Mosquito bite

[RECIT]

I purchased a Sig Mosquito from Acadamy late in 08 its the plane model all black with no can on the end. I bought it to leave at my parents house b/c they own a low of property and had nothing but a 12ga Mossberg. So they needed a varmit gun for snakes and opossums and things like that eating their chickens at night. Anyway...I bought the CCI ammo that Sig recommends and have had nothing but problems out of this Mosquito. I have tried some Remington ammo as well. It will FTfire about 20% of the time requiring a second pull from the DA trigger. Every other mag or so I will also get a FTfeed. That is not the end of the world but I was getting my Mom more comfortable with it and she got frustrated b/c it was not reliable at ALL. But she is intimidated by my 9mm and .45. She likes it when it goes bang, it is just not consistent about anything but messing up. Has anyone had this issue with their Mosquito or does anyone know of a fix. Its been cleaned and lubed and cleaned and lubed again and again. I thought it just needed some more break in rounds, but 500rds later its in the same shape. Very frustrating at best.

Do a search on the Sig forum and you may find some help. This gun has been problematic, but I thought most had the kinks worked out. Gray Guns has been doing some work towards improving the gun, but I do not know where they stand in that process.

that should take you to a reall good thread. I also started one (before I found this one), and became convinced to just keep the Ruger and forget about the "crosstraining" for my P239 with a Mosquito. I hope Sig will fix the darned things because I still want one.

I purchased a Sig Mosquito ... it was not reliable at ALL.

Yep, that's the Sig Mosquito. I sold mine a couple weeks after I got it. At least I sold it for the same price that I bought it. Walther P22 is the one you wanted.

As much as I love my P239, I just didn't have a good feeling about the Mosquito.

The sig mosquitos like CCi 22 ammo and states it in the instruction manual,It also comes with 2 recoil springs one for lregular loads and one for hotter ammo.I shot federal bulk box out of mine and got about 10% FTE from that ammo

Thanks for the links, most of the problems addressed are failure to feed and long trigger pull. Mine just doesn't go bang! It requires several pulls of the trigger sometimes to fire some rounds. The occasional failure to feed is not the end of the world if I can get it to go bang.

Are you sure the slide is all the way in battery when you pull the trigger,if the slide is out of battery even a fraction of an inch the firing pin wont make contact but it's possible after several hammer strikes the slide finally goes into battery,something you might want to look into,I found that remington bulk box did not feed well in any of my 22's

my shooting group got so disgusted with the Remington bulk stuff that we all quit buying it. At least 2-3% of the bullets are seated about 10 degrees out of plumb, and few of them are crimped well anyway.

I have almost 250 rds or CCI stingers through it. I asked what they recommended when I bought it new and they said use the CCI stingers, so I bought a few boxes. Then when i got home and opened the box I saw there was a coupon for the CCI stinger ammo. I shot what I had and bought a few more boxes. I would say over 250 rounds and less than 400 rounds down tube and it will fail to fire still about 20% of the time. The slide is all the way forward and you can actually see where the rim of the cartridge has been marked, but I guess it does not have enough power behind the hammer to fire the round. I know rimfire can be a little picky or finicky sometimes, but 20% is not acceptable to me. I am open to almost anything. I have cleaned and lubed and cleaned and lubed till I am blue in the face. I have cleaned it between outing and tried not cleaning also. Same result. I want to throw this stupid thing in the river already! Is there a stronger spring I can install to give the hammer more power behind it? Or something I have not lubed? Many people talk about failure to feed issues or failure eject the spent cartridge, but not too many having the firing problem I am having. I am going to run a few more boxes of ammo through it and if it does not get better I will have to send it back to Sig for warranty. I am reluctant to polish or file or grind on anything until they have looked at it b/c I don't want to void a possible warranty b/c I tried to fix it myself.

I really feel for you there. The Mosquito would be a great "crosstrainer" to work with if you carry a Sig. I thought it would be a nice companion to my P239, and almost had my friend put one back in the safe for me...until I saw all the negativity. I don't normally let those things bother me on "brand specific" discussion forums, but for this much attention to be spent on the Sig forum, I just got a bit reluctant to buy one.

I don't blame you for NOT wanting to shade tree gunsmith the Sig. I agree, after you have attempted to fire the recommended number of rounds for break in (even if it's single shot), box it up and send it in. The Mosquito is the only bad apple in the Sig barrel as far as I know, and rarely do you hear any complaints concerning other models.

I hope you can get it resolved.

Well, I don't know if the Walther P22 is the one you want either. Mine will fire the first bullet of the 10 round magazine, but will absolutely REFUSE to feed the second bullet. This happens with both magazines. You must rack the slide again to feed the second bullet. After racking the slide again, it will fire the remaining 9 bullets. I thought it was dirty so I cleaned and lubed the gun, but it does the same thing with both magazines.

It seems to me that it is a magazine problem. I've checked the web, and sure enough S&W has now issued a redesigned magazine. Hmmmm........they did not inform me about this. I guess I'll be calling S&W to order new mags.

I have heard similar things about the P22. A friend of mine has a new P22 that he TALKS a lot about going to shoot. I have yet to see him break open a box of ammo though. I would try to disassemble the mags make sure there are no burrs on any of the moving parts and clean them real good. It seems there is not nearly as much care taken for the inexpensive line of pistols to ensure good functionality and fit and finish. I have owned two other Sigs and both had impeccable fit and finish and my mosquito feels very cheap compared. But it did cost a third of the others to be fair. I am going to disassemble it past field stripping and look for any burrs or anything funny on some of the internals. If that is only IF I see something that looks funny or just poor workmanship I MIGHT try to polish it if I think it would be relative to my particular problem. I'm not just going to take it apart and polish and sand and grind on stuff cause the other guy said it worked though. It will be at least the weekend before I have a chance to go over to my folks house and try this out. I will let you know soon though. Any other ideas or links to fixes are greatly appreciated.

I too have a sig mosquito, I have had problems with it also, my problem is that the slide lock will not catch after the last round has been fired . Does anybody with an idea as to how to fix the prob? I have put about 250 rounds of Blazer ammo thru it so far, so I am fairly sure that it has been broken in.

Thanks for the help,
