If mini mags don't work, get rid of it.

Try CCI Velocitor and CCI Stinger.

+1 for CCI mini mags - must be the 40 grain version.

If I remember correctly, the word reliability and the Sig Mosquito never went together. Sad really.

Make sure you are holding firmly without limp-wristing.

I generally look for a 40 gr bullet rushing along at 1100 fps or better for a semi auto anything.

If it gags on that recipe I go to work on it. I really hate picky eaters.

I agree with this. Stingers are a nice option, but you shouldn't have to limit yourself to them.

Another vote for CCI stingers. Yes, there expensive relative to other 22 ammo but you do get a nickel coated case for help with corrosion and possibly smoother extraction. They used to be The higher velocity 22 long rifle round and if I remember correctly that was the brand and type that was recommended by a few gun companies who had 22 semi autos that needed that extra recoil from the higher velocity round to help (hopefully) with slide function.

And if I remember they even have a mini hollow point that's designed with a rounded projectile tip so that should help with feeding.
Personally, I also like that it's made in America unlike some of the new Mexican Aguila high velocity stuff.

Lastly, as someone mentioned above it could be some issue/design defect from the factory the gun manufacturers seem to have when designing 22 semi-automatic handguns. I remember when one of walther's full size 22 semi-auto pistols we're having all sorts of problems that people were coming up with homemade fixes on YouTube and Walter might have eventually straightened it out I don't know.

Could be wrong, but I don't believe sig makes the mosquito any longer. There was a big issue with cycling. The stinger looks to be the best bet to see if I can achieve consistency. If not I may just give it away.

And this is why I prefer revolvers for 22 long rifle caliber handguns. Sure you'll still get the occasional dud, that used to happen even more frequently when buying the cheap cheap bulk stuff when I was a kid a million years ago, but you can just pull the trigger again with no need to do a feed malfunction drill.
And if I were you I wouldn't give it away until I tried a few different things like stronger magazine springs, weaker slide springs made by someone reputable like Wolf springs, etc..

Or if you already have a centerfire caliber handgun with roughly the same design you can use this .22 pistol to practice your (guaranteed) failure to feed / eject and clearing the jam drills.

And don't forget to search YouTube for possible easier fixes. It's tougher now because YouTube has put more restrictions on Firearms videos but there still might be something there or one of the gun focused YouTube type video sharing sites like full30.com.
