than any other round in the country, but that doesn’t mean it’s a great self defense round. Despite these factors, a .22 has very little stopping power and can’t be depended upon to make a charging opponent drop his own gun or stop swinging that crowbar in the heat of the moment. If you’re target is human, the best application for any .22 would be medium-to-sub long range. An assassin’s weapons are not the same as self defense weaponry, sorry…

    * .380 auto, 9mm, .38 (+P), etc.
    1 bullet may or may not make two holes in a human body given a variety of factors at self defense range, victims typically drop to their knees or at least take a few steps back to steady themselves immediately after impact

    * .357 mag., .40 cal., .45 cal., etc.
    1 bullet almost always makes 2 holes and can inflict large exit wounds, victim typically falls backwards from a standing position or tumbles to the ground while in motion

    * .410 shot shell
    like the .22, it’s not really designed for self-defense. The Judge revolver made it popular again, but prior to this it’s primary application was for pest control in “garden guns” The gauge itself improves the versatility of derringers, if you’re into that sort of thing, and the Winchester PDX shells are especially nasty, with a dozen metal BB’s and 3 slugs per shell – many gun stores refer to this cartridge as “the kitchen sink” but my wife simply refers to them as “PMS Rounds”
    It behooves anyone that might take a shine to this approach to understand that you are restricting your weapons effective distance to just beyond bad breath range and with each pull of the trigger you are responsible for every single bit of scatter shot that exits your barrel, which is too great a liability in my book. I typically only recommend these things for carjacker deterrent or those who demand the most dangerous form of “non-lethal” (usually) firepower.
    Also, don’t believe the sales hype, you can’t expect to send an attack flying off their feet with a single blast to the center mass either, that’s firmly restricted to the territory of big bore shotguns and large caliber rifles and only under very specific circumstances.

  14. As much as I love my current EDC, a Beretta .380, the first caliber I usually suggest for self-defense, if you were only to choose a single gun is .357 because you can practice with cheap .38 Special all day long and then carry .357 rounds to protect yourself. Now, of coarse that requires a beefy gun to handle the recoil which brings weight into the factor, but I’ve found a nice middle ground with Ruger’s 5-Shot SP-101 line of snub nose revolvers. They’re built like a tank, too. Nothing fragile in that design.
