Sig Mosquito auto loading problems

[Steve227]

Hi all,

I've got a Sig Mosquito and for the most part I enjoy it quite a bit. The only problem is that a certain percentage of the time (10-20%) the previous casing won't eject, the slide won't cycle, and obviously the next cartridge won't get loaded.

i've tried 5 or 6 different brands of 22LR. some of them seem to work better for a while but eventually I get a magazine where there will be 3-4 jams.

I've done the basic cleaning of the slide after each range day and lubricated it well.

Any ideas?

Thanks,
Steve

We had the same problem in my wifes...

We solved it by using CCI Stingers.... a bit more recoil to make sure it all works well

Funny you should say that, this one is my wife's as well.

I'll look for those at the local shops. Thanks.

Remember there are 2 springs for different ammo types. My g/f's love CCI stingers as well as the mini mags. Hers cycles Remington thunderbolts amazing as well.

Yeah, you should be using the lighter recoil spring, for sure. CCI Minimags are FLAWLESS in mine (800+ rounds w/o any failure).

The mosquito needs powerful .22 ammo to cycle the action. Mini mags and stingers from cci work the best.

Break it in on mini mags

then afterwords you can should bulk stuff...or at least thats how it worked with mine

Try winchester 333's

Mine is picky with some ammo but it likes cheap winchester 333's from walmart.

The only ammo I had success with running through my Mosquito was CCI Minimags. Hard to find and expensive (for .22's at least) to shoot, so I got rid of it.

I'm really glad to hear that no one has had an easy time with their mosquitos. I felt like such an arse when I was battling with mine. I really wanted to love that gun.

I don't have any difficulty with mine at all. Like I said, it's perfect with Minimags. It also handles Walmart cheap Federal stuff perfectly for about 200 rounds until it start dirtying up the gun (filthy ammo).

If you want accuracy use CCI standard velocity with the light recoil spring . No jams with mine using that combo
